"Two routes by which Ostwald's efforts had an effect in America are interesting to trace. The earliest involved the well-known text, "Quantitative Chemical Analysis", by Albert B. Prescott and Otis C. Johnson of the University of Michigan, which went through a number of editions beginning in 1874. Prescott was one of the founders of the American Chemical Society and was its president in 1886. He is also reputed to have been the analyst who arrived at the figure of 99.44% for the purity of a common brand of soap. For the fifth edition of the book (1901) Eugene C. Sullivan (1872-1962), then a young instructor at Ann Arbor, was asked to prepare a section on Solution and Ionization according to Ostwald's ideas, which he did very well in about 4 pages. Sullivan had studied at Michigan, Göttingen, and Leipzig, receiving his PhD. under Ostwald in 1899 on trivalent iodine compounds. After teaching three years at Michigan, he was with the U.S. Geological Survey until 1908, when he went to the Corning Glass Works. There with W.C. Taylor he developed the low-expansion glasses later known under the brand name Pyrex, which did so much to simplify laboratory work."
