Since news broke about Robin Williams' sudden passing, celebrities have been taking to social media to share their stories of how the late actor touched their lives.

In a Facebook post on Monday, Jessica Chastain explained how Williams' "generous spirit" changed her life.

"Robin Williams changed my life. He was a great actor and a generous person," she wrote. "Through a scholarship, he made it possible for me to graduate college. His generous spirit will forever inspire me to support others as he supported me. He will forever be missed."

The Oscar-nominated actress previously revealed that the scholarship she received to attend New York’s Juilliard School was funded by Williams, explaining that she was the first in her family to go to college.

"It paid for my schooling, back and forth to go home for Christmas, books, everything. He actually made it possible for me to go to school there because my family were not incredibly wealthy and I was the first one to go to college," she said.
