Holder of 88 U.S. patents – with inventions including ‘reflective traffic eyes’

David E. Ross received a bachelor’s degree in mechanical engineering in 1893. Remaining deeply connected to his hometown of Lafayette, Indiana, Ross began his entrepreneurial journey in 1905 when he earned three patents for innovative work in automotive gears. Establishing Ross Gear and Tool Company in 1906, he quickly became a key supplier to industries like trucking, racing and yachting. In 1919, Ross founded Fairfield Manufacturing to specialize in differential gears, while Ross Gear and Tool focused on steering gears, demonstrating his strategic vision and commitment to excellence. With 88 U.S. patents, Ross is known particularly for inventing “reflective traffic eyes.” Beyond his business ventures, Ross played a key role in shaping Purdue's trajectory. His appointment to the Purdue Board of Trustees in 1921 marked the start of transformative initiatives, including development of a new football stadium dedicated to him and trustee George Ade in 1924. Ross’ tenure as president of the Board of Trustees brought significant advancements, such as those involving the Purdue Research Foundation, Purdue University Airport, and civil engineering camp – all made possible by his generous land donations. Ross' profound impact on Purdue's growth and development was recognized upon his passing in 1943. He was laid to rest on Slayter Hill, overlooking the campus he cherished, in a poignant tribute to his legacy and commitment to Purdue.
