William S. Kaden died on Tuesday, Oct. 30 at Care Dimensions Hospice in Lincoln. He was 83.

Bill was born on Independence Day, July 4, 1935, and would relish in the parties and fireworks each year. He was a son of the late George J. and Anna Kaden. Born and raised in Dorchester, he was a graduate of Boston Latin High School and later served in the army. Bill graduated from Harvard University with a bachelor’s degree and earned his doctorate in medicine from Yale University where he was second in his class. Years later, he earned his master’s degree in business administration from Northeastern University. On July 25, 1970, he married Elizabeth H. Howe and they lived in Newton before making Weston and Edgartown their homes.

His career began at Harvard Health Services in Cambridge where he eventually headed its emergency department. He treated everything from avulsion fractures to acute narcotic withdrawal. Bill later became the medical director at Harvard’s Business School of Health Services. In 1975, while at Harvard, he spearheaded a new effort in establishing two coronary units on the 40-yard line at every football game. Bill realized time was a critical element for heart attack patients and the availability of defibrillators and medical personnel ensured lives being saved and it did.

In conjunction with his work at Harvard he maintained a private medical practice. Retirement from Harvard in 2001 led him to a position at MassPRO in which he reviewed medical reports. He served as its director and enjoyed full retirement in 2009.

When away from work, Bill loved riding his bike. He traveled throughout the world and explored on his bicycle. He also participated in numerous charity rides to raise awareness and funds. Bill also enjoyed a challenging game of chess, squash with colleagues, classical music and raising orchids. Not one to sit idle even in retirement, he always kept his mind active with games in trigonometry and math, crosswords and puzzles.

In addition to his wife of 48 years, Betsy, he is survived by his children, Felice A. Kaden-Laird of Bethesda, Md., Matthew A. Kaden of Miami, Fla. and Benjamin H. Kaden and Gregory O. Kaden of Weston; his sister Barbara Matorin of Newton; six grandchildren and nieces and nephews.

Family and friends gathered on Friday, Nov. 2 at the Wilson Chapel at Newton Theological Seminary at 1 p.m. Interment with military honors was in Weston.
