Edwin Mead Beeler (July 2, 1871 - October 18, 1931) was an American mapmaker, surveyor, businessman, and civil engineer active in Denver, Colorado and New York City, in the early late 19th and 20th centuries. Beeler was born in Cincinnati, Ohio. As a young man he worked as a driver in Cincinnati before taking a clerkship at the Cincinnati offices of the Northern Assurance Company. He remained in this position until about 1895, when he became a 'manufacturing agent.' In search of a better life in the west, he relocated to Denver, Colorado in 1896 or 1897, where he appears in the City Directory as a draughtsman and civil engineer in the employ of the city's Board of Public Works. Given his later career and the content on some of his maps, we suspect Beeler was working on the Denver's tramways. Beeler's earliest maps appear around 1904, all of which focus on Denver. In a rare map, surviving in a single known example, from 1907, he advertises that he makes 'All Kinds of Maps to Order', from his offices at 305 E. Bayaud St. Some are clearly private enterprise, as they contain advertising, others are official-looking maps. He formally established the 'Beeler Map Company' in 1913, when he copyrighted his Official Map of the City and County of Denver, a large format wall map of Denver issued in whiteprint or reverse cyanotype, possibly issued with the support of Denver mapmaker George Clason. Sometime between 1921 and 1930 he relocated to New York City, presumably to retire, but in the 1930s census he is still listed as a 'Street Car Engineer.' Beeler died in 1931 and is buried in Scarsdale, Westchester, New York.
