This November is the 100th anniversary of the Armistice, the end of World War I. To mark the occasion, Project Archivist Emily Davis dug into the early history of the Mellon Institute of Industrial Research to highlight some of the work that was carried out there during World War I. Established in 1913, the Mellon Institute was roughly a year old when war broke out in Europe in 1914. That same year, it’s founder Robert Kennedy Duncan passed away at the age of 45, never to see his concept of the industrial research fellowship system flourish into a pioneering industrial research firm. By the time the United States became involved in World War I in 1917, scientists at the Mellon Institute had already been contributing to the war effort for several years.
