In 1913, one of Tankstar USA Inc's subsidiaries, Schwerman Trucking Co, began business in Milwaukee WI. This year, Schwerman is marking its 90th anniversary.
The company has survived depressions, recessions, world wars, deregulation, as well as other catastrophic events, including the loss of its leader, Fred Schwerman, in 1982.
According to the company, its ability to change with the times and produce innovative ideas is one reason it survived nine decades.
