Cynthia Lennon, the first wife of John Lennon, died in Spain on Wednesday. The author was 75 and had cancer.

“Cynthia Lennon passed away today at her home in Mallorca, Spain, following a short but brave battle with cancer,” a message on her son Julian’s website read. “Her son Julian Lennon was at her bedside throughout. The family are thankful for your prayers. Please respect their privacy at this difficult time.”

Cynthia was born Cynthia Powell in Blackpool, England. She is best known for being the first wife of the famous Beatle. The two met at school in Liverpool in 1957 and were married in August 1962. The ceremony happened just before the Beatles became famous, the Guardian reports. When the Fab Four made their debut in America on “The Ed Sullivan Show,” John was introduced with the tagline, “Sorry, girls, he’s married.”

The two divorced in 1968 after Cynthia discovered Lennon's affair with Yoko Ono. They settled out of court and John agreed to give her £100,000 and custody of Julian, according to the Daily Mail.

Cynthia went on to be married three more times. Her longest marriage was her last. In 2002, she married Noel Charles and was with him until he died in 2013. Charles was also a victim of cancer.

Lennon's first wife wrote two books in her lifetime. In 1978, she released a memoir called "A Twist of Lennon" and in 2005, she published "John." Her son Julian wrote the foreword for the latter book. 

Julian, her only child, has expressed his grief on social media. He posted a tribute tweet to his mother and turned his personal website into a memorial.
