NOTE: Kiesha-George Washington Carver never invented peanut butter-that was an erronious myth-
According to the Corn Products Company, Dr. Ambrose Straub of St. Louis patented a peanut butter-making machine in 1903 and some unknown doctor invented peanut butter in 1890.
H. Kellogg, of cereal fame, secured US patent #580787 in 1897 for his "Process of Preparing Nutmeal," which produced a "pasty adhesive substance" that Kellogg called "nut-butter."Dr. John Harvey Kellogg patented a "Process of Preparing Nut Meal" in 1895 and used peanuts. Kellogg served the patients at his Battle Creek Sanitarium peanut butter. Joseph Lambert worked for Dr. Kellogg and began selling his own hand-operated peanut butter grinder in 1896. Almeeta Lambert published the first nut cookbook, "The Complete Guide to Nut Cookery" in 1899.
By 1914, many companies were making peanut butter.
Joseph L. Rosenfield invented a churning process that made smooth peanut butter smooth. In 1928, Rosenfield licensed his invention to the Pond Company, the makers of Peter Pan peanut butter. In 1932, Rosenfield began making his own brand of peanut butter called Skippy which included a crunchy style peanut butter.
Evidence of modern peanut butter comes from US patent #306727 issued to Marcellus Gilmore Edson of Montreal, Quebec in 1884, for a process of milling roasted peanuts between heated surfaces until the peanuts reached "a fluid or semi-fluid state." As the product cooled, it set into what Edson described as "a consistency like that of butter, lard, or ointment."
In 1890, George A. Bayle Jr., owner of a food business in St. Louis, manufactured peanut butter and sold it from barrels.
Agricultural chemist, George Washington Carver discovered three hundred uses for peanuts and hundreds more uses for soybeans, pecans and sweet potatoes. He started popularizing uses for peanut products including peanut butter paste(NOT TRUE PEANUT BUTTER), paper, ink, and oils beginning in 1880. The most famous of Carver's research took place after he arrived in Tuskeegee in 1896. However, Carver did not patent peanut butter paste(NOT TRUE PEANUT BUTTER) as he believed food products were all gifts from God. The 1880 date precedes all the above inventors except of course for the Incas, who were first. It was Carver who made peanuts a significant crop in the American South in the early 1900's.
Lea: most of the listed people were not inventors(created the products), but improved upon them.
Anonymous...::Dr. Christiaan Neethling Barnard (November 8, 1922 – September 2, 2001) was a WHITE South African cardiac surgeon, is famous for performing the world's first successful human-to-human heart transplant.
Chedvah and Lady V: Lewis Howard Latimer's talent for drafting and his creative genius led him to invent a new method of making carbon filaments for the Maxim electric incandescent lamp, not the light bulb and filament itself.
Dr. Charles Richard Drew, a very multi-talented physician ,did NOT invent the Blood Bank, but improved upon it.Contary to modern legend, he was not refused a transfusion by a hosptal for injuries in an auto accident when he fell asleep at the wheel-this is refuted by one of three other Black physicians riding with him.
The inaccuracies of all the inventor attributions is just incrdible-I don't have enough time to correct them.The above is only a sampling.VERIFY YOUR FACTS BEFORE YOU LOOK LIKE FOOLS.
