Colonel Beekman was a physician and surgeon and resided in New York and Flatbush, Long Island, and occasionally on his estate on the Millstone River, New Jersey. In 1685 he was Justice of Kings County, New York. He was Captain of militia at Flatbush in 1681, and in 1689, he took the oath of allegiance and was appointed Major of all the horse and foot in Kings County as appears by his military commission published in Historical Documents of New York vol xxxvi., p. 142. In 1690 and 1691 he was a member of Leisler's Council. He did not thoroughly agree with Leisler in politics and when Leisler's conduct caused disturbances, Dr. Beekman prepared and delivered an address in pacification of the people, When Colonel Sloughter came here as Deputy Governor in 1691, to succeed Deputy Governor Nicholson, whose government after the accession of William of Orange had been overthrown by Leisler. Dr. Beekman was arrested with Leisler and others, and was seventeen months in prison, but was afterward pardoned. The unfortunate patriot Leisler was hanged. Governor Benjamin Fletcher who succeeded Colonel Sloughter was in turn succeeded by Governor Bellomont. In 1700 Dr Beekman was appointed Lieutenant-Colonel and then Colonel under Richard Coote, Earl of Bellomont."
