Aside from being the first woman to earn a PhD in Purdue's School of Engineering, Thomas was also the third person to receive a PhD in Industrial Engineering. With Purdue's own Lillian Gilbreth and Eleanor Clyme, Thomas would go on to publish numerous books on management, including Management in the Home: Happier Living Through Saving Time and Energy and Scientific Management in the Home: The Empress's New Clothes.
