Michael O'Hare born 1952

Actor Michael O'Hare, born May 6, 1952, is probably best known for his role as Commander Jeffrey Sinclair on Babylon 5 with Claudia Christian, Jerry Doyle, Andrea Thompson, Bill Mumy, Richard Biggs and Mira Furlan.  He had to leave the show after the first season due to his battle with illness.  He passed away September 28, 2012 from a heart attack.

Richard Biggs born 1960

Richard Biggs, born March 18, 1960, was best known (by nerds like me) as Dr. Steven Franklin on Babylon 5.  He also appeared in an episode of Crusade, the mini-series spin-off.  Unfortunately, he left us too early.  Biggs passed away May 22, 2004 from an ascending aortic aneurysm.
