Mogens Lassen (20 February 1901 – 14 December 1987) was a Modernist Danish architect and designer. He began his career as a brick layer before attending the Royal Danish Academy of Fine Arts in 1923. He is considered to be one of the fathers of Functionalism within Denmark, the style which brought international fame to Scandinavian design. His early steel furniture show innovations within the International style, while his later wood furniture are iconic within Danish furniture. Lassen received Denmark’s highest honor, the C.F. Hansen Medal in 1971.
