Olav Hammarstrom (1906-2002) was a Finnish-born architect active in Bloomfield Hills, Michigan and Wellfleet, Massachusetts.
Born in Heinola, Finland in 1906, Olav Hammarstrom studied and began his career as an architect in Helsinki. In 1948, Hammarstrom came to the United States to work on a project with Alvar Aalto in Massachusetts. He stayed in the United States after marrying textile artist Marianne Strengell and settled in Bloomfield Hills, Michigan.
Together, Strengell and Hammarstrom served as consultants for the United States government and the United Nations and reported on the cottage industry of weaving in the Philippines and Jamaica. After Strengell retired from the Cranbrook Academy of Art, she and Olav moved to Wellfleet, Massachusetts where Hammarstrom took many commissions.
Olav Hammarstrom died in 2002 in Wellfleet, Massachusetts.
