Johannes "John" Jacobse Beekman (August 8, 1733 - December 17, 1802) was a New York politician and businessman of Dutch descent. He served as Mayor of Albany, New York and a member of the New York State Assembly.
Beekman was born on August 8, 1733.[1] He was the youngest of six children born to Debora (Hansen) Beekman and Jacob Beekman (1685–1739), an Albany businessman and blacksmith.[2] His sister, Debora Beekman, married Gerrit Staats.[3]
His paternal grandparents were Johannes Beekman, who was married to Machtel (Schermerhorn) Beekman. His aunt, Maritje "Mary" Beekman, was the wife of Arnout Schermerhorn (grandparents of merchant Peter Schermerhorn and great-grandparents of Abraham Schermerhorn).[4]
Beekman was a successful merchant who was one of the wealthiest Albany landowners. In 1756, he was appointed firemaster. In 1763, he was elected Assistant Alderman in the second ward. After several years as assistant Alderman, he was elected Alderman in September 1775. Beekman also served in the Albany County militia becoming a lieutenant by 1768.[2]
Early in Revolutionary War, Beekman supported the Continental Army and signed the "General Association" in 1776.
