John M. Olin Foundation was a grant-making foundation established in 1953 by John M. Olin, president of the Olin Industries chemical and munitions manufacturing businesses. Unlike most non-profit foundations, the John M. Olin Foundation was charged to spend all of its assets within a generation of Olin's death, for fear of mission drift over time. It made its last grant in the summer of 2005 and officially disbanded on November 29 of that year after having disbursed over $370 million in funding, primarily to conservative think tanks, media outlets, and law programs at influential universities. The Foundation is most notable for its early support and funding of the law and economics movement.
