Born in 1947 in Glendale, Califorinia, Allwine was active on stage and screen most of his life, making his first television appearance at age 7 as one of the children interviewed by Art Linkletter on his HOUSE PARTY program. While still in high school, he formed his own acoustic music group, The International Singers, which performed in clubs and colleges all over the state. He went on to record with such singers as Dobie Gray and Bobby Vinton, and was a member of The Arrows, a musical group put together by Mike Curb.

In 1966, Allwine opted for a "normal" lifestyle and took a job in the mail room at The Walt Disney Studios. From there, he worked briefly in Wardrobe, then moved to Audio Post Production and began a 7-1/2 year stint under resident sound effects expert Jimmy Macdonald.

Allwine worked in sound effects editing on Disney films and television shows including SPLASH (1984), and THREE MEN AND A BABY (1987), as well as INNERSPACE (1987), ALIEN NATION (1988), and STAR TREK V: THE FINAL FRONTIER (1989) for other studios.

He received the Emmy Award and the Golden Reel Award for his contributions to Steven Spielberg's AMAZING STORIES, which he worked on for two years, and a second Golden Reel for his work on THE GREAT MOUSE DETECTIVE (1986).

For the past twenty years, Allwine was married to Russi Taylor, the voice of Minnie Mouse and many other popular characters for Disney, THE SIMPSONS, etc. They had their own production company, Taylor-Allwine Associates. Allwine and Taylor were both named Disney Legends in 2008 by The Walt Disney Company, and were immortalized with bronze plaque handprints at the Studio's Legends Plaza in Burbank.

Allwine is survived by Taylor and five children from previous marriages: Erin, Alison, Peter, Christopher, and Joshua; and a grandson, Isaac. Funeral services will be private. Details regarding a life celebration will be announced at a later date. In Allwine's memory, flowers or toys can be sent in Mickey's name to Mattel Children's Hospital UCLA, or donations can be made to such children's charities as the Elizabeth Glaser Pediatric AIDS Foundation, Guide Dogs of America, or St. Jude Children's Research Hospital.
