Peter Holt is the great-grandson of Benjamin Holt, who developed the first practical track-type tractor 100 years ago. The Holt family’s history in San Antonio began in 1933, when Peter’s great uncle, William K. "Bill" Holt, moved to San Antonio to start a Caterpillar dealership. He had no heirs, so Bill invited B.D. Holt (Peter’s father) to get involved in the business. In 1961, B.D. Holt moved to Corpus Christi and started his own Caterpillar dealership.
