Diesel founder renzo rosso began stitching jeans on a sewing machine at the age of fifteen. He used his mother's sewing machine to produce low-riding, bell bottomed jeans, which he would wear himself and sell to his friends for 3500 lira a piece. He later attended an industrial textile manufacturing high school in padua. In 1976 rosso began working for a clothing manufacturer called moltex, which was owned by adriano goldschmied. After working with the company for two years, he used a loan from his father to buy a 40% holding in the company, which changed its name to diesel, and marketed jeans under the diesel brand and many others. Rosso bought out goldschmied's interest in the diesel brand name in 1985 for us$500,000, becoming the sole owner of the company. Rosso has said that he learned marketing from the us, creativity from italy, and systems from germany
