Jason Alexander

Jason Alexander is an American comedic actor, best known for his role as George Costanza on the NBC hit series Seinfeld.

Background
Alexander was born in Newark, New Jersey, the son of Ruth Minnie (née Simon), a nurse and health care administrator, and Alexander B. Greenspan, an accounting manager. He has a half-sister, Karen Van Horn, and a half-brother, Michael Greenspan. Alexander is a 1977 graduate of Livingston High School in Livingston, New Jersey. He attended Boston University but left the summer before his senior year, after getting work in New York City. He was later given an honorary degree in 1992. He is a keen magician, and only switched to acting as a career when he realized that he was unlikely to succeed as a magician.

Criminal Minds
Jason appeared as serial killer Henry Grace in the episode Masterpiece. Much to the surprise--and amusment--of his fans, he had long, flowing blonde hair.
