“Today, beloved icon, Mary Tyler Moore, passed away at the age of 80 in the company of friends and her loving husband of over 33 years, Dr. S. Robert Levine,” her rep Mara Buxbaum said in a statement. “A groundbreaking actress, producer, and passionate advocate for the Juvenile Diabetes Research Foundation, Mary will be remembered as a fearless visionary who turned the world on with her smile.”
Mary was best known for her work on The Dick Van Dyke Show and later on The Mary Tyler Moore Show. On the latter series, Mary helped to change the face of TV by playing a career-driven single woman working in TV news. She was nominated for three Emmy awards for her work on the series, and her hat toss in the show's opening credits would go on to become iconic.
Later in her career, she was featured on sitcoms including That ’70s Show and Hot in Cleveland. In 1980 she was nominated for an Academy Award for Best Actress for her role in Ordinary People.
Buzzfeed notes that the actress' health has been declining in the last few years due to her diabetes. In addition to her work as an actress, she was the international chairman for the Juvenile Diabetes Research Foundation.
