Velcro
De Mestral gave the name "Velcro", a portmanteau of the French words "velour" ("velvet") and "crochet" ("hook"), to his invention as well as his company, which continues to manufacture and market the fastening system.
Sellers family
William Sellers (1824–1905) founded Sellers and company, the leading machine tool company of the nineteenth century. As president of the Franklin Institute, he proposed a standard screw thread ("the Sellers screw thread") that has since been adopted throughout the world. He pioneered principles of scientific management and efficiency in cooperation with his chief engineer, Frederick Winslow Taylor (1856–1915). Dr. Coleman Sellers (1827–1907) was also a pioneer in mechanical engineering and a founder and president of the American Society of Mechanical Engineers. He founded the Engineering Department at the University of Pennsylvania and was first president of the Philadelphia Museum of Art and the University of the Arts. He was president and professor of mechanics at the Franklin Institute and at the Stephens Institute of Technology. Among his many patents were the Kinematoscope, a protean development in the history of film. As president of the Cataract Construction Company at Niagara Falls, he was decisive in the development of hydroelectric power and the adaption of the alternating current rather than direct current in North America.
