The French physician and physicist Dr Jules Guyot (1807-1872) first studied medicine and then became a revolutionary politician. After spending time in prison as a result, he gave up politics and began to do scientific work on mechanics, physics and telegraphy. Among other things, he invented a new type of locomotive. He became intensively involved in viticulture and visited many French wine-growing regions. Based on these studies, he published his main work "Etudes des vignobles de France" (Studies of the Vineyards of France) in 1872.
His findings led to major changes in French viticulture. Around 1860, Guyot further developed a pruning system that had been known for some time and popularised it throughout the world. This form of Guyot training (low trellis training), the most frequently practised in European quality viticulture in many countries, was then named after him. He was also involved in fruit growing and a pear variety also bears his name. In his honour, the "Vigne et du Vin" institute at the University of Burgundy in Dijon was named after him.
