Grandma Moses
Anna Mary Robertson Moses , known by her nickname Grandma Moses, was a renowned American folk artist. Having begun painting in earnest at the age of 78, she is often cited as an example of an individual successfully beginning a career in the arts at an advanced age. Her works have been shown and sold in the United States and abroad and have been marketed on greeting cards and other merchandise. Moses paintings are among the collections of many museums. The Sugaring Off was sold for US1.2 million in 2006.
Five of the ten children born to them survived infancy. Although she loved living in the Shenandoah Valley, in 1905 Anna and Robert moved to a farm in Eagle Bridge, New York at her husbands urging. Thomas Moses died in 1927 of a heart attack, after which her son Forrest helped her operate the farm. She retired and moved to a daughters home in 1936. Anna Mary was known as either Mother Moses or Grandma Moses, and although she first exhibited as Mrs. Moses, the press dubbed her Grandma Moses, and the nickname stuck.
