Man Who Voiced Tony The Tiger Dies

Marshall passed away on April 26 at Santa Monica Hospital in California, reported the Los Angeles Times. He’d been suffering from esophageal cancer.

Marshall first voiced the Frosted Flakes catchphrase – “They’re grrrreat!” – for Kellogg’s in 1999. By 2005, he’d taken over Tony the Tiger voicing duties completely, replacing Thurl Ravenscroft in the job. Ravenscroft had given Tony the Tiger a voice since 1952.

“We are saddened by the loss of Lee Marshall. His talent and warmth helped bring Tony the Tiger to life and will always be fondly remembered," a spokesperson for Kellogg told The Huffington Post.

Prior to getting into voice-over work, Marshall had worked as a radio DJ, news anchor and sports broadcast, according to HuffPost. Using his unique vocal sound, he also worked in cartoons and as a ringside announcer in wrestling matches.

Marshall is survived by his wife, Judie, his son, his stepdaughter and a granddaughter.
