G.M. Hopkins Company
G. M. Hopkins Company (Griffith M. Hopkins; 1865 - 1940, 1943 - today) was an American civil engineering and surveying firm based in Philadelphia. Founded in Philadelphia in 1865 by brothers Griffith Morgan Hopkins (1834 - 1901) and Henry W. Hopkins (1838 - 1920) as G.M. Hopkins and Company, the firm focused primarily on real estate plat maps of the Eastern seaboard. The firm published 175 plat map atlases depicting cities, counties, and townships in 18 states and the District of Columbia and was among the first to create a cadastral atlas. Henry Hopkins supervised much of the surveying work. G.M. retired in 1900 (and died the following year), which allowed Henry to take control of the business, which he renamed the G.M. Hopkins Company in 1902. Henry retired in 1902 and sold the business to George B. C. Thomas, who had been working for the firm since 1896 as an engraver. The G. M. Hopkins Company was purchased by the Franklin Survey Company of Philadelphia in 1943, which continued publishing atlases under the Hopkins imprint. In 1986, the company was renamed Franklin Maps and is still in operation today.
