Titre: Eben Norton Horsford, American Scientist
Légende: Voir la traduction automatique
Eben Norton Horsford (July 27, 1818 - January 1, 1893) was an American scientist. He taught chemistry and conducted research at the Lawrence Scientific School at Harvard for 16 years, and published articles in major scientific publications on such topics as phosphates, condensed milk, fermentation, and emergency rations. He is best remembered today for reformulating baking powder. Previously, baking powder had contained baking soda and cream of tartar. He replaced the cream of tartar with the more reliable calcium biphosphate (also known as calcium acid phosphate and many other names). His development of baking powder was designated a National Historic Chemical Landmark in 2006. A generous supporter of higher education for women, he became president of the board of visitors of Wellesley College, and donated money for books, scientific apparatus, and a pension fund to the college. He became interested in visits to North America by Vikings, such as Leif Ericson, and was determined to prove that North America had been discovered not by a Mediterranean Catholic, but by an Aryan. He wrote a seemingly endless series of books, articles, and pamphlets about the Vikings' visits to Massachusetts. After his death, his daughter Cornelia took up the cause. Their work received little support from mainstream historians and archeologists at the time, and even less today. He died in 1893 at the age of 74.
