On what would have been his 65th birthday today, Zelda Williams remembered her father Robin Williams in a touching Instagram tribute. “Still not really sure what to do on days like today… I know I can’t give you a present anymore, but I guess that means I’ll just have to keep giving them in your name instead,” she captioned the photo. The late actor died by suicide in August 2014 at 63 years old after struggling with depression and anxiety, in addition to the early stages of Parkinson’s disease.

In the tribute, she explains how she helped three causes her father cared about—rescue dogs, people suffering from disabilities, and the nation’s wounded veterans—by donating to Freedom Service Dogs. According to their website, “Freedom Service Dogs is a nonprofit organization that enhances the lives of people with disabilities by rescuing dogs and custom training them for individual client needs.” Clients can include veterans and those currently serving with disabilities ranging from autism to multiple sclerosis and post-traumatic stress disorder.

Some of the charities that Williams supported included the Dream Foundation, Smile Train, the Bob Woodruff Foundation and Dogs Deserve Better, among others. As far as helping support the causes her father cared about, Zelda Williams said in her tribute, “Thought you’d get a kick out of furry, four legged friends helping change the world, one warrior in need at a time.”

Robin Williams was known for starring in many notable films, such as “Good Will Hunting,” “Mrs. Doubtfire,” “Aladdin,” “Dead Poets Society” and “Hook.” His daughter is currently starring in Freeform’s “Dead of Summer” and has previously won a BTVA People’s Choice Voice Acting Award for Breakthrough Voice Actor of the Year for her work in the television series “The Legend of Korra.”

She signed off her tribute with, “Happy birthday Poppo. Shasha, Zakky, Codeman and I all love you and miss you like crazy. Xo.”
