Robert "Bob" Bowie began his career at Thornton in 1930 under Ernest Woodbury as a teacher of mathematics and a football coach. He ended his career having presided over the largest expansion of Thornton since the turn of the century.
Immediately upon arriving at Thornton, Bowie endeared himself to TA football fans by compiling a 31-12-1 record over his five years as a coach.
Not only his students but also his fellow teachers admired Bowie. Even today TA teachers raised money yearly for a scholarship in his name.
During his tenure the Locke Building the Linnell Gymnasium, the Scamman Science Building and the Industrial Arts Building were constructed.
