"Pat changed the trajectory of the fight against A.L.S. forever. He inspired millions to get involved and care about people who are living with A.L.S."

Calaneet Balas, president and chief executive of the ALS Association, in a statement following the death of Pat Quinn on Sunday at age 37, seven years after he learned he had amyotrophic lateral sclerosis (ALS). Quinn and his friend Pete Frates, who also had ALS, are “credited with amplifying” the Ice Bucket Challenge in the summer and fall of 2014. The challenge, in which people dumped buckets of ice water on their head, raised $220 million to fight ALS, according to the report in The New York Times, “Pat Quinn, Who Promoted A.L.S. Ice Bucket Challenge, Dies at 37.”
