Daniel was born December 14, 1946 in Iowa City, the son of Lester and Lillian (McDermott) Callahan. He graduated from Dubuque Senior High School, and enlisted in the U.S. Navy. Daniel married Barbara Hall on July 25, 1970 in Peosta.

Buck was employed for the City of Dubuque in the Waste Water Treatment Facility for 37 years. He was an avid card player, and enjoyed “donating” to the casinos. Buck loved all sports, especially playing softball and watching the Yankees, Hawkeyes, and lots of ESPN. He enjoyed sitting outdoors and socializing with neighbors and friends.

Buck is survived by his wife, Barbara, of Dubuque; two children, Tina and Jean Callahan, both of North Liberty, IA; his sisters, Elaine Gansen of Peosta, Juanita Bakey, Becky (Terry) Lyons, and Debbie Callahan, all of Dubuque; his in-laws, Pat (Dorothy) Hall, Marlene Kalb, and Leo Roling, all of Graf; and many nieces and nephews.

Buck was preceded in death by his parents; his siblings, Kay (Willie) Reardon and Donald Callahan; and his in-laws, Mary Roling, Jack Kalb, Jerry Bakey, and Bill Gansen.

The family would like to express their thanks and appreciation to the University of Iowa Hospitals & Clinics.

My dad really lit up whenever Buck was around... in more ways than one! I don't remember Buck ever being around without hearing lots of laughter and happiness from my mom and dad. I am honored he was my Godfather, and hope he and dad and Jeep are enjoying their reunion.

Much love to Barb, Tina, and Jean. ❤️

I am very saddened at your loss; but we have great memories of softball games and the camaraderie the guys shared. Mike used to tell story upon story about his adventures, (or should we all them "misadventures") with Buck. Barb, hope you and the girls are doing OK. Jan Imhof
