Dinsmore, Andrew F. (1843 - 1925)

Andrew F. Dinsmore (1843 - 1925) was a draughtsman and cartographer who worked for the U.S. Government's General Land Office, working his way up to Principal Draughtsman by the early 20th century. As a result, he was involved in the production of many of the G.L.O.'s hallmark maps of the late 19th and early 20th century. Dinsmore was born in Michigan and served in the U.S. Civil War, achieving the rank of Corporal (he is buried in Arlington National Cemetery). He looks to have resided in Detroit for a period after the war, but by 1868, he had relocated to Washington, D.C. In city directories, his occupation is listed variously as printer, draughtsman, or government clerk, but at any rate began producing maps for the G.L.O. by 1876 and continued to do so until soon before his death.
