Jeff Conaway, known to Babylon 5 fans as the actor who portrayed Zack Allan, has passed away after fighting pneumonia and blood sepsis. He had been admitted to the hospital on May 11 after being found unconscious at his home. He never regained consciousness and life support measures were withdrawn on Thursday afternoon, May 26. He passed away on Friday morning, May 27.

In addition to his Babylon 5 role, Jeff was famous for playing Kenickie in the musical "Grease" both on film and on Broadway and for playing the part of Bobby Wheeler on the TV series "Taxi".

In 1997, Jeff told interviewer Joe Nazzaro:

I feel very fortunate about the work I've been able to do, and hopefully the next 20 or 30 years of my career, now that the beast inside is staying there, I'll be lucky enough to grab onto a couple more big projects. Most people are never in a hit, let alone something that will run forever. I'm going to be Kenickie and Bobby Wheeler and Zack Allen for the rest of my life, and it's kind of fun now when people start calling me Zack!'
