Gail Zappa, who was the keeper of her husband's legacy, lost her battle with cancer on Wednesday (07Oct15). Cancer also claimed the life of her husband in 1993.

The couple wed in 1967 and had four children - Diva, Dweezil, Ahmet and Moon.

Just three months ago, Gail officially gave actor-turned-director Alex Winter the OK to make a documentary about Frank. The Bill & Ted's Excellent Adventure star will also write and produce the project in co-operation with the Zappa Family Trust, a collaboration which allows Winter exclusive access to the Zappa Vault.

Announcing the news to fans in July (15), Gail Zappa said, "We couldn't be happier to be working with Alex, an extraordinary filmmaker in his own right... We also like his attitudinal position."

A spokesman for the Zappa Family Trust tells WENN, "Gail Zappa, nee Adelaide Gail Sloatman, age 70, departed this earth peacefully at her home on Wednesday, October 7, 2015, surrounded by her children.

"Married to Frank Zappa at age 22, Gail was a doe-eyed, barefooted trailblazer, giving equal value to her domestic and professional responsibilities as matriarch of the family and overseer of all Zappa enterprises. She devoted herself to partnering with her husband in the music business and raising their children, Moon Unit, Dweezil, Ahmet and Diva.

"Gail enthusiastically executed her role as guardian of her husband's creative life and, with his passing, strove to ensure his legacy as one of the leading American composers and musicians of the 20th century. In this and all business endeavors, Gail passionately advocated to establish clear definitions of intellectual property and copyright laws on behalf of not just her husband, but all artists.

"While she conducted intricate legal negotiations with corporations as grand dame of the Zappa Family Trust, she never failed to impart the sense of humor that was part and parcel of her indomitable and formidable personality. Gail, self-described as a pagan absurdist, was motivated by love in all aspects of her life, kept her authenticity intact, unbowed and, simply put, was one bad a** in the music business and political world.

"Gail will forever be identified as a key figure in the creative renaissance that is Laurel Canyon. But more than any singular accomplishment, she defined herself in her personal relationships, happiest when surrounded by loved ones and artists, often one in the same. The memories she leaves behind are indeed her own art form. Her searing intelligence, unforgettable smile, wild thicket of hair and trailing black velvets leave a blur in her wake."
