"Albert C. Roessler (1883-1952) was a stamp dealer who was best known for his cacheted covers, and examples of his work are sought by collectors.
Roessler was born April 7, 1883, in Newark, N.J., and spent a portion of his early years in Colorado. He was a founding member of the Denver Stamp Club, established December 13, 1905.
Within a few years he was established as a stamp dealer in east Orange, N.J., after a period of Nassau Street (New York) activity.
With the coming of air mail in the US in 1918, Roessler began the creation of cacheted covers. His first cover, according to Barry Newton (A. C. Roessler: Photo Cachet Catalogue, FDC publishing co., 1976), was for the first air mail flight between Washington, New York, and Philadelphia. He published Air Mail Stamp News from 1918 to 1938.
Something of a mystery man, Roessler would never permit his photograph to be published and no confirmed pictures of him are known. Dan Barber in his "Via Air Mail" column in Stamp Collector (September 13, 1980), reproduces two photographs which might be those of Roessler.
Roessler is reported to have gone out of the stamp business in 1940, and he died on January 26, 1952."
Roessler is known for his unique border graphics, original artwork, and rubber stamped cachets used for both FDC and first flight covers.
