When it comes to the most famous 20th century painters of the United States , Grandma Moses should be mentioned，although she did not start painting until she was in her late seventies．As she once said to herself：" I would never sit back in a rocking chair，waiting for someone to help me．" No one could have had a more active old age．

She was born on a farm in New York State，one of five boys and five girls．At 12 she left home and was in domestic service until at 27 she married Thomas Moses，the hired hand of one of her employers. They farmed most of their lives, first in Virginia and then in New York State, at Eagle Bridge. She had ten children, of whom five survived；her husband died in 1927．

Grandma Moses painted a little as a child and made embroidery(刺绣) pictures as a hobby，but only changed to oils in old age because her hands became too stiff(僵硬的) to sew and she still wanted to keep busy and pass the time．Her pictures were first sold at the local drugstore and at a market and were soon noticed by a businessman who bought all that she painted．Three of the pictures were exhibited(展览) in the Museum of Modern Art，and in 1940 she had her first exhibition in New York．Between the 1930's and her death，she produced some 2,000 pictures：careful and lively portrayals of the country life she had known for so long，with a wonderful sense of color and form．"I think really hard till I think of something really pretty，and then I paint it" she said．
