George Segal, the Oscar-nominated actor known for his work in Who’s Afraid of Virginia WoolfJust Shoot MeThe Goldbergs, and more, died Tuesday of complications from bypass surgery, and tributes immediately came pouring in on social media.

“On behalf of everyone at the Goldberg’s we are devastated at the loss of our dear friend, George,” read a statement from the show. “He was kind, sweet, beyond talented and funny. George was the true epitome of class and he touched all of our lives so deeply. It was an honor and a privilege to have him as a colleague and friend all of these years. It is no surprise to any of us that knew him so well that he is a true national treasure. He will be missed by all. POPS, we will miss your banjo playing and your infectious laugh. Rest in peace.”

The Goldbergs creator Adam F. Goldberg, who cast Segal as the onscreen version of his grandfather, shared some of his favorite photos of Segal on Twitter. “Today we lost a legend,” he wrote. “It was a true honor being a small part of George Segal’s amazing legacy. By pure fate, I ended up casting the perfect person to play Pops. Just like my grandfather, George was a kid at heart with a magical spark. I think these memories say it all…”
