John Robert Milligan, 75, of Jefferson, Iowa passed away at Mercy One Medical Center in Des Moines just before 1:00am on Friday, January 19, 2024. He was born on March 21, 1948, in Jefferson, Iowa to Robert and Dorothy (Swigert) Milligan. On August 3, 1969, he married the love of his life, Katherine (Hutchison) Milligan. They were married 54 wonderful years. John served in the US Army from 1969 to 1975 when he was honorably discharged. He earned his Professional Civil Engineering degree from Iowa State University. He consulted as an Engineer from 1971 - 1983. In 1983, he and 2 partners, Warder Hillhouse and Harold Fairbairn formed MHF Engineering. John was the City Engineer for Jefferson for 37 years while he was an owner of MHF. In 2018, the practice was sold and John retired. John will be greatly missed for his quick wit, dry humor, his patience and helpfulness to all who needed it. He was generous with his time and money towards projects and causes that were dear to his heart. He was a Rotarian for many years, receiving the Paul Harris Fellowship award 4 times. He also contributed to the polio plus program to eradicate polio worldwide. He received his pilot’s license in 1983. Although he hasn’t flown for a long time, he really enjoyed aviation. He loved all aspects of the outdoors - especially hunting, fishing and shooting muzzleloaders. He was an active member of Trinity Lutheran Church in Jefferson and the Raccoon Valley Muzzleloaders. Traveling and visiting historical sites were a favorite past-time of his. John could fix almost everything that was broken, if you were helping him, you knew everything had a place and it was expected to be put back in that manner. He was a tough “old-bird” beating so many serious medical ailments throughout his life.
