Robert Alan McIntosh Sr.

Feb 20, 2021

Robert Alan McIntosh Sr., 74, of Nashua passed away on Sunday, February 14, 2021 at his home surrounded by family. He was born on May 1, 1946 in Arlington, MA to the late Clarence “Red” McIntosh and Ruth (Keene) McIntosh. He was the loving husband of Constance J. (Krajewski) McIntosh for 53 years. They were high school sweethearts and married on August 5, 1967 at St. Patrick’s Church in Nashua.

Bob attended Nashua High School where he received his diploma in 1964. Following high school, he attended the University of New Hampshire where he received his Bachelor’s degree in Mechanical Engineering. He then attended Northeastern University in Boston, MA where he received his Master’s degree in business.  

He was employed at Kollsman (Elbit Systems) for 32 years until his retirement in 2017. While at Kollsman, he worked as a project engineer in the avionics department and later was an engineer for the KMC medical division. Bob was highly respected by his colleagues for his engineering knowledge and technical writing skills. He was a program engineer for writing work procedures for ISO 9000 and 9001. During his time at Kollsman he worked on numerous projects including the Bayer program, Kodak program, Learjet gulf stream program, CAPS program, and the night vision targeting system for the Cobra helicopter. While in the medical division at Kollsman he also worked on the blood analyzer program. Earlier in his engineering career he worked for Digital Equipment Corporation in Maynard, MA, Centronics in Hudson, NH and Santec.

Bob took great pride in maintaining his home, particularly his yard and gardens. He and his wife, Connie, always enjoyed day trips around New England. Their longest road trip was in 2018, after his retirement, when they traveled to Arizona for their nephew’s wedding. Bob enjoyed many years sailing on Winnipesaukee. He and his cousin Ed enjoyed studying landscape photography and taking windjammer cruises together. He was a voracious reader with particular interest in American History, shipwrecks, and stoic philosophy. He enjoyed riding his recumbent bike to work and enjoyed fishing and kayaking with his children and grandchildren at Lake Suncook.

Bob is best described as an extremely kind man with a calm personality and soft spoken voice. He never spoke ill of anyone and when conflict would arise between people, he always sought to help them find a way to get along, resolve differences and find acceptance. Above everything, family was most important to him. He always looked forward to his Friday night visits with his in-laws Bill and Jean discussing politics and how they were going to solve the problems of the world. He could always be relied on to listen to your worries or help you with your life projects. He always took pride in the accomplishments of his children and grandchildren, no matter how small and he always provided encouragement and support with their endeavors.

Besides his parents, he is predeceased by his infant daughter Kara Lynn McIntosh, his sister Susan C. Rioux, and brother in-law Ronald Thurston.

Survivors include his wife Constance J. (Krajewski) McIntosh of Nashua and their two children, Robert A. McIntosh Jr. of Nashua and Holly L. Pelletier and her husband John of Merrimack. He is also survived by his three grandchildren, Logan H. McIntosh of Nashua, Gunnar J. Pelletier, and Sydney K. Pelletier both of Merrimack; his sister Jane Santos and her husband Joseph, of Bridgewater, MA; his brother in-law Ronald Rioux of Nashua; his sister in-law Joanne “Cookie” Thurston of Houlton, ME; brother in-law Wayne Hill of Highland, CA; brother in-law Wilfred ” Bill” Hill and his wife Jean of Greenville; and brother in-law Theodore Krajewski of Nashua; as well as several nieces and nephews.
