Sigurd Frosterus

Frosterus had an architectural office from 1902–1904 with Gustaf Strengell and from 1918–1935 with Ole Gripenberg. Frosterus and Strengell designed villas and manor houses, including Tamminiemi, which was an official residence of the President of Finland from 1940 until 1981. Frosterus's best-known work is the Stockmann department store in Helsinki. The architecture competition was held in 1916, but the building was not finished until 1930. Frosterus inspired numerous Finnish artists with his art theories and criticism. He collected post-impressionist art. Frosterus was the editor of Arkkitehti magazine from 1908–1911, and published books on art theory. He was also a talented watercolour painter.
