Albert Jacques Leon (Albert J. Leon Lithographer; November 17, 1865 - February 5, 1951) was a Lebanese-American lithographer active in New York in the late 19th and early 20th centuries. Leon was born to a French father and Spanish-Palestinian mother in Beirut, Lebanon, then part of the Syrian Arab Republic. He emigrated to the United States in 1885, settling in New York. In 1894, he married Anna Maria Kales (1866 - 1903), a wealthy heiress. In 1894, he was naturalized. The couple moved to Chicago, where they lived for a time, before returning to New York when Kales began suffering from paranoid delusions that she was being targeted for assassination by Irish Nationalists and the Freemasons. For this, she was committed to the Bloomingdale Asylum in 1901, and her death followed shortly after in 1903. Leon continued to work as a lithographer, maintaining offices at 180 Broadway, New York, and lived in the Ansonia building. He joined the National Guard in 1917, when he was 51. He died in Los Angeles in 1951. His corpus of work included both lithography and chromolithographer, mainly in the form of travel posters and other promotional material
