Zoel J. Parenteau Jr., a key figure in two midwestern public TV stations, died Jan. 10, 2008, at age 75. Parenteau launched Kansas City’s pubTV station, then known as KCSD and operated by the public schools, in 1961. His title changed to g.m. and the call letters to KCPT when a separate nonprofit took charge later. In 1972, he moved to KPTS in Wichita, Kan., and managed it for 25 years.
