Born in England, Abercrombie started out as a stage dancer and made his American stage debut in 1955 in a production of Stalag 17 with Jason Robards. After serving in the Army as part of Special Services in Germany, he returned to acting, appearing in numerous plays, TV shows and films before a seven-episode arc on Seinfeld changed his life."Incredibly so," he told CNN in 1998. "I mean, I have been around as an actor for 40-odd years, and this show knocked me out of the ballpark."Abercrombie played Justin Pitt, Elaine's eccentric, picky boss who fired her after he became convinced that she had tried to kill him. "I was a pain in the neck. I was a hypochondriac. I was many things, and I just made her life so miserable," Abercrombie said of Mr. Pitt. "She wouldn't take the salt off my pretzels, you know. She brought me white socks ... she did a lot of things for me, but she could never do it right."Abercrombie also appeared on the TV series Birds of Prey, Get Smart, L.A. Law, Dynasty, Northern Exposure, NewsRadio, Murphy Brown, Desperate Housewives and How I Met Your Mother. Most recently, he recurred on Wizards of Waverly Place as Professor Crumb.
