MERRIMACK, NH – John J. Walsh, 64, of Donovan Court, died Friday, March 20, 2015 in his home.

Born in Ipswich, MA on June 28, 1950, he was the eldest of four children of the late Thomas J. and Sophie (Aponas) Walsh. After graduating from Ipswich High School in 1968, he attended Northeastern University where he earned a Bachelor of Science degree in Biology.

Because of his interest in audio electronics, one of his part time jobs while in college was making deliveries for K & L Sound, a small stereo store. He eventually became a salesman there and after graduating college, joined the company full time. During his 15 years with the firm, he became K & L Sound’s advertising director and eventually, vice president of sales and marketing. At the time, K & L Sound was the largest single outlet consumer electronics store in New England. In 1998, John moved to New Hampshire and began working for ControlAir, Inc., a manufacturer of manual and electronic air regulators. His work centered around sales and technical support working with engineers to adapt ControlAir’s products to their requirements.

One of John’s great loves was music. It began while in high school as a member of the IHS band. Over the years, he amassed an extensive collection of LPs and CDs ranging from classical to rap and everything in between. He was also a voracious reader seldom being seen without a book in his hand. Another passion of his was basketball. He loved the Celtics and was a long-time season ticket holder.

He is survived by a sister, Christine Walsh Mitra of Ipswich; two brothers, James J. Walsh of Ipswich and Michael A. Walsh and his wife, Michelle of Newbury; two nephews, Thomas and Ryan Walsh; and a niece, Sophia Walsh, all of Newbury.

A memorial service will be held 11 a.m. Saturday, April 11 in the Whittier-Porter Funeral Home, 6 High St., Ipswich. Family and friends are respectfully welcomed. Interment will be private.
