Short answers, pulled from the story.
Linda McCartney (1941-1998) was an American photographer, musician, cookbook author, and animal rights activist. She was the first woman to place a photograph on the cover of Rolling Stone magazine, an unofficial house photographer at the Fillmore East in New York, a keyboardist in the band Wings alongside her husband Paul McCartney, and founder of the vegetarian food company Linda McCartney Foods.
Linda began photography as a hobby while studying fine arts at the University of Arizona, working with a Leica camera under instructor Hazel Larsen Archer. She got her break when she volunteered to photograph the Rolling Stones for Town & Country magazine at a record promotion party on a yacht in the mid-1960s. She became the unofficial house photographer at Bill Graham's Fillmore East concert hall, photographing artists including Jimi Hendrix, Aretha Franklin, and Bob Dylan.
Linda McCartney was the keyboardist and harmony vocalist in Wings, which she and Paul McCartney formed in 1971 after recording the album Ram together. Paul had taught her to play keyboards after the Beatles broke up in 1970. She continued playing alongside Paul after Wings disbanded in 1981, through The New World Tour in 1993.
Linda McCartney wrote two vegetarian cookbooks. The first, Linda McCartney's Home Cooking, was released in 1989, crediting author Peter Cox for his help and research. The second, Linda's Kitchen: Simple and Inspiring Recipes for Meatless Meals, was published in 1995 and was nominated for a James Beard Foundation Award in the Vegetarian Books category in 1996.
Linda McCartney died from breast cancer on the 17th of April 1998, at the McCartney family ranch in Tucson, Arizona, at the age of 56. She had been diagnosed in 1995 and the cancer spread to her liver. A memorial service at St. Martin-in-the-Fields in London drew 700 people including George Harrison, Ringo Starr, Elton John, and Billy Joel. Paul McCartney donated in excess of $2,000,000 for cancer research in January 2000, and a cancer clinic called The Linda McCartney Centre opened at The Royal Liverpool University Hospital in 2000.
