Benjamin HoltDied 5 Dec 1920 at age 71 (born 1 Jan 1849).American inventor of the crawler track (1904) in the form of an endless chain tread for his steam traction engine. The Caterpillar name resulted when a man photographing one of Holt's track-laying vehicles viewed the motion of the track as it travelled and said it reminded him of a caterpillar. Holt liked it as a nickname, and began using the name for his crawler track. Some years later, when his company merged with another manufacturer, Caterpillar was first used in the company name.
