G. H. Nichols and Company

In 1870, Nichols, assisted by Walter, started making acids. He attended the Brooklyn Polytechnic Institute when it was a prep school and worked at the institute laboratory for two years. Nichols later enrolled at Cornell University in the Science Department with the class of 1872, staying only for a few months. For a supposed participation in a prank, he was expelled from Cornell, refusing to divulge or acknowledge the names of his accomplices. Nichols then went to New York University, where he received his bachelor's degree in 1870, and his M.S. in 1873. His choice of career was attributed to, or influenced by John W. Draper, under whom he chose to study. Draper was considered an outstanding chemist who later became a founder of the American Chemical Society. In an interview conducted by Gerhard Hershfeld, Nichols revealed that the greatest characteristic of his father (George Henry Nichols) was his "bent for research." He also described his father George as a dreamer who was "always trying to figure out what the world would look like twenty years hence." During the 1870s, with the coming of the electrical age, Nichols put every bit of his ability and resources into producing high-grade copper on a large scale. Nichols was the first man in the chemical industry to use pyrite (the common sulphide of iron) in place of brimstone. According to Nichols in an interview, "the more he discovered, the more he found to discover, and the greater his business grew, the greater was his effort to make it grow." ==G. H. Nichols and Company and production==

In 1872, both Nichols and Walter, in order to expand their acid production to sulphuric acid and support their entrepreneurial needs, formed G. H. Nichols and Company, with the financial backing of William's father George Henry Nichols. Herreshoff invented and built a water-jacketed furnace and quickly became a partner in the company. ==Expansion and renovation==

During the 1880s, the company built and renovated a number of buildings, including two shops on the south side of the South Side Rail Road tracks (now the Lower Montauk Branch owned by and merged with the Long Island Rail Road), a building by Samuel Berg Strasser, and large additions to buildings on both sides of the railroad tracks; all of these structures were on the grounds of Laurel Hill/Newtown Creek. The reason for this was because these companies believed that pooling their resources would provide greater financial strength and enable them to effect economies in operation, while at the same time they permitted broader research and better service to their customers. Along with Nichols Copper Co., some of these companies included the Martin Kalbfleisch Co., Chappel Chemical Co., Jas. Irwin & Co., National Chemical Co., Dundee Chemical Co., Fairfield Chemical Co., and others. The plants of these component companies, located near the industrial centers of Philadelphia, New York, Pittsburgh, Buffalo, Cleveland, Chicago, St. Louis, and in eastern Canada, produced and offered 33 products: sulfuric acid was the most important, while other principal chemicals included muriatic, nitric, acetic, and hydrofluoric acids, sulfate of alumina and related alums, and sulfate of soda (crude salt cake and refined Glauber's salt). All of these materials involved the use of sulfuric acid as a raw material. ==Contracts and Phelps Dodge Corporation==

In an interview, Charles Walter Nichols (or C.W. Nichols) explained that the reason his father William Henry Nichols' business grew and became one of the largest and most successful in the country was because of Phelps Dodge with its huge copper volume. During the 1890s, the Nichols Copper Company (renamed from G.H. Nichols and Company in 1891) signed the first contract with Phelps Dodge, and since then around 90 percent of Laurel Hill's business came from Phelps Dodge. Problems these companies had to consider included transportation, distribution, and administration. In 1928, it was agreed that Nichols' capital would be increased and the stock issued to finance a proposed new plant in El Paso, Texas. All the new stock was taken by Phelps Dodge Corporation. In 1930, Dr. William Henry Nichols died; Phelps Dodge purchased the Laurel Hill Plant that same year. According to C.W. Nichols in his interview, Phelps Dodge took an active financial interest in 1937. The construction of the El Paso refinery was covered by Phelps Dodge and Calmat Arizona purchases of Nichols' Stock. ==Bankruptcy==

In February 1984, the company closed the El Paso refinery permanently due to high costs and changing markets. The plant's final products included copper, silver, gold, copper and nickel sulphates, and small amounts of selenium, tellurium, platinum, and palladium; the company had produced these materials throughout the twentieth century. The El Paso refinery was expected to fulfill the company's production needs. In September 1986, the company was sold to the United States Postal Service. Ten years later, the postal service sued the company in response to how they did not sufficiently clean up the site; the court then ordered the Phelps Dodge Corporation to buy back the property. Finally, in 2001, all buildings belonging to the company were torn down. ==References==
