Isabel Branson Cartwright

Isabel Parke Branson Cartwright (September 4, 1885 – June 7, 1966) was an American artist born in Coatesville, Pennsylvania.

Cartwright attended the Philadelphia School of Design for Women. In 1906, she won the 'Alumnae Award', a European fellowship allowing her to go abroad for a year.

In November 1910, she married John Reagan Cartwright in El Paso, Texas. They moved to Terrell, Texas until her husband's death in 1917. She went on to have one-woman art shows in San Antonio and Fort Worth, Texas. Considered one of the mainstays of the group, she exhibited in all sixty-five shows that it held, over a twenty-eight year span from 1917 to 1945.

Cartwright had a house in the 1940s on Monhegan Island, off the coast of Maine, where she liked to paint.
