Carl Oskar Möller, (20 April 1857 - 4 December 1933), was a Swedish architect and public official,[1] since 1896 married to Dagmar Bosse.
Möller was in his time in architectural arrangement terms one of the foremost exponents among Swedish architects.
The years 1879-1881, he made a study trip to Germany, France, England, Italy and Austria and was in the winter of 1879-80 in Paris, as a student at the École des Beaux-Arts (Atelier Guadet).
A bronze copy of the statue of Saint George and the Dragon was built on Möller's initiative and erected in 1912 in a street of Stockholm's Old Town.
Möller's most treasured works are in pure Gothic style with splendid terrace construction like the neo-Gothic St. John's Church, Stockholm (S:t Johannes kyrka), which was inaugurated the 1890.
