LONDON – Carolyn Cassady, a writer who was married to Jack Kerouac’s traveling companion and a lover of the famous Beat author, has died in a hospital near her home in Bracknell, southeastern England. She was 90 years old.

She was married to Neal Cassady — a central character in the Beat generation and the basis of the character Dean Moriarty in Kerouac’s “On the Road” — for around 20 years. The couple had three children. She was also a close friend of Beat poet Allen Ginsberg.

She chronicled her experiences with the three in the memoir “Off the Road: My Years with Cassady, Kerouac and Ginsberg.” It was one of many attempts she made to correct what she saw as myths about the Beat Generation.

Carolyn Cassady first met the then-married Cassady, plus Kerouac and Ginsberg, while she was at the University of Denver getting a masters’ degree in fine arts and theater arts. The two married in 1948. They had three children and were married for 15 years.

She also had an affair with Kerouac — at Cassady’s urging, she said. In the 2011 documentary “Love Always, Carolyn,” she said it was “Neal’s wish to share me” with Kerouac. “I was against it, to begin with, but it was a survival for me to keep the man I loved.”
