Those who knew former Travelers CEO Jay Fishman said they are in shock following his death.
Jay Fishman battled ALS for many years and became an advocate for the disease.
This year's Travelers Championship raised money for ALS research.
Brian Savo said he and Fishman were part of a fraternity that neither one of them chose.
Savo has also battled ALS and said Fishman's strength helped give him hope.
"People can tell you 'it's a hard disease, it's a rough disease', but until you're thrown in it personally and you see what the family, the friends or the person it's hard to comprehend how horrific and unforgiving this disease is," said Savo.
Fishman invited all of the ALS patients from special care to be part of the tournament.
Savo served as an honorary chairman.
"It was an amazing week and I'm very happy that I had the opportunity to be a part of his life," said Savo.
Fishman was described as being brave and still driven in the face of his illness.
"Jay was willing to put his resources and his face on the front lines and it takes a lot of courage. It's great to have a man like that on your side," said Savo.
The two last spoke at the closing ceremonies for the tournament. He said he was stunned to hear of Fishman's passing.
"Tough one to digest. [A] good man was lost today," said Savo.
He said Fishman's passing has been hard on many.
"For the ALS community and for his employees. A very, very special man, who touched a lot of hearts and he will be dearly missed," said Savo.
Savo had planned on reaching out to Fishman in the next few days to thank him for setting Savo up with a new doctor for ALS treatment.
