Olivia Harrison | $300 Million

Olivia Harrison is a British-Mexican author, more famously known for being George Harrison’s wife than for being a successful writer. Don’t get us wrong, she had a pretty successful career with her publication. However, we can’t deny that her late husband offered her fame on an international scale. Olivia was working as an A&M Records secretary when she met former Beatle, George Harrison.

The couple married in 1978 and stayed together up until George’s death in 2001. She also co-produced Martin Scorsese’s documentary, George Harrison: Living In The Material World and David Leland’s Concert for George, which won a Grammy Award. The money she made from these productions was given to her husband’s Material World Charitable Foundation. She also established the Romanian Angel Appeal and The George Harrison Fund for UNICEF. All credit goes to Olivia for having such a big heart and continuing to make a difference with her husband’s legacy!
