Helen Frankenthaler passed away at her home in Darien, Connecticut, yesterday. She was one of the most influential artists of her time, a second-generation Abstract Expressionist who developed a method of painting best known as Color Field. She lived a glamorous life, from her marriage to Robert Motherwell through her later years, including a dance at the White House with a man who turned out to be John Travolta. Art historian Phyllis Tuchman has written for many publications including Art Forum, Art in America and Obit magazine. She knew Frankenthaler as a friend for 43 years.
