New York lawyer and politician Matthew Hale and Southwick, to investigate a more humane means of execution. The commission members surveyed the history of execution and sent out a fact-finding questionnaire to government officials, lawyers, and medical experts all around the state asking for their opinion. A slight majority of respondents recommended hanging over electrocution, with a few instead recommending the abolition of capital punishment. The commission also contacted electrical experts, including Thomson-Houston Electric Company's Elihu Thomson (who recommended high voltage AC connected to the head and the spine) and the inventor Thomas Edison (who also recommended AC, as well as using a Westinghouse generator). They also attended electrocutions of dogs by George Fell who had worked with Southwick in the early 1880s experiments. Fell was conducting further experiments, electrocuting anesthetized vivisected dogs trying to discern exactly how electricity killed a subject. In 1888, the Commission recommended electrocution using Southwick's electric chair idea with metal conductors attached to the condemned person's head and feet. They further recommended that executions be handled by the state instead of the individual counties with three electric chairs set up at Auburn, Clinton, and Sing Sing prisons. A bill following these recommendations passed the legislature and was signed by Governor Hill on June 4, 1888, set to go into effect on January 1, 1889. The New York Medico-Legal Commission The bill itself contained no details on the type or amount of electricity that should be used and the New York Medico-Legal Society, an informal society composed of doctors and lawyers, was given the task of determining these factors. In September 1888, a committee was formed and recommended 3000 volts, although the type of electricity, direct current (DC) or alternating current (AC), was not determined, and since tests up to that point had been done on animals smaller than a human (dogs), some members were unsure that the lethality of AC had been conclusively proven. At this point the state's efforts to design the electric chair became intermixed with what has come to be known as the war of the currents, a competition between Thomas Edison's direct current power system and George Westinghouse's alternating current based system. The two companies had been competing commercially since 1886 and a series of events had turned it into an all-out media war in 1888. The committee head, neurologist Frederick Peterson, enlisted the services of Harold P. Brown as a
