Louis B. Neumiller was known for his humility, integrity, and commitment to quality. As president of the Caterpillar Tractor Company from 1941-54, he led the manufacturer of earth-moving equipment through the challenges of World War II into global expansion. In the book In Their Time: The Greatest Business Leaders of the Twentieth Century, authors Mayo and Nohria describe Neumiller’s leadership as “success without fanfare.” His mark of greatness, they note, was that he took his identity out of the business and “let his company become a hero instead of himself.”
