Born on August 29, 1929, in Sioux City, Iowa, Jim graduated from Trinity High School in 1947 before serving for two years in the US Army, where he achieved the rank of second lieutenant. After his service, he attended Creighton Law School, graduating in 1955 and being admitted to the practice of law the same year. Jim mainly focused his practice on workers' compensation law and was elected president of the Woodbury County Bar Association before his retirement in September of 1998. Even after retiring, Jim continued to serve as a mediator for workers' compensation cases for several years.
On November 27, 1965, Jim married Beverley (George) Cosgrove, and the couple remained together for over fifty-five years until Bev's passing in 2021. Jim was a devoted Catholic and was a member of Holy Cross Parish, also serving on the Diocesan Finance Council for over twenty years. Additionally, he was president of the Bishop Heelan Catholic High School Parent Board in 1987-88. Jim was also a lifelong fan of Notre Dame football and often traveled to South Bend to watch games, combining football games with trips to Ireland and Jacksonville, where he was joined by family members for camaraderie and Guinness.
Jim was an avid golfer and served as president of the Sioux City Boat Club from 1976-79. Despite losing some yardage on his drive, Jim played golf well into his eighties, using his deft touch around the green with an eight iron and a putter.
Jim is survived by his sister, Kay Mahoney; his two sons, Daniel (Laurie) and Steven (Renee); his five grandchildren, Connor, Kellen, Katie, Liam, and Oban; as well as numerous nieces and nephews. Jim was preceded in death by his parents, Frank and Mary (Knowles) Cosgrove, and his siblings, Suzanne Floeder, Patricia Steere, Joseph Cosgrove, Eugene Cosgrove, Barbara Sullivan, Lenore Cosgrove, and Fr.
