Thomas John Hayes

Thomas John Hayes of Canton died May 20, 2019. He was born in Boston on July 11, 1928 to Margaret (Cotter) and Eugene John Hayes, both natives of County Cork, Ireland. He graduated from Mission Church High School and entered the U.S. Marine Corps, where he proudly served at the end of World War II.

Under the GI Bill, he attended Boston College (the only school he applied to) and graduated in 1952 with high honors in physical chemistry. He went on to graduate school at the Massachusetts Institute of Technology where he was a Sloan Kettering Fellow in the chemistry department. In 1958, he began a 38-year career with the Hewlett Packard Company Medical Products Division where he worked on the development of many cutting edge medical instruments and played critical roles including helping develop a non-invasive pulse oximeter and many other innovative and highly technical monitoring devices.

After transferring to HP’s Marketing Department, Tom travelled the world introducing operating room physicians to many original instruments. While working at HP, he co-authored two medical texts: Capnography in Clinical Practice and Gas Monitoring in Clinical Practice.

Tom married “the girl across the street” (from Mission Hill) and the love of his life, Phyllis McManus, and they shared 57 years of loving marriage. Together, they raised seven highly accomplished children, of whom he was most proud.

His survivors include his beloved wife, Phyllis, and his much-loved children, Laurie Ann (Larry) Bogue, Julie (Dan) Jenkins, Brian Cotter (Linda), Paula Maureen (Bob) Holmberg, Patrice Marie (Tom) Wesner, Matthew Thomas (Amanda). Son Christopher Sean Esq., died of a cardiac arrest in 1995.

He was predeceased by sisters Mary Kelly and Virginia (Paul) Burke of Duxbury and brother-in-law Jim McManus, of Millis.
