Bill Steinecke was a minor league manager for 22 years between 1937 and 1964, the first half as player/manager. He almost always managed in the low minors, and was for many years in the Milwaukee Braves chain. He is probably best known to readers of baseball literature as the manager of the 1959 McCook Braves, for whom Pat Jordan pitched (Phil Niekro and Elrod Hendricks were also on that team, among others). In Jordan's classic tale of disillusionment, A False Spring, "Steiny" comes across as a profane but endearing character.
Steinecke also scouted for the Montreal Expos in 1969.
