Weber was sustained by the respect of some eminent peers, such as photographers Alvin Langdon Coburn and Clarence White, and museum director John Cotton Dana, who saw to it that Weber was the subject of a one-man exhibition at the Newark Museum in 1913, the first modernist exhibition in an American museum. For a few years, Weber enjoyed a productive if rocky relationship with Stieglitz, and he published two essays in Stieglitz's journal "Camera Work". (He also wrote Cubist poems and published a book, "Essays on Art," in 1916.) So poor was Weber in these years that he camped out for some weeks in Stieglitz's gallery. Weber was also closely acquainted with Wilhelmina Weber Furlong and Thomas Furlong, whom he met at the Art Students League, where he taught from 1919 to 1921 and 1926 to 1927. Weber died in Great Neck, New York in 1961. He was the subject of a major retrospective at the Jewish Museum in 1982.
