James Sikking, who starred in series such as “Doogie Howser, M.D.” and “Hill Street Blues” died at the age of 90.
In a statement Sunday night, Sikking’s publicist, Cynthia Snyder, said the actor died of complications related to dementia.
Snyder told Fox News Digital: “Over the course of a remarkable career, Sikking’s wonderfully exciting face has given us drama, comedy, tragedy and hilarious farce. His career has spanned more than six decades in television, film and on stage.”
She added: “His talent, integrity and imagination have intrigued and delighted audiences.”

In “Doogie Howser, M.D.”, Sikking played Dr. David Howser, father of the show’s main character, played by Neil Patrick Harris.
Prior to that, he starred as Lt. Howard Hunter on “Hill Street Blues,” a Vietnam War veteran who led the Metropolitan Police Department’s Emergency Action Team.
Sikiking based his character’s uptight and eccentric nature on a drill instructor he had during basic training when his military service interrupted his time at the University of California, Los Angeles, from which he graduated in 1959.
“The instructor looked like he had hair made of steel and his uniform had so much starch in it that you knew it would stick to a corner when he took it off in the barracks,” he told the Fresno Bee in 2014.
