Nicky Katt, Boston Public Actor, Dead At 54; Cause Of Death Revealed By Family

Nicky Katt, whose TV and film credits include Boston Public and Dazed and Confused, has died. He was 54.

The news of Katt's death was confirmed Saturday by his attorney, John Sloss, to our sister site The Hollywood Reporter.

*UPDATE* Katt's sister Elise Ravenscroft revealed to Deadline Monday that the actor died by suicide.

"He died by suicide after battling with depression — one that he fought bravely but quietly," she said. "This is a pain no family should endure, yet far too many do. Mental illness is real, it is powerful and it is often invisible. We hope that by sharing this, we can help break the silence and stigma that so often surrounds mental health struggles."

On the TV side, Katt was best known for his role in Fox's drama series Boston Public, which ran from 2000-2004. He played geology teacher Harry Senate who taught kids in the "Dungeon." Katt ultimately exited the series during Season 3, after his character suffered a mental breakdown and took a leave of absence.

In addition to Boston Public, Katt appeared in Law & Order, The Guardian, Friends, Dear John, Father Murphy and Herbie, the Love Bug.

Katt was also known for his work on the big screen: In 1993, he played Clint Bruno in Dazed and Confused; in 2000, he played Greg Weinstein in Boiler Room and Obecks in The Way of the Gun; and in 2005, he played Stuka in Sin City.

His other film credits include Doom Generation, Strange Days, The Brave One, A Time to Kill and Batman & Robin.
