the Thomson-Houston Electric Company, to make sure the first electric chair was powered by a Westinghouse AC generator. Thomas Edison's staunch anti-AC tactics were not sitting well with his own stockholders. By the early 1890s, Edison's company was generating much smaller profits than its AC rivals, and the War of Currents would come to an end in 1892 with Edison forced out of controlling his own company. That year, the financier J.P. Morgan engineered a merger of Edison General Electric with Thomson-Houston that put the board of Thomson-Houston in charge of the new company called General Electric. General Electric now controlled three-quarters of the US electrical business and would compete with Westinghouse for the AC market. West Orange and Fort Myers (1886–1931) Edison moved from Menlo Park after the death of his first wife, Mary, in 1884, and purchased a home known as "Glenmont" in 1886 as a wedding gift for his second wife, Mina, in Llewellyn Park in West Orange, New Jersey. In 1885, Thomas Edison bought 13 acres of property in Fort Myers, Florida, for roughly $2,750 () and built what was later called Seminole Lodge as a winter retreat. The main house and guest house are representative of Italianate architecture and Queen Anne style architecture. The building materials were pre-cut in New England by the Kennebec Framing Company and the Stephen Nye Lumber Company of Fairfield Maine. The materials were then shipped down by boat and were constructed at a cost of $12,000 each, which included the cost of interior furnishings. Edison and Mina spent many winters at their home in Fort Myers, and Edison tried to find a domestic source of natural rubber. Due to the security concerns around World War I, Edison suggested forming a science and industry committee to provide advice and research to the US military, and he headed the Naval Consulting Board in 1915. Edison became concerned with America's reliance on foreign supply of rubber and was determined to find a native supply of rubber. Edison's work on rubber took place largely at his research laboratory in Fort Myers, which has been designated as a National Historic Chemical Landmark. The laboratory was built after Thomas Edison, Henry Ford, and Harvey Firestone pulled together $75,000 to form the Edison Botanical Research Corporation. Initially, only Ford and Firestone were to contribute funds to the project, while Edison did all the research. Edison, however, wished
