John Peter Medgyesy died peacefully on Nov. 2.

He was the esteemed husband of Carolyn Tilton Medgyesy with whom he had celebrated 65 years of marriage.

John was born on June 30, 1932 in Oak Park, Ill., to the late Helen Mayer Medgyesy and Laszlo Leopold Medgyesy. He spent his youth in Chicago and summers on the water sailing on Cedar Lake, Wisc.

He graduated from the Harris School in Chicago in 1949, MIT in 1953 and Harvard Business School in 1966.

He was an engineer in the Barrett Division of Allied Chemical & Dye Co. in Chicago, Reynolds Jamaica Mines Ltd. in Jamaica, West Indies and Metals & Controls in Attleboro, Massachusetts (acquired by Texas Instruments). He was a project engineer at the Checon Corporation in Attleboro. From 1967-1998 he was a co-owner and general manager of Matrix Incorporated from which he retired in August 1998.

John and Carolyn moved to Attleboro in 1957. He enjoyed many years of tennis at the Bearcroft Swim and Tennis Club and especially enjoyed his years of winter tennis at Turnpike Racquet Club in Plainville with an active, sociable group of friends. He was also involved with the City Republican Party. John valued his friends and enjoyed many trips to retreats in California and Utah, white water rafting down the Colorado River and salmon fishing in Iceland. He also enjoyed playing bridge. He will be remembered by all as a gentleman and a gentle man with a very dry sense of humor, a keen mind and a passion for classical music.

John, Carolyn and family enjoyed many summers at their vacation home on Martha’s Vineyard. Above all, family was most important to John, particularly his wife Carolyn, his children and grandchildren, nieces and nephews.

In addition to his wife, he is survived and will be deeply missed by his son John and his wife Rae; their sons, Peter and Steven; daughter Susan Grandin and her husband Preston. He was predeceased by his brother, L. Steven Medgyesy.

At the request of family, interment will be private.

Family and friends are invited to attend a celebration of John’s life at a memorial service to be held at a later date.
