John J. Mohr, 1926–2023

John Jacob Mohr of Lincoln passed away on May 8, 2023 at the age of 96. Affectionately known as Jack, Dad and Pop-Pop, he was born in Lima Ohio on June 24, 1926. 

Jack grew up in an apartment with his mother above the Renz family bakery, in the building his grandfather owned. He got started with both photography and wood working at an early age. And after serving in World War II, he went on to college, graduating from MIT in 1950. It was while at MIT that he met Jean Field. They were married in the fall of 1950. Spending most of his career at Polaroid, he helped design and manufacture the Swinger, Big Swinger, and the SX70.

All who knew Jack will miss him terribly. But we know that he is now back together with his wife and in God’s care. He is survived by daughters Bonnie and Heather, her husband Paul, and grandsons Robert and John.

Jack was laid to rest in a private service on May 12, 2023 with U.S. Army military honors at the Lincoln Cemetery. Donations in his memory may be made to: Memorial Congregation Church of Sudbury, MA, The North Bennett Street School of Boston, MA, and MIT, Cambridge, MA.
