Robert Glenn Johnson Jr. , better known as Junior Johnson, was an American professional stock car racing driver, engineer, and team owner as well as an entrepreneur. He won 50 NASCAR races in his career before retiring in 1966. In the 1970s and 1980s, he became a NASCAR racing team owner, winning the NASCAR championship with Cale Yarborough and Darrell Waltrip. He is credited as the first to use the drafting technique in stock car racing. He was nicknamed "The Last American Hero," and his autobiography and movie based on his upbringing is of the same name. In May 2007, Johnson teamed with Piedmont Distillers of Madison, North Carolina, to introduce the company's second moonshine product, called "Midnight Moon Moonshine", a nod to the days of his early youth in the 1940s when he made a living as a moonshiner/moonrunner and bootlegger.

Stock car racing is a form of automobile racing run on oval tracks and road courses measuring approximately 0.25 to 2.66 miles. It originally used production-model cars, hence the name "stock car", but is now run using cars specifically built for racing. It originated in the southern United States; its largest governing body is NASCAR. Its NASCAR Cup Series is the premier top-level series of professional stock car racing. Australia, Canada, New Zealand, Mexico, Brazil, Argentina, and the United Kingdom also have forms of stock car racing. Top-level races typically range between 200 and 600 miles in length.
