Anna Mary Robertson Moses (September 7, 1860 – December 13, 1961), better known by her nickname of "Grandma Moses," was a renowned American folk artist. She is often cited as an example of an individual successfully beginning a career in the arts at an advanced age. Her family and friends called her either "Mother Moses" or "Grandma Moses," and although she first exhibited as "Mrs. Moses," the press eagerly dubbed her "Grandma Moses," and the nickname stuck.LIFE magazine celebrated her 100th birthday by featuring her on its September 19, 1960 cover.
