Yngve Larsson was born in Sundsvall but moved to Stockholm in the early 1890s with his family.

[1] Originally a Social Democrat, Larsson was expelled from the party in 1915 for proposing Swedish collaboration with Germany in order to guarantee Finland's independence from Russia.

[1][2] During the Second World War Larsson was a leading advocate for pro-Nordic anti-Nazi politics, and a board member of Samfundet Nordens Frihet[1] and chairman of Svensk-Norska föreningen.

Larsson's role in the post-war planning of Stockholm and its new suburbs was internationally recognized.

This has been due I think largely to Yngve Larsson's statesmanship; also to his sympathetic understanding with Markelius and Sidenbladh as architect-planners, and with Holger Blom (an architect, too), who makes the parks throughout Stockholm rich with blooming color.Later judgments, however, have pointed at the sleazy preparatory work; it was for example assumed that the big corporations needed central offices in central Stockholm but when they were offered building lots after the clearances they declined.
