He got the job at Central Perk the same way most people get jobs in LA: by having an unrelated skill nobody else had. Tyler was working as an actual barista when the crew put him behind the counter as the only background actor who could operate an espresso machine. He had no lines for 33 appearances. Then Marta Kauffman asked if he had acting experience, and 'Coffee Guy' became Gunther. The bleached hair was a coincidence. A friend practiced on his hair the night before his first shoot; the show loved it, and Tyler ended up bleaching his hair every week for a decade.
Gunther made him famous but didn't make him a movie star, and Tyler seemed to know it. After Friends wrapped in 2004, the substantial credits never materialized. He got a prostate cancer diagnosis in 2018 and said nothing publicly for three years, finally revealing it in June 2021, right after the Friends reunion aired. By then the cancer had spread to his spine, pandemic-era disruptions to his screenings letting the disease advance. He spent his final months on Prostate Cancer Foundation awareness work. That's a better obituary than most actors get.
Before he was a barista, Tyler was a geologist. He graduated from Clemson with a geology degree in 1984, joined the theater program there, and eventually got an MFA from the University of Georgia in 1987. He moved to LA to work in film editing, then picked up shifts at Guitar Center and the Bourgeois Pig coffee shop, the place that indirectly landed him on Friends. One detail that got lost in the Gunther mythology: despite spending a decade behind that espresso machine on set, he never actually made a single cup of coffee on the show.
Jennifer Aniston posted that 'Friends would not have been the same without you,' with David Schwimmer, Courteney Cox, and Matthew Perry adding their own tributes. Executive producer Kevin S. Bright called him 'an incredible person who spent his final days helping others.' A spoken word recording he made of Stephen Kalinich's poem 'If You Knew' became a Prostate Cancer Foundation awareness video.
