“In a remarkable career, Sikking’s wonderfully exciting face gave us drama, comedy, tragedy and hilarious farce. His career spanned over six decades in television, film and on stage,” the late actor’s publicist, Cynthia Snyder, said in a statement. “His talent, integrity and imagination intrigued and delighted audiences.”

Neil Patrick Harris, who famously portrayed Sikking’s TV son Doogie Howser, took to Instagram Monday to pay his respects to his former co-star. “Jim Sikking played my dad in Doogie Howser, M.D. , and was one of the kindest, wisest, funniest and most generous people I’ve ever known,” the actor wrote . “A true professional. He treated everyone with respect, taught me countless lessons, yet always had a spark of mischief in his eyes. It was an absolute honor to be his son. My condolences to his actual family for their loss. #RIP”
