Treat Williams, 'Everwood' and 'Hair' Actor, Dead at 71

Treat Williams has passed away.

The main star in teen drama Everwood died after being involved in a motorcycle accident, the actor’s longtime agent, Barry McPherson confirmed to PEOPLE. He was 71.

"He was killed this afternoon. He was making a left or a right [and] a car cut him off," McPherson said of his passing.

"I'm just devastated. He was the nicest guy. He was so talented,” he continued, adding, "He was an actor's actor. Filmmakers loved him. He's been the heart of the Hollywood since the late 1970s. He was really proud of his performance this year. He's been so happy with the work that I got him. He's had a balanced career."

The outlet notes that authorities have not confirmed Williams’ identity yet, however, Jacob Gribble, the fire chief for Dorset, Vermont, confirmed the crash happened around 5 p.m. on Monday on Route 30 by Long Trail Auto near Dorset, Vermont.

Gribble also noted that investigators believed the driver of the car did not see the motorcycle as he was turning. The unidentified motorcyclist was the only one hurt in the crash. A LifeNet helicopter arrived from Ticonderoga, New York, to airlift him to a hospital.

Williams’ lengthy career began in 1975 with the thriller Deadly Hero and spanned many roles and productions, including Hair, which earned him his first Golden Globe nomination, Prince of the City (which earned him another Golden Globe nomination), Once Upon a Time in America,  TV shows like Blue Bloods and Chesapeake Shores, and a number of Hallmark holiday projects.

But with over 100 acting credits to his name, his most beloved role was Dr. Andrew “Andy” Brown on The WB’s Everwood for four seasons, which turned him into TV's dad as he later appeared as Severide’s father on Chicago Fire and Neal Caffrey’s dad on White Collar.

This is the second memorable name from the coming-of-age drama to pass away this year as John Beasley—who played Irv Harper—died on May 31 after his health unexpectedly declined while he was undergoing testing on his liver. He was 79.

Williams is survived by his wife, actress Pam Van Sant, and their two children, Gill, 31, and Elinor, 25.
