Charles Benjamin Dudley (July 14, 1842 - December 21, 1909) was a US chemist who was an early proponent of standardisation in industry.
Born Oxford, New York, Dudley's family circumstances demanded that he had to wait until 1867 before he could enter Yale College, supporting himself as a night editor on the New Haven Palladium newspaper. He eventually earned a Ph.D. from the Sheffield Scientific School.
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. He discovered emormous variation in the properties and quality of steel and the 1878 publication of his results1 caused 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 company and industry standards and demanded rigorous testing of materials to verify conformance. He developed a complete range of standards for the Pennsylvania Railroad including not just steel but also fuels, lubricants, paints and even locomotives.
In 1898, he was one of the founders of the American Society for Testing and Materials (ASTM).
He died in Altoona, Pennsylvania.
