Theodore Hanneman Jr.

Theodore Daniel (Dan) Hanneman Jr. of Oklahoma City passed away April 15, 2019. Dan was born in El Reno on March 23, 1936, to Ted Sr. and Ida (Menz) Hanneman.

He and his nine siblings were raised on a farm west of El Reno. Dan graduated from El Reno High School. After serving in the U.S. Army from 1957-1959, Dan returned to Oklahoma and began working for Southwestern Bell Telephone and later retired from AT&T.

Dan married R. Ann Perkins on Aug. 31, 1963. Together they had three children: Theodore III (Teddy), Angela and David. Dan was a loving and hardworking father. He was actively involved in his children’s lives and was a Little League baseball coach, a Scoutmaster and an avid ballet supporter.

Later in life, his greatest joys came from watching his grandkids participate in baseball, softball, ballet and football. Dan enjoyed fishing, hunting and doing odd handyman projects. He was regularly known for being in his garage and “piddling” for hours. Dan was an active member of St. Patrick’s Catholic Church in Oklahoma City.

Dan was preceded in death by his loving wife, Ann (who died Sept. 24, 1984); his son, Teddy (who died in infancy); his father, Ted, and his mother, Ida; brothers, Ralph, Lester, Joe, August and Paul; and sisters, Theresa Ninman and Martha Griggs.

Dan is survived by his daughter, Angela Mathews and husband, Tony of Lee’s Summit, Mo.; his son, David Hanneman and wife, Michelle of Oklahoma City; and three grandkids, Brandon Hanneman, Courtney Mathews and Daniel Mathews. Dan is also survived by his brother, Earl, and sister, Mary Lou; and by a multitude of loving nieces and nephews.
