William “Bill” C. Leingang, 87, of Columbia, died Dec. 2, 2020, at Oak Hill Care Center, Waterloo. He was born Aug. 26, 1933, in Columbia, son of the late William A. and Mary E. (nee Toenjes) Leingang. He was married to Mary E. (nee Klein) Leingang, who survives him. They were married July 1, 1959, in Freeburg.

Bill had retired from the Federal Aviation Administration where he had worked as a supervisor. He was an active member of Immaculate Conception Parish, where he had served as a past school board member, 30+ year member of the men’s choir and had served the Knights of Columbus-Council 6165 as a treasurer. He had also been a member of American Legion Post 581. Bill’s family was always his passion and priority, and he never missed any of the grandkids’ sporting events as he was their greatest fan. He was an avid gardener and sold vegetables from the family farm for many years. Bill loved all things farming; tractors, barns and auctions.

Also surviving are his sons William (Theresa) Leingang of St. Louis, Robert (Rosemary) Leingang of Columbia and James (Andrea) Leingang of Chesterfield, Mo.; daughter Maria Leingang of Corpus Christi, Texas; grandchildren Elizabeth, Catherine, William B., Andrew, Nathanial, Alexandra, Sabrina, Noah and Owen Leingang; sisters Rita Hill of Freeburg, Marian (Reynold) Ledbetter of Columbia and Germaine (William) Schlueter of Webster Groves, Mo.; brother Paul (Jane) Leingang of Evansville, Ind.; along with other relatives and friends.

He was also preceded in death by his brothers-in-law Harry Hill, and John Klein.
