## History

Caldwell Tanks was founded in 1887 by William E. Caldwell. The company was originally known as W.E. Caldwell Co. The firm remained in the Caldwell family until 1986 when it was purchased by James W. Robinson. Robinson appointed a former banker, Bernard S. Fineman, to be president of Caldwell.
The W.E. Caldwell Company headquarters was originally located on what is now part of the campus of the University of Louisville. The university's Red Barn multi-purpose activities facility is a remaining building of the original Caldwell Tanks complex. The university purchased the facility from Caldwell in 1969.
In April 2011, Caldwell Tanks completed a 16,000-square-foot (1,500 m$^2$) expansion of its headquarters in Louisville. The expanded space doubled the office space at its Louisville headquarters, adding additional offices, conference rooms, and file-storage rooms. Caldwell also announced plans for a 24,000-square-foot (2,200 m$^2$) addition to its 180,000-square-foot (17,000 m$^2$) production facility.
