Early life and education
Early life and education
Walter was born on September 4, 1804, in Philadelphia. He was the son of mason and bricklayer Joseph S. Walter and his wife Deborah. His grandfather, Frederick Jacob Walter, emigrated from Germany in 1749 and arrived in Philadelphia as an orphan after both parents died at sea. Walter showed an aptitude for mathematics and drawing at an early age. He worked as a bricklayer for his father during the construction of the Second Bank of the United States and studied architecture in the office of William Strickland. He attended the School of Mechanic Arts at the Franklin Institute in Philadelphia and studied under John Haviland. Later in life, he received an honorary Masters of Arts degree from Madison University in 1849, a Ph.D. from the University of Lewisburg in 1853, and a Doctor of Laws degree from Harvard University in 1857.
Career
Career
Walter established his architectural design practice in 1830. The following year, he was appointed chief architect of the planned Moyamensing Prison. In 1833, the Philadelphia City Council accepted his design for Girard College; he led construction until its completion in 1847. In 1829, Walter was elected to the Franklin Institute; he would serve the museum in several roles, including as professor of architecture in 1841 and as chairman of the Board of Managers in 1846. In 1836, he recommended the creation of the American Institution of Architects and served as secretary. That organization failed, but in 1857, he would help to found the American Institute of Architects, for which he served as vice-president in 1857 and as president from 1876 to 1887. In 1838, the building committee of Girard College funded a European trip for Walter. He visited England, Ireland, France, and Italy to study the architecture and construction of schools and other buildings and gather ideas for his work at the college. In 1839, he was elected to the American Philosophical Society. In 1841, a local economic downturn created financial hardship for Walter. He was forced to sell his house and most of his architectural library. In 1843, he was commissioned to build a breakwater for the port of LaGuaira, Venezuela, and completed the work in 1845.
The U.S. Capitol and its dome
The U.S. Capitol and its dome
• Illustration — Inauguration of Abraham Lincoln, March 4, 1861, beneath the unfinished Capitol dome In 1851, Walter was selected by President Millard Fillmore to lead the expansion of the U.S. Capitol. The office of the Architect of the Capitol, originally part of the Department of the Interior, was from 1853 to 1862 placed under the War Department. Walter's work was supervised by Montgomery C. Meigs and William B. Franklin. Work was discontinued at the outbreak of the American Civil War, and when it started up again in 1862, his department was again supervised by the Department of the Interior. Construction on the wings began in 1851. The House of Representatives met in its new quarters in December 1857 and the Senate occupied its new chamber by January 1859. Walter's fireproof cast-iron dome was authorized by Congress on March 3, 1855, and was nearly completed by December 2, 1863, when the Statue of Freedom was placed on top. The dome's cast-iron frame was made by the iron foundry Janes, Fowler, Kirtland & Co. The 36 Corinthian columns designed by Walter, as well as 144 cast-iron structural pillars for the dome, were supplied by the Baltimore ironworks of Poole & Hunt. Walter also rebuilt the interior of the Library of Congress' west center building after the fire of 1851. Walter continued as Capitol architect until 1865, when he resigned his position over a minor contract dispute. After 14 years in Washington, he retired to Philadelphia. In the 1870s, financial setbacks forced Walter from retirement. He worked for a year as a draftsman for the Pennsylvania Railroad. He worked as Chief Assistant to his friend and younger colleague John McArthur Jr., when he won the design competition for Philadelphia City Hall. He continued on that vast project until his death in 1887. He was interred at Laurel Hill Cemetery in Philadelphia.
