Simon Bradstreet, English colonial magistrate (d. 1697)
Simon Bradstreet (baptized March 18, 1603/4 – March 27, 1697) was a colonial magistrate, businessman, diplomat, and the last governor of the Massachusetts Bay Colony. Arriving in Massachusetts on the Winthrop Fleet in 1630, Bradstreet was almost constantly involved in the politics of the colony but became its governor only in 1679. He served on diplomatic missions and as agent to the crown in London, and also served as a commissioner to the New England Confederation. He was politically comparatively moderate, arguing minority positions in favor of freedom of speech and for accommodation of the demands of King Charles II following his restoration to the throne.

Bradstreet was married to Anne, the daughter of Massachusetts co-founder Thomas Dudley and New England's first published poet. He was a businessman, investing in land and shipping interests. Due to his advanced age (he died at 93) Cotton Mather referred to him as the "Nestor of New England". His descendants include U.S. President Herbert Hoover and Supreme Court justices Oliver Wendell Holmes Jr. and David Souter.
