Biography
Biography
He was a brother of Arctic explorer Eivind Astrup (1871–1895), merchant Sigurd Astrup (1873–1949) and architect Henning Astrup (1864–1896). His sister Hanna (1869–1933) was married to politician Peter Andreas Morell. He was educated at Kristiania Technical School in 1891-92 and Kristiania Fine Art School the following year. He also attended Technische Hochschule Charlottenburg from 1896 to 1897. In 1899 he started to work as an architect with Henrik Nissen and Henrik Bull. In 1901, he opened architectural practice in Kristiania. From 1934, he worked together with his son, architect Henning Thorvaldsson Astrup (1904–83), under the company name Thorvald and Henning Astrup. Astrup specialized in industrial constructions, particularly related to power production and transmission, factories and dams; many monumental installations were built in neoclassical or functionalistic style. These include Såheim Power Station in Rjukan (1916), Tyssedal Power Station (1906), while the administration building for Norsk Hydro in Rjukan is built in jugendstil style. His neoclassical buildings included the Soria Moria cinema in Oslo (1928). Astrup also designed all of the railway stations on the Tinnoset Line and Rjukan Line. He is buried at a family grave in the Cemetery of Our Saviour.
Astrup-family grave at Vår Frelsers gravlund in Oslo, Norway. Buried here are Harald Astrup (1831–1914) and his wife Emilie Johanne Astrup b. Smith (1836–1915). Their sons Henning Astrup (1864–1896), Eivind Astrup (1871–1895), Sigurd Astrup (1873–1949) and Thorvald Astrup (1876–1940). Thorvald Astrup`s wife Alfhild Astrup b. Ebbesen (1880–1967) is also buried here. Other familymembers: Kaare Astru
