Donald Glenn Garlits is an American race car driver and automotive engineer. Considered the father of drag racing, he is known as "Big Daddy" to drag racing fans around the world. A pioneer in the field of drag racing, he perfected the rear-engine Top Fuel dragster, an innovation motivated by the loss of part of his foot in a dragster accident. This design was notably safer since it put most of the fuel processing and rotating parts of the dragster behind the driver. The driver was placed in front of nearly all the mechanical components, thus protecting him and allowing him to activate a variety of safety equipment in the event of catastrophic mechanical failure or a fire. Garlits was an early promoter of the full-body, fire-resistant Nomex driving suit, complete with socks, gloves, and balaclava.

Drag racing is a type of motor racing in which automobiles or motorcycles compete, usually two at a time, to be first to cross a set finish line. The race follows a short, straight course from a standing start over a measured distance, most commonly 1⁄4 mi, with a shorter, 1,000 ft distance becoming increasingly popular, as it has become the standard for Top Fuel dragsters and Funny Cars, where some major bracket races and other sanctioning bodies have adopted it as the standard. The 1⁄8 mi is also popular in some circles. Electronic timing and speed sensing systems have been used to record race results since the 1960s.
