In 1875, he became a chemist for the Pennsylvania Railroad and started to investigate the chemical composition and metallurgical structure of rail tracks, breakage being a major hazard at that time.[2] He discovered enormous variation in the properties and quality of steel and the 1878 publication of his results[4] caused an uproar in the steel industry, who saw it as their sole domain to determine the quality of their products for sale. Dudley championed the development of the company and industry standards and demanded rigorous testing of materials to verify conformity. He developed a complete range of standards for the Pennsylvania Railroad, not only for steel, but also for fuels, lubricants, paints, and even locomotives.[2]
