Garry Shandling, the co-creator and star of the ’90s HBO sitcom The Larry Sanders Show, died Thursday after a medical emergency. He was 66 years old.

The late comedian inspired an entire generation of comics — many of whom paid tribute to Shandling online as news of his death spread through the afternoon.

“Garry was a guiding voice of comedy. He set the standard and we’re all still trying to meet it. He gave us all opportunities to learn how to do the best work of our lives,” Larry Sanders costar Bob Odenkirk said in a statement. “But, more importantly, as I knew him these last few years, he was a person who never stopped trying to be a better person. That’s yet another way he inspired me and I’m sure many others who knew him.”

Among those mourning Shandling online included Amy Schumer, Steve Martin, Ricky Gervais, and Margaret Cho, as well as talk-show hosts Jimmy Kimmel and Seth Meyers, among others. See their tweets below.
