The downside of overdesign, Part 2: A Dunn history

Editor’s Note: This is a two-part series. Part 1 can be found here.

My father, John Edward Dunn, was a Foreman in the New York City Department of Bridges. His shop was in Brooklyn on Kent Avenue adjacent to the Brooklyn Navy Yard. His first assistant at that shop was a man named Connie Rank. Dad’s responsibilities were to oversee the maintenance and repairs of all of the smaller bridges in Brooklyn, Staten Island, and parts of Queens. The Mill Basin Bridge was one of his.

Dad was on call 24/7 in response to any bridge emergencies. At any time of day or night a phone call would come in and he would have to respond. When calls came in at 2 AM or 3 AM or whenever, the whole household would be awakened. Dad would answer the call and I would hear “Yeah. Okay, I’m on my way.” Then I’d hear Dad dialing a call where I’d hear “Connie? Yeah. See you there,” and that would be that. The routine was that familiar. Nothing further needed to be said. He wouldn’t get home again until at least 5:30 PM the following day for having responded to whatever emergency had occurred and then having worked a full day afterward without interruption.

Many of those emergencies were at the Mill Basin Bridge. One of them made the front page of a city newspaper. There was a full page photo of the bridge taken from ground level showing all kinds of emergency vehicles on the scene with all of their lights gleaming against the dark sky. Dad showed me that paper and asked “Do you see that little dot here?” I said “Yes,” and he said, “That little dot is me.” He knew where he had been standing.

Following one accident, perhaps it was the accident above, Dad apparently saved someone’s life. He was honored for that by Mayor Robert F. Wagner. Neither I at the age of twelve nor my sister at nine were ever told the details of the event, but it led to Dad shaking hands with the Mayor at New York City Hall.

John Dunn’s late father, John Edward Dunn, shaking hands with NYC mayor Robert F. Wagner circa 1956 to receive an award for his brave work saving a life as a foreman with the NYC Department of Bridges.

John Dunn is an electronics consultant, and a graduate of The Polytechnic Institute of Brooklyn (BSEE) and of New York University (MSEE).
