John L. Collyer
In 1940, Collyer brought to market the first tire with a substantial man-made rubber content. Goodrich’s tire was 50% synthetic rubber at a time when man-made rubber was not yet cost competitive with crude rubber. However, shortly thereafter, with the outbreak of World War II, the nation was cut off from its crude rubber sources. Summoned by the nation, Collyer developed and executed a program to provide the armed forces and the country with critical man-made rubber products.
