Andrew Porter (1743–1813) of Pennsylvania was a captain of marines at the beginning of the Revolution, went to the artillery to serve under Henry Knox, and in 1781 was assigned to manufacture gunpowder for use in the Yorktown campaign. After the war Porter farmed for a time, engaged in surveying for the state, and from 1809 until his death served as surveyor general for Pennsylvania. He received no major appointment from GW.
1. No certificate from John Ewing and David Rittenhouse is now among the applications for office in DLC:GW. Porter may have sent a copy of an earlier certificate, 28 Nov. 1784, signed by Ewing, Rittenhouse, and Thomas Hutchins, recommending Porter for his “Qualifications as a Surveyor and Mathematician, and his Character for Integrity, Diligence and Fidelity” (DNA:PCC, item 78). No certificate from Knox has been found.
