“I love you mom,” the 45-year-old actor posted on Facebook. “This morning, our beloved wife, mother, grandmother, matriarch and the exquisite artist, humanitarian, and champion for mental health, Anna PATTY DUKE Pearce, closed her eyes, quieted her pain and ascended to a beautiful place. We celebrate the infinite love and compassion she shared through her work and throughout her life.”
Sean added, “Her work endures…The Patty Duke Mental Health Project,” along with a link to a fundraising page. He posted an even longer tribute on the crowdfunding page.
