George Hovanec dropped out of school to work, then joined the Marine Corps, serving in a howitzer battalion in Guadalcanal and New Zealand.
Hovanec's family tell WTAE-TV ( http://bit.ly/LBCl4U) most of his relatives didn't know the family patriarch never graduated. So granddaughter Karen Murray approached Steel Valley High School administrators about a birthday surprise.
Hovanec says he's glad to finally get his diploma 67 years after he came home from World War II.
