Anderson Cooper remembers late mom Gloria Vanderbilt

Cooper's post reflected on the qualities that defined his mother, her perseverance, and her loving nature.

The touching tribute continued: "She is alive in my heart and in the hearts of all who knew her and loved her. She had an extraordinary and indomitable spirit, grit, determination, passion, and vulnerability.

"She experienced great love and horrific tragedies, but she never lost her almost childlike optimism; her openness to the world around her. She chose to remain vulnerable. Others would have closed off their hearts, protected themselves. My mom wanted to see and hear and feel everything....and that is exactly what she did. Bravo, Mom, Bravo."

Anderson Cooper is the son of Vanderbilt and her fourth husband, Wyatt Emory Cooper, who passed away in 1978.
