Bertrand Jean Gachot is a Belgian-French former racing driver. Gachot enjoyed some success in the junior formulae, winning titles in Formula Ford before progressing through Formula 3 and Formula 3000, reaching Formula One in 1989. After winning the 1991 24 Hours of Le Mans, Gachot was sentenced to 18 months in prison for an aggravated assault that had occurred the previous December. He was released after two months on appeal, but his enforced absence enabled Michael Schumacher to make his Grand Prix debut.

The 1991 24 Hours of Le Mans was the 59th Grand Prix of Endurance, and took place on 22 and 23 June 1991. It was also the fourth round of the 1991 FIA Sportscar World Championship season.
