“As a lad he became expert as an amateur watchmaker. Disliking farm work because, “considering the results, there was too much work on the place,” he became an apprentice mechanic in Detroit, and repaired watches in a jewelry shop at night. He flirted with the idea of entering the watch manufacturing business on a large scale, “but I did not because I figured out that watches were not universal necessities.” His apprenticeship over, he served with the local representative of the Westinghouse Company, setting up and repairing their road engines.”
