Wilhelm Normann

Wilhelm Normann (16 January 1870, in Petershagen – 1 May 1939, in Chemnitz) (sometimes also spelled Norman) was a German chemist who introduced the hydrogenation of fats in 1901, creating what later became known as trans fats. This invention, protected by German patent 141,029 in 1902, had a profound influence on the production of margarine and vegetable shortening.
