Toni Morrison, iconic author and the first African-American woman to win a Nobel prize, passed away at age 88.

Before her passing, Morrison, born in Ohio on February 18, 1931, was regarded as one of the most prolific authors of all time. The Howard University graduate is known for critically-acclaimed works of literature on the black experience including “Beloved,” “Song of Solomon” and “Sula.”

According to Celebrity Net Worth, Morrison was worth $20 million. The site reports most of her wealth was obtained through her many highly-regarded novels and co-writing children’s’ books with her son, Slade. Check out a few of her best sellers below.
