Wilhelm Normann : ウィキペディア英語版 | Wilhelm Normann
Wilhelm Normann (16 January 1870, Petershagen – 1 May 1939, 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. ==Early life and education== His father, Julius Normann, was the principal of the elementary school and ''Selekta'' in Petershagen. His mother was Luise Normann, née Siveke. Normann attended primary school from 31 March 1877. At Easter of his sixth grade he moved to the ''Friedrichs Gymnasium'' in Herford. After his father applied for a teacher's job at the municipal secondary school in Kreuznach, Wilhelm changed to the Royal Secondary School in Kreuznach. He passed his examinations and left school at the age of 18.
