Irwin Hasen, artist on Green Lantern, Justice Society, Flash, Johnny Thunder, creator of the character Wildcat with Bill Finger, and the newspaper strip Dondi, has died at the age of 96, reported by the New York Daily News.
Michael Uslan calls Hasen "DC's last surviving artist from World War II. So DC's 'Golden Age of Comics' has come to a close, 77 years after it began."
You can see a little of his legacy here. His strip Dondi about a war orphan, created with Gus Edson, ran from 1955 to 1986.
