Oprah Winfrey
One of the richest and most powerful women in the world, the media mogul has, over the years, made generous contributions to various causes across the world. In 2018, she reportedly donated $100,000 to the Time’s Up campaign that seeks to empower women. That same year, she announced a $500,000 donation to March For Our Lives made by George and Amal Clooney. These were marches that took place across the U.S. in support of stricter gun control laws. When Hurricane Katrina struck, causing destruction to the Gulf Coast, Winfrey committed $10 million of her own money to help residents rebuild their homes. Through The Oprah Winfrey Leadership Academy for Girls, Winfrey spent an estimated $140 million over the past 10 years to keep the boarding school for underprivileged girls operational, she told Variety in 2017.
