Mary Tyler Moore (December 29, 1936 – January 25, 2017) was an American actress, known for her roles in the television sitcoms The Mary Tyler Moore Show (1970–1977), in which she starred as Mary Richards, a single woman working as a local news producer in Minneapolis, and The Dick Van Dyke Show (1961–1966), in which she played Laura Petrie, a former dancer turned Westchester homemaker, wife and mother. Her film work includes 1967's Thoroughly Modern Millie and 1980's Ordinary People, in which she played a role that was very different from the television characters she had portrayed, and for which she was nominated for an Academy Award for Best Actress.
Due to her roles on both The Mary Tyler Moore Show and The Dick Van Dyke Show, in which her characters often broke from stereotypical images of women and pushed gender norms, Moore became a cultural icon and served as an inspiration for many younger actresses, professional women, and feminists. She was later active in charity work and various political causes, particularly the issues of animal rights, vegetarianism and diabetes. She was diagnosed with type 1 diabetes early in the run of The Mary Tyler Moore Show. She also suffered from alcoholism, which she wrote about in her first of two memoirs. She died from cardiopulmonary arrest due to pneumonia at the age of 80 on January 25, 2017.
