Between 1859 and 1862, Coleman studied in
Paris under
Thomas Couture, returning during the
American Civil War to serve with the Union Army during which he was seriously wounded in
South Carolina and recovered in Sharon Springs, New York. He returned to Europe in 1866 with fellow painters
William Morris Hunt and
Elihu Vedder. From 1863 to 1866, Coleman maintained a studio in New York. It was first at 840 and later at 896 Broadway. He regularly showed his work in the exhibitions of the Brooklyn Art Academy and the National Academy of Design in New York. In 1893, Coleman returned to the United States briefly. While there, he was commissioned to paint and decorate the interiors of the New-York State Building at the
Chicago World's Fair, along with fellow artists
Frank D. Millet and Elmer E. Garnsey. In 1899, Avery Galleries at 368
Fifth Avenue in New York held an exhibition with forty of his pictures and drawings. Another was held there in 1902, featuring over fifty paintings and pastels made by Coleman. The place of honor was given to his contribution to the 1901
Pan-American Exposition, held in his hometown of Buffalo, titled
Saintly Dreams by Early Moonlight. It was a saint with a solid golden halo, flowing black hair, a red gown, and a branch of red roses on her lap. The
New York Times stated that she "seems to have felt the languor and bewitchment of a Capri moonlight. She lounges on a white-tiled bench between round stucco columns, flowering shrubs in pots before her, and above her head a lattice running from pillar to pillar. Strong shadows fall about her from the moonlight, leaving her head in the shade." Villa Narcissus was later partly purchased from him by
Rose O'Neill, his friend and also an American artist; he gave her the other half. O'Neill, who is famous for having invented the
Kewpie Doll, permitted Coleman to live out the remainder of his days there, and he remained at the Villa until his death in 1928. ==Personal life==
