He studied at the Danish School of Art and Design, and was particularly influenced by Prof. Kaare Klint.
[1] After completing his studies, Wanscher worked with Klint from 1924 to 1927, at which time he set up his own office, specializing in furniture design.
Throughout the 1930s and 1940s, Wanscher, working with master joiner A. J. Iversen, produced dozens of designs that are now seen as modern classics.
In the 1950s, Wanscher left his private firm and began an association with P. Jeppesens Møbelfabrik A/S that would last for the rest of his professional life.
In 2003, Vance Trimble, a furniture dealer and collector, staged a retrospective of Wanscher's work in New York City, which was well received.
