Biography of Thomas W. Williamson

Thomas W. Williamson was born in Topeka, Kansas in 1887. He received his associate's degree from Pennsylvania School of Architecture, returned home, and started working for the Kansas State Architect, John F. Stanton. After a year with Stanton, Williamson opened his own practice, Thomas Williamson & Associates, in 1912.

As the firm grew and Victory H. Loebsack joined Williamson, the company changed the name to Williamson-Loebsack & Associates, with a staff of 46 architects, draftsmen, engineers, and other specialists. Williamson-Loebsack & Associates remains the longest-lasting architectural firm in Kansas, operating from 1912 until 1972. Two years after the firm closed, Thomas Williamson died.

Within the sixty years of practicing architecture, the firm produced over 1000 projects. Five of their buildings have made it on the National Register of Historical Places. The most iconic building that Williamson designed was Topeka High School in 1932.
