Hollywood's Notable Deaths of 2012

She was the wife of the late Hollywood producer David Brown, whose films included Jaws, The Sting, Cocoon, Driving Miss Daisy and The Verdict. They married in 1959 and were together for more than 50 years until Brown's death at age 93 on Feb. 1, 2010. The powerful pair were often the toast of the New York social scene, always impeccably dressed.

Brown's 1962 best-selling book, Sex and the Single Girl, was an opening act for her 30-plus-year leadership of Cosmopolitan. It was made into a hit movie starring Natalie Wood and Tony Curtis and is considered to be a major impetus of the sexual revolution of the 1960s.

The tiny Arkansas native started her career at the William Morris Agency in New York and worked her way up to being considered the savior of Cosmopolitan magazine, which she joined in 1965. She was editor in chief of Hearst's famed title -- one of its most successful magazines -- for a full 32 years.

She left Cosmo in 1997 but stayed on at Hearst to oversee the now-64 international editions of the magazine. It remains one of Hearst's top-grossing magazines and one of the best-performing magazines of all time.

In January, Brown gave $30 million to Columbia and Stanford universities, creating the David and Helen Gurley Brown Institute for Media Innovation.
