August R. Ohman

August R. Ohman, map publisher, draftsman and engraver, operated in New York City from 1898 until circa 1925. In 1898, the G.W. & C.B. Colton firm, which had been one of the major American map publishers of the second half of the 19th century, became Colton, Ohman & Co. and published under that name until about 1901. After 1901, Ohman published maps under the name August R. Ohman, advertising his firm as "successor to the Coltons."
