Edward Herrmann, who portrayed Richard Gilmore on "Gilmore Star", passed away on Wednesday, 31 December, at a New York hospital.
He was suffering from brain tumour and was hospitalised for more than three weeks, according to his manager Robbie Kass.
"Having valiantly braved months of treatment for brain cancer, Edward Herrmann passed peacefully at 8.30am today at Sloan Kettering hospital in New York City," The Guradian quoted Kass as saying.
While informing the media about the death of onscreen Franklin D Roosevelt, the manager said that Herrmann was an accomplished actor, a scholar and a true gentleman with an incredibly kindness, stated CNN.
Meanwhile, Rory Herrmann described his father as a person with full of goodness, kindness and knowledge. According to him, "The Lost Boys" star wanted to share the beautiful things in life, reported New York Times.
"My friend Ed Herrmann was the kindest, classiest, most talented man. It was an honor and a joy to know him, a devastating blow to lose him," tweeted "Gilomore Girls" co-star Lauren Graham.
Born in Washington as the son of John Anthony Herrmann and Jean Eleanor, the legendary actor began his glamorous career from theatre.
Herrmann was recognised by the world for playing Franklin D Roosevelt in "Eleanor and Franklin" (1976) and "Eleanor and Franklin: The White House Years" (1977).
