Isak Gustaf Clason

[1] Clason studied engineering and later architecture at the Royal Institute of Technology in Stockholm, where he was a student of Albert Theodor Gellerstedt (1836-1914), and later at the architectural school of the Royal Swedish Academy of Arts, at the time headed by Fredrik Wilhelm Scholander (1816-1881).

It broke new ground in its use of natural material throughout (limestone and bricks) rather than the plaster that had been dominant in Swedish architecture until that point.

During most of the 1880s, Clason ran an architectural firm in Stockholm together with architect Kasper Erik Salin (1856–1919).

[3][4] His largest commission was the Nordic Museum on Djurgården, in North European Renaissance style, which he began in collaboration with architect Magnus Isæus (1841-1890) but continued alone after Isaeus's death in 1890.

The building was partly finished for the Stockholm Exhibition in 1897, and completed a few years later.
