"The Survivor family has lost a legend. Rudy Boesch passed at the age of 91," Jeff Probst tweeted on Saturday.
"He played in the first season of Survivor at the age of 72. He is one (of) the most iconic and adored players of all time. And he served our country as a 45-year Navy SEAL. Rudy is a true American hero."
"Our hearts go out to Rudy's family and friends. He will be greatly missed," the reality show's official Twitter feed added.
People.com said the "Survivor" Season 1 fan favorite contestant died after a long battle with Alzheimer's disease.
Boesch was married to his wife Marjorie Thomas from 1955 until her death in 2008.
They had three children together.
