One of the most recognizable voices in local radio has been silenced.

WBSM's Jack Peterson passed away Tuesday evening at Hathaway Manor in New Bedford at the age of 70 after a brief battle with pancreatic cancer.

For over 50 years, Jack, whose real name was Joel Polonsky, broadcast throughout Massachusetts, beginning his career as a disc jockey at WLLH in Lowell, and shifting to WNBH in 1980. It was there he earned the nickname "Captain Jack", serving as a morning show host for a number of years along with his wife, "First Mate" Lynne.

Jack garnered a reputation as a play-by-play announcer for local high school sports, calling the games of many area athletes throughout the years, and serving as master of ceremonies for the Otto Graham and Dave Cowens Achievement Awards.

Jack came to WBSM in 1998 as a morning drive newscaster, and became a beloved staple on the "Pete Braley Morning Show" until shortly before his death.

Jack enjoyed a lifelong love affair with baseball, and his favorite team, the Boston Red Sox. He also became known as an animal advocate, hosting the New Bedford Pet Fest for 15 years and helping a number of animals find their forever homes.

His wife, Lynne, wants to thank all of the friends and listeners who sent cards and well wishes to Jack during his illness.

Instead of a public funeral service, a celebration of Jack's life will be held and announced at a later date.
