Alex Trebek, the Canadian-born host of Jeopardy!, died Sunday. He was 80.

The show’s Twitter account announced that Trebek died early in the morning surrounded by family and friends.

Trebek revealed in March 2019 that he’d been diagnosed with Stage 4 pancreatic cancer. The survival rate was low, he acknowledged in a video, but he vowed to fight the disease and keep working.

The sad news triggered a flood of tributes from fans, celebrities and politicians, as well as former contestants for the man from Sudbury, Ont.

Thousands of former contestants organized mass messages of support. One group put together a collage of their thumb prints, a reference to the format of the show in which they used their “buzzer fingers” to answer clues.

Trebek had two children with his wife, Jean Currivan.
