when was the zipper invented and by whom
Zipper The company, reorganized as the Fastener Manufacturing and Machine Company, moved to Hoboken, N.J. in 1901. Gideon Sundback, a Swedish-American electrical engineer, was hired to work for the company in 1906. Good technical skills and a marriage to the plant-manager's daughter Elvira Aronson led Sundback to the position of head designer. The company moved to Meadville, PA, where it operated for most of the 20th century under the name Talon, Inc. After his wife's death in 1911, Sundback devoted himself to improving the fastener, and by December 1913 he had designed the modern zipper. The rights to this invention were owned by the Meadville company (operating as the Hookless Fastener Co.), but Sundback retained non-U.S. rights and used these to set up in subsequent years the Canadian firm Lightning Fastner Co. in St. Catharines, Ont. Sundback's work with this firm has led to the common misperception that he was Canadian and that the zipper originated in that country.[7]
Toilet paper Joseph Gayetty is widely credited with being the inventor of modern commercially available toilet paper in the United States. Gayetty's paper, first introduced in 1857, was available as late as the 1920s. Gayetty's Medicated Paper was sold in packages of flat sheets, watermarked with the inventor's name. Original advertisements for the product used the tagline "The greatest necessity of the age! Gayetty's medicated paper for the water-closet."
