Comedian and activist Barry Crimins has died, only a month after revealing on Twitter he had been diagnosed with cancer. He was 64. His wife Helen shared the sad news earlier today:

Crimmins was a vet of the Boston standup scene, and founded two clubs, Ding Ho and Stitches, in the '80s. In the '90s he revealed in his act that he had been raped as a child and became a tireless activist against child pornography. Bobcat Goldthwait made the acclaimed 2015 documentary, Call Me Lucky, about Barry and his life, and you can stream that on Netflix, Amazon and iTunes. Watch the trailer, along with video of his standup, below.

There has been an outpouring of tributes on social media from fellow comedians, musicians and more, including Judd Apatow, John Hodgman, Ted Leo, Patton Oswalt, Marc Maron, and Neko Case. Read some of those below.

Rest in peace, Barry. You will be missed.
