Hall died of heart failure at his home in Beverly Hills, California, on Saturday at the age of 96.
Born in Manitoba, Canada, Hall obtained a chemistry degree from the University of Manitoba. Hall hosted the show for 23 years until 1986, and for a short time in 1991.
Hall recalled in a 2013 interview that when the show began, audience members arrived buttoned down in formal suits and dresses.

But it was Hall who was lastingly identified as "TV's big dealer", as the show put it, something he found at least mildly disconcerting.
Hall was involved in Let's Make a Deal to the end, both an owner of the show and an occasional guest.
"In 1 percent of the cases, they didn't", Hall said. He was known for charity work for organizations including Variety Clubs International, which raised money for disadvantaged children.
He is survived by two daughters, a son, a brother and 5 grandchildren.
