Philip Kiliaen van Rensselaer (May 19, 1747 – March 3, 1798) was the second son of Colonel Kiliaen van Rensselaer and Ariaantie (Schuyler). He was a merchant by trade, and his experience in transporting cargo may have helped qualify him as keeper of the Albany arsenal. He was variously referred to as storekeeper, military storekeeper and Commissary for the Northern Department.[1][2]
