Field Museum of Natural History

The museum is run by a private Board of Trustees and funded through a combination of ticket sales, memberships, donations, endowments, and grants, along with some public funding for specific programs or maintenance. The permanent exhibitions, which attract up to 2 million visitors annually, include fossils, current cultures from around the world, and interactive programming demonstrating today's urgent conservation needs. The museum is named in honor of its first major benefactor, Marshall Field, the department-store magnate. The museum and its collections originated from the 1893 World's Columbian Exposition and the artifacts displayed at the fair. The museum maintains a temporary exhibition program of traveling shows, as well as in-house produced topical exhibitions. The professional staff maintains collections of over 24 million specimens and objects that provide the basis for the museum's scientific-research programs. These collections include the full range of existing biodiversity, gemstones, meteorites, fossils, and extensive anthropological collections and cultural artifacts from around the globe. The museum's library, which contains over 275,000 books, journals, and photo archives focused on biological systematics, evolutionary biology, geology, archaeology, ethnology and material culture, supports the museum's academic-research faculty and exhibit development. The academic faculty and scientific staff engage in field expeditions, in biodiversity and cultural research on every continent, in local and foreign student training, and in stewardship of the rich specimen and artifact collections. They work in close collaboration with public programming exhibitions and education initiatives.

• Illustration — Daniel Giraud Elliot in 1897 In 1869, and before its formal establishment, the museum acquired the largest collection of birds and bird descriptions, from artist and ornithologist Daniel Giraud Elliot. In 1894, Elliot would become the curator of the Department of Zoology at the museum, where he worked until 1906. To house the exhibits and collections assembled for the World's Columbian Exposition for future generations, Edward Ayer convinced the merchant Marshall Field to fund the establishment of a museum. Originally titled the Columbian Museum of Chicago in honor of its origins, the Field Museum was incorporated by the State of Illinois on September 16, 1893, for the purpose of the "accumulation and dissemination of knowledge, and the preservation and exhibition of artifacts illustrating art, archaeology, science and history". The Columbian Museum of Chicago occupied the only building remaining from the World's Columbian Exposition in Jackson Park, the Palace of Fine Arts. It is now home to the Chicago Museum of Science and Industry. In 1905, the museum's name was changed to Field Museum of Natural History to honor its first major benefactor and to reflect its focus on the natural sciences. • Illustration — Stanley Field, Field Museum President, 1906 Stanley Field was the president in 1906. During the period from 1943 to 1966, the museum was known as the Chicago Natural History Museum. In 1921, the Museum moved from its original location in Jackson Park to its present site on Chicago Park District property near downtown Chicago. By the late 1930s the Field Museum had emerged as one of the three premier museums in the United States, the other two being the American Museum of Natural History in New York City and the National Museum of Natural History at the Smithsonian Institution in Washington, DC. The museum has maintained its reputation through continuous growth, expanding the scope of collections and its scientific research output, in addition to its award-winning exhibitions, outreach publications, and programs. The Field Museum is part of Chicago's lakefront Museum Campus that includes the John G. Shedd Aquarium and the Adler Planetarium. In 2015, it was reported that an employee had defrauded the museum of $900,000 over a seven-year period to 2014. • Illustration — North Hall, circa 1895 • Illustration — Stanley Field Hall in 2020 • Illustration — The Tsavo Maneaters on display in Mammals of Africa exhibit hall

The Museum received 1,018,002 visitors in 2022, ranking the 21st most-visited museum in the United States.

Animal exhibitions and dioramas such as Nature Walk, Mammals of Asia, and Mammals of Africa allow visitors an up-close look at the diverse habitats that animals inhabit. Most notably featured are the man-eating lions of Tsavo. The Mfuwe man eating lion is also on display. • Species represented in the Animal Halls — Gallery • Aardvark — Mammals of Africa • African Buffalo — Mammals of Africa • African Elephant — Stanley Field Hall • Alaskan Brown Bear — Messages from the Wilderness • Argali — Mammals of Asia • Barasingha — Mammals of Asia • Beaver — Messages from the Wilderness • Beisa Oryx — Mammals of Africa • Bengal Tiger — Mammals of Asia • Blackbuck Antelope — Mammals of Asia • Black Rhinoceros — Mammals of Africa • Black Wildebeest — Mammals of Africa • Bongo — Mammals of Africa • Burchell's Zebra — Mammals of Africa • Capybara — Messages from the Wilderness • Caribou — Messages from the Wilderness • Caribbean Manatee — Sea Mammals • Cattle Egret — Mammals of Asia • Cheetah — Mammals of Africa • Chital — Mammals of Asia • Common Eland — Mammals of Africa • Cougar — Messages from the Wilderness • Dibatag — Mammals of Africa • Lion — Mammals of Africa • Elephant Seal — Sea Mammals • Gaur — Mammals of Asia • Gelada Baboon — Mammals of Africa • Gerenuk — Mammals of Africa • Giant Anteater — Messages from the Wilderness • Giant Forest Hog — Mammals of Africa • Giant Panda — Mammals of Asia • Giant Sable Antelope — Mammals of Africa • Glacier Bear — Messages from the Wilderness • Grant's Gazelle — Mammals of Africa • Greater Kudu — Mammals of Africa • Guanocos — Messages from the Wilderness • Hog Deer — Mammals of Asia • Hyacinth Macaws — Messages from the Wilderness • Ibex — Mammals of Asia • Imperial Woodpecker — Messages from the Wilderness • Indian Gazelle — Mammals of Asia • Indian Rhinoceros — Mammals of Asia • Indian Sambar — Mammals of Asia • Jaguar — Messages from the Wilderness • Leopard — Mammals of Asia • Lesser Kudu — Mammals of Africa • Mantled Guereza — Mammals of Africa • Malay Tapir — Mammals of Asia • Marsh Deer — Messages from the Wilderness • Mexican Grizzly Bear — Messages from the Wilderness • Mountain Nyala — Mammals of Africa • Mule Deer — Messages from the Wilderness • Muskoxen — Messages from the Wilderness • Narwhal — Sea Mammals • Nilgai — Mammals of Asia • Northern Fur Seal — Sea Mammals • Orangutan — Mammals of Asia • Plains Zebra — Mammals of Africa • Polar Bear — Messages from the Wilderness • Proboscis Monkey — Mammals of Asia • Pronghorn — Messages from the Wilderness • Reticulated Giraffe — Mammals of Africa • Roosevelt Elk — Messages from the Wilderness • Sea Otter — Sea Mammals • Sloth Bear — Mammals of Asia • Snow Leopard — Mammals of Asia • Somali Wildass — Mammals of Africa • Spotted Hyena — Mammals of Africa • Striped Hyena — Mammals of Asia • Swayne's Hartebeest — Mammals of Africa • Takin — Mammals of Asia • Tapir — Messages from the Wilderness • Thomas' Uganda Kob — Mammals of Africa • Walrus — Sea Mammals • Wart Hog — Mammals of Africa • Water Buffalo — Mammals of Asia • Weddell Seal — Sea Mammals • White Rhinoceros — Mammals of Africa • Yellow-checked Gibbon — Mammals of Asia

Evolving Planet follows the evolution of life on Earth over 4 billion years. The exhibit showcases fossils of single-celled organisms, ancient Invertebrates, early fish, Permian synapsids, dinosaurs, extinct mammals, and early hominids. The Field Museum's non-mammalian synapsid collection consists of over 1100 catalogued specimens, including 46 holotypes. The collection of basal synapsids includes 29 holotypes of caseid, ophiacodontid, edaphosaurid, varanopid, and sphenacodontid species – approximately 88% of catalogued specimens. • Species represented in Evolving Planet — Type — Specimen Notes • Cardipeltis — agnathan — fossil skeleton — • Drepanaspis — agnathan — fossil skeleton — • Tiktaalik — sarcopterygian — fossil skeleton — • Acheloma — temnospondyl — fossil skeleton — • Bradysaurus — pareiasaur — fossil skeleton — • Cacops — dissorophid temnospondyls — fossil skeleton — • Captorhinus — captorhinid — fossil skeleton — • Casea — pelycosaur synapsids — fossil skeleton — • Dicynodont — anomodont therapsids — fossil skeleton — • Edaphosaurus — edaphosaurid synapsid — fossil skeleton — • Eryops — temnospondyl — fossil skeleton — • Jonkeria — dinocephalians — fossil skull — • Labidosaurus — anapsid reptile — fossil skeleton — • Lycaenops — carnivorous therapsids — fossil skull — • Ophiacodon — ophiacodontidae synapsid — fossil skeleton — • Seymouria — primitive tetrapod — fossil skeleton — • Diasparactus — diadectid reptiliomorph — fossil skeleton — • Sphenacodon — synapsid — fossil skeleton — • Varanops — varanopid synapsid — fossil skeleton — • Anchiceratops — ceratopsid dinosaur — fossil skull — • Apatosaurus — sauropod dinosaur — fossil skeleton — • Allosaurus — theropod dinosaur — fossil skull — • Archaeopteryx — theropod dinosaur — fossil skeleton — • Brachiosaurus — sauropod dinosaur — Holotype in permanent collections, mounted cast/model outside 2000 - 2023 — • Buitreraptor — dromaeosaurid theropod dinosaur — fossil skeleton — • Cryolophosaurus — theropod dinosaur — fossil skull — • Daspletosaurus — theropod dinosaur — fossil skeleton — • Deinonychus — dromaeosaurid theropod dinosaur — fossil skeleton — • Herrerasaurus — herrerasauridae dinosaur — fossil skeleton — • Lambeosaurus — hadrosaurid dinosaur — fossil skeleton — • Maiasaura — hadrosaurid dinosaur — fossil skeleton — • Majungasaurus — abelisaurid theropod dinosaur — fossil skull — • Masiakasaurus — theropod dinosaurs — fossil skull — • Parasaurolophus — saurolophine hadrosaurid dinosaurs — fossil skeleton — • Protoceratops — ceratopsian dinosaur — fossil skeleton — • Rapetosaurus — sauropod dinosaur — fossil skeleton — • Stegosaurus — thyreophoran dinosaur — fossil skeleton — • Triceratops — ceratopsid dinosaur — fossil skeleton — • Tyrannosaurus rex — coelurosaurian theropod dinosaur — fossil skeleton — • Arctodus — short-faced bear — fossil skeleton — • Barylambda — pantodont — fossil skeleton — • Basilosaurus — prehistoric cetacean — fossil skeleton, pelvis with hind limbs — • Coryphodon — pantodont — fossil skeleton — • Eobasileus — uintathere — fossil skull — • Glyptodon — glyptodont — fossil skeleton — • Mastodon — proboscidean — fossil skeleton — • Megatherium — giant ground sloth — fossil skeleton — • Paramylodon — giant ground sloth — fossil skeleton — • Pronothrotherium — ground sloth — fossil skeleton — • Rodhocetus — prehistoric cetacean — fossil skeleton, pelvis with hind limb — • Smilodon — saber-toothed cat — fossil skeleton — • Thylacosmilus — saber-toothed metatherian — fossil skull — • Ursus spelaeus — cave bear — fossil skeleton — • Woolly Mammoth — proboscidean — fossil skeleton —

Inside Ancient Egypt offers a glimpse into what life was like for ancient Egyptians. Twenty-three human mummies are on display as well as many mummified animals. The exhibit features a three-story replica (featuring two authentic rooms with 5,000-year-old hieroglyphs) of the mastaba tomb of Unas-Ankh, the son of Unas (the last pharaoh of the Fifth Dynasty). Also displayed are an ancient marketplace showing artifacts of everyday life, a shrine to the cat goddess Bastet, and dioramas showing the afterlife preparation process for the dead. In 2024 the museum performed CT scans on 26 of their mummies.

• Illustration — This replica of an Aztec sun stone is displayed in the Ancient Americas exhibit. It depicts the Aztec creation myth. The Ancient Americas displays 13,000 years of human ingenuity and achievement in the Western Hemisphere, where hundreds of diverse societies thrived long before the arrival of Europeans. In this large permanent exhibition visitors can learn the epic story of the peopling of these continents, from the Arctic to the tip of South America. The exhibit consists of six displays: Ice Age Hunters, Innovative Hunters and Gatherers, Farming Villagers, Powerful Leaders, Rulers and Citizens, and Empire Builders. Visitors are encouraged to begin with Ice Age Hunters and conclude with Empire Builders. In this way, visitors can understand the cultural and economic progression of the Ancient Americas. Throughout the exhibit, collections are displayed in a way that emphasizes the cultural context of the artifacts. The six displays draw from the Field Museum's massive North America collection. Significant collections utilized by the exhibit include pre-Columbian artifacts gathered by Mayanists Edward H. Thompson and John E. S. Thompson. Additionally, former curator Paul Sidney Martin's American Southwest collection makes up a significant portion of the "Farming Villagers" display. The Empire Builders display includes Aztec and Incan artifacts gathered in the 19th century. The Ancient Americas exhibit transitions to the Alsdorf Hall of Northwest Coast and Arctic Peoples and eventually the Native Truths: Our Voices, Our Stories exhibit. This emphasizes the thematic unity of the Field Museum's American collections.

Cultural exhibitions include sections on Tibet and China, where visitors can view traditional clothing. There is also an exhibit on life in Africa, where visitors can learn about the many different cultures on the continent, and an exhibit where visitors may "visit" several Pacific Islands. The museum houses an authentic 19th-century Māori Meeting House, Ruatepupuke II, from Tokomaru Bay, New Zealand. Additionally, the Field Museum's Northwest Coast Collections showcase the early work of Franz Boas and Frederic Ward Putnam's work with the Kwakwakaʼwakw (Kwakiutl) people in the Alsdorf Hall of Northwest Coast and Arctic Peoples. Finally, the Native Truths: Our Voices, Our Stories permanent exhibition displays the Field Museum's current collaborative efforts with the indigenous people of North America.

The Africa cultural hall opened at the Field Museum in November 1993. It offers 14 different displays that are primarily ethnographic in nature. Several African countries are exhibited as well as a variety of geographical areas including the Sahara and East African rift valley. The final section is dedicated to the African diaspora with a particular focus on the impact of the slave trade on the continent. The Africa permanent exhibit owes most of its collection to the efforts of Wilfred D. Hambly.

• Illustration — Pacific Northwest totem poles This extensive permanent exhibition covers two culture areas that were vitally important to the early work of the Field Museum—the Arctic and Pacific Northwest. The Pacific Northwest collection is more extensive, but both collections are organized into four categories: subsistence, village and society, the spiritual world, and art. Major displays include a variety of dioramas and a large collection of totem poles. The current permanent exhibition has its origins in the Maritime Peoples hall created by the Field Museum's curator of North American archaeology and ethnology James VanStone.

• Illustration — This statue of the divine protector Wei Tuo is one of many artifacts on display at the Cyrus Tang Hall of China at the Field Museum of Natural History. The Cyrus Tang Hall of China opened as a permanent exhibition in 2015. The hall consists of five sections: Diverse Landscapes, Ritual and Power, Shifting Power, Beliefs and Practices, and Crossing Boundaries. The first three sections are organized chronologically while the final two sections are organized by theme. Three hundred and fifty objects are displayed throughout the five galleries. These artifacts are a sample chosen from the Field Museum's significant China collection. This collection was gathered by the sinologist Berthold Laufer.

Native Truths: Our Voices, Our Stories opened as a permanent exhibition in 2021. This exhibit is an extensive renovation of the former Native American Hall at the Field Museum. Native Truths utilizes about 400 artifacts to interpret Native American culture and history while also addressing modern-day challenges. The exhibition is a result of a changing attitude towards Native Americans that emphasized Native peoples instead of Native artifacts.

• Illustration — This authentic Maori Meeting House is displayed in the Field Museum's Regenstein Halls of the Pacific. This exhibit is dedicated to the natural and cultural history of the Pacific Islands and is organized into five different sections: the natural history of the islands, the cultural origins of Pacific Islanders, a canoe display, an ethnographic collection showcasing New Guinea's Huon Gulf, and a modern Tahitian market. The final portion of the exhibit is dedicated to the ceremonial arts of the Pacific peoples. The majority of the collection was gathered by curator Albert Buell Lewis. Building upon Lewis' desire to portray cultures as living and participative, the exhibit was intentionally designed to demonstrate how the Pacific Islands interact with the contemporary world.

The Grainger Hall of Gems consists of a large collection of diamonds and gems from around the world, and also includes a Louis Comfort Tiffany stained glass window. The Hall of Jades focuses on Chinese jade artifacts spanning 8,000 years. The Robert A. Pritzker Center for Meteoritics and Polar Studies contains a large collection of fossil meteorites.

The Underground Adventure gives visitors a bug's-eye look at the world beneath their feet. Visitors can see what insects and soil look like from that size, while learning about the biodiversity of soil and the importance of healthy soil.

• DNA Discovery Center – Visitors can watch real scientists extract DNA from a variety of organisms. Museum goers can also speak to a live scientist through the glass every day and ask them any questions about DNA. • McDonald's Fossil Prep Lab – The public can watch as paleontologists prepare real fossils for study. • The Regenstein Pacific Conservation Laboratory – 1600 sqft conservation and collections facility. Visitors can watch as conservators work to preserve and study anthropological specimens from all over the world.

• Illustration — Sue, the largest and most complete (90%) Tyrannosaurus rex skeleton yet discovered On May 17, 2000, the Field Museum unveiled Sue, the largest T. rex specimen discovered at the time. Sue has a length of 40.5 ft, stands 13 ft tall at the hips, and has been estimated at 8.4 - as of 2018. The specimen is estimated to be 67 million years old. The fossil was named after the person who discovered it, Sue Hendrickson, and is commonly referred to as female, although the dinosaur's actual sex is unknown. The original skull is not mounted to the body due to the difficulties in examining the specimen 13 feet off the ground, and for nominal aesthetic reasons (the replica does not require a steel support under the mandible). An examination of the bones revealed that Sue died at age 28, a record for the fossilized remains of a T. rex until Trix was found in 2013. In December 2018 after revisions of the skeletal assembly were made to reflect new concepts of Sue's structure, display of the skeleton was moved into a new suite in The Griffin Halls of Evolving Planet.

The library at the Field Museum was organized in 1893 for the museum's scientific staff, visiting researchers, students, and members of the general public as a resource for research, exhibition development and educational programs. The 275,000 volumes of the Main Research Collections concentrate on biological systematics, environmental and evolutionary biology, anthropology, botany, geology, archaeology, museology and related subjects. The Field Museum Library includes the following collections:

The Field Museum's Double Elephant folio of Audubon's The Birds of America is one of only two known copies that were arranged in taxonomic order. Additionally, it contains all 13 composite plates. The Field's copy belonged to Audubon's family physician Dr. Benjamin Phillips.

The Field Museum offers opportunities for informal and more structured public learning. Exhibitions remain the primary means of informal education, but throughout its history the Museum has supplemented this approach with innovative educational programs. The Harris Loan Program, for example, begun in 1912, reaches out to children in Chicago area schools, offering artifacts, specimens, audiovisual materials, and activity kits. The Department of Education, begun in 1922, offers classes, lectures, field trips, museum overnights and special events for families, adults and children. The Field has adopted production of the YouTube channel The Brain Scoop, hiring its host Emily Graslie full-time as 'Chief Curiosity Correspondent'. The Museum's curatorial and scientific staff in the departments of Anthropology, Botany, Geology, and Zoology conducts basic research in systematic biology and anthropology, besides its responsibility for collections management, and educational programs. It has long maintained close links, including joint teaching, students, seminars, with the University of Chicago and the University of Illinois at Chicago. Professional symposia and lectures, like the annual A. Watson Armour III Spring Symposium, present scientific results to the international scientific community and the public at large.

The museum used to publish four peer-reviewed monograph series issued under the collective title Fieldiana, devoted to anthropology, botany, geology and zoology.

Professionally managed and maintained specimen and artifact collections, such as those at the Field Museum of Natural History, are a major research resource for the national and international scientific community, supporting extensive research that tracks environmental changes, benefits homeland security, public health and safety, and serves taxonomy and systematics research. Many of Field Museum's collections rank among the top ten collections in the world, e.g., the bird skin collection ranks fourth worldwide; the mollusk collection is among the five largest in North America; the fish collection is ranked among the largest in the world. The scientific collections of the Field Museum originate from the specimens and artifacts assembled between 1891 and 1893 for the World Columbian Exposition. Already at its founding, the Field Museum had a large anthropological collection. A large number of the early natural history specimens were purchased from Ward's Natural History Establishment in Rochester, New York. An extensive acquisition program, including large expeditions conducted by the museum's curatorial staff resulted in substantial collection growth. During the first 50 years of the museum's existence, over 440 Field Museum expeditions acquired specimens from all parts of the world. In addition, material was added through purchase, such as H. N. Patterson's herbarium in 1900, and the Strecker butterfly collection in 1908. Extensive specimen material and artifacts were given to the museum by collectors and donors, such as the Boone collection of over 3,500 East Asian artifacts, consisting of books, prints and various objects. In addition, "orphaned collections" were and are taken in from other institutions such as universities that change their academic programs away from collections-based research. For example, already beginning in 1907, Field Museum accepted substantial botanical specimen collections from universities such as University of Chicago, Northwestern University and University of Illinois at Chicago, into its herbarium. These specimens are maintained and continuously available for researchers worldwide. The Index Herbariorum code assigned to this botanic garden is F and it is used when citing housed specimens. Targeted collecting in the US and abroad for research programs of the curatorial and collection staff continuously add high quality specimen material and artifacts; e.g., Dr. Robert Inger's collection of frogs from Borneo as part of his research into the ecology and biodiversity of the Indonesian fauna. Collecting of specimens and acquisition of artifacts is nowadays subject to clearly spelled-out policies and standards, with the goal to acquire only materials and specimens for which the provenance can be established unambiguously. All collecting of biological specimens is subject to proper collecting and export permits; frequently, specimens are returned to their country of origin after study. Field Museum stands among the leading institutions developing such ethics standards and policies; Field Museum was an early adopter of voluntary repatriation practices of ethnological and archaeological artifacts.

Field Museum collections are professionally managed by collection managers and conservators, who are skilled in preparation and preservation techniques. Numerous maintenance and collection management tools were and are being advanced at Field Museum. For example, Carl Akeley's development of taxidermy excellence produced the first natural-looking mammal and bird specimens for exhibition as well as for study. Field Museum curators developed standards and best practices for the care of collections. Conservators at the Field Museum have made notable contributions to conservation science with methods of preservation of artifacts including the use of pheromone trapping for control of webbing clothes moths. The Field Museum was an early adopter of positive-pressure based approaches to control of environment in display cases, using control modules for humidity control in several galleries where room-level humidification was not practical. The museum has also adopted a low-energy approach to maintain low humidity to prevent corrosion in archaeological metals using ultra-well-sealed barrier film micro-environments. Other notable contributions include methods for dyeing Japanese papers to color match restorations in organic substrates, the removal of display mounts from historic objects, testing of collections for residual heavy metal pesticides, presence of early plastics in collections, the effect of sulfurous products in display cases, and the use of light tubes in display cases. Concordant with research developments, new collection types, such as frozen tissue collections, requiring new collecting and preservation techniques are added to the existing holdings. Despite the passage of the Native American Graves Protection and Repatriation Act in 1990, the Field Museum is estimated to hold more than 1000 Native American remains that have not been repatriated.

• Illustration — Night view of the north front exterior of the museum Collection management requires meticulous record keeping. Handwritten ledgers captured specimen and artifact data in the past. Field Museum was an early adopter of computerization of collection data beginning in the late 1970s. Field Museum contributes its digitized collection data to a variety of online groups and platforms, such as: HerpNet, VertNet and Antweb, Global Biodiversity Information Facility (also known as GBif), and others. All Field Museum collection databases are unified and currently maintained in KE EMu software system. The research value of digitized specimen data and georeferenced locality data is widely acknowledged, enabling analyses of distribution shifts due to climate changes, land use changes and others.

During the World's Columbian Exposition, all acquired specimens and objects were on display; the purpose of the World's Fair was exhibition of these materials. For example, just after opening of the Columbian Museum of Chicago, the mollusk collection occupied one entire exhibit hall, displaying 3,000 species of mollusks on about 1260 sqft. By 1910, 20,000 shell specimens were on display, with an additional 15,000 "in storage". Only a small fraction of the specimens and artifacts are publicly displayed. The vast majority of specimens and artifacts are used by a wide range of people in the museum and around the world. Field Museum curatorial faculty and their graduate students and postdoctoral trainees use the collections in their research and in training e.g., in formal high school and undergraduate training programs. Researchers from all over the world can search online for particular specimens and request to borrow them, which are shipped routinely under defined and published loan policies, to ensure that the specimens remain in good condition. For example, in 2012, Field Museum's Zoology collection processed 419 specimen loans, shipping over 42,000 specimens to researchers, per its Annual Report. The collection specimens are an important cornerstone of research infrastructure in that each specimen can be re-examined and with the advancement of analytic techniques, new data can be gleaned from specimens that may have been collected more than 150 years ago.

This private collection of Edward E. Ayer, the first president of the museum, contains virtually all the important works in the history of ornithology and is especially rich in color-illustrated works.

The working collection of Dr. Berthold Laufer, America's first sinologist and Curator of Anthropology until his death in 1934, consists of about 7,000 volumes in Chinese, Japanese, Tibetan, and numerous Western languages on anthropology, archaeology, religion, science, and travel.

The photo archives contain over 250,000 images in the areas of anthropology, botany, geology and zoology and documents the history and architecture of the museum, its exhibitions, staff and scientific expeditions. In 2008 two collections from the Photo Archives became available via the Illinois Digital Archives (IDA): The World's Columbian Exposition of 1893 and Urban Landscapes of Illinois. In April 2009, the Photo Archives became part of Flickr Commons.
