"Steve has a long list of earthly accomplishments," the actor's sons wrote. "He was known to the world as an brilliant and prolific actor and filmmaker, but to his family and many dear friends he was also a beloved husband, father and kind friend whose memory will always be a blessing."
"To truly honor him, do not cry for the loss of Stephen Furst. But rather, enjoy memories of all the times he made you snicker, laugh, or even snort to your own embarrassment," the message continued. "He intensely believed that laughter is the best therapy, and he would want us to practice that now. If you knew him personally, remember his gift for lighting up a room. And no matter who you are, when you think of Steve, instead of being sad, celebrate his life by watching one of his movies or use one of his bits to make someone else laugh - really, really hard."
Furst's friends and former co-stars took to Twitter to pay tribute to the late actor.
On behalf of everyone who worked on Babylon 5, Stephen Furst will be missed profoundly and everlastingly.
Furst's acting credits also included the National Lampoon spinoff Delta House, St. Elsewhere, The Dream Team, guest roles in Chips, The Jeffersons, Melrose Place and Chicago Hope. The actor was also a spokesperson for the American Diabetes Association.
