Experiments
As Brown was beginning his career as a salesman, Edison and his direct current system was competing with the Westinghouse electrical company, which used alternating current. Since Brown's work at the Brush Electric Company depended on DC, he became a leading critic of AC. In a June 1888 letter to the editor of the New York Post, Brown made his views loud and clear:.
The only excuse for the use of the fatal alternating current is that it saves the company operating it from spending a larger sum of money for the heavier copper wires which are required by the safe incandescent systems. That is, the public must submit to constant danger from sudden death, in order that a corporation may pay a little larger dividend.
A few years prior to Brown's article, New York State in 1886 established a committee to determine a new, more humane system of execution to replace hanging. Neither Edison nor Westinghouse wanted their electrical system to be chosen because they feared that consumers would not want the same type of electricity used to kill criminals in their homes. With Brown increasingly spearheading the claims about the dangers of AC, he also thought the claims could be used as cudgel against accepting the economic advantages of using AC for common consumption.
In order to prove that AC electricity was better for executions, Brown and Edison killed many animals, including a circus elephant (Topsy), while testing their prototypes. They also held executions of animals for the press in order to ensure that AC current was associated with electrocution. It was at these events that the term electrocution was coined. Most of their experiments were conducted at Edison's West Orange, New Jersey laboratory in 1888.
Though the campaign to discredit the alternating current system failed, the AC electric chair was adopted by the committee in 1889.

Famous quotes containing the word experiments:
“The trouble with tea is that originally it was quite a good drink. So a group of the most eminent British scientists put their heads together, and made complicated biological experiments to find a way of spoiling it. To the eternal glory of British science their labour bore fruit.”
—George Mikes (b. 1912)
“Science is a dynamic undertaking directed to lowering the degree of the empiricism involved in solving problems; or, if you prefer, science is a process of fabricating a web of interconnected concepts and conceptual schemes arising from experiments and observations and fruitful of further experiments and observations.”
—James Conant (18931978)
“The true thrift is always to spend on the higher plane; to invest and invest, with keener avarice, that he may spend in spiritual creation, and not in augmenting animal existence. Nor is the man enriched, in repeating the old experiments of animal sensation; nor unless through new powers and ascending pleasures he knows himself by the actual experience of higher good to be already on the way to the highest.”
—Ralph Waldo Emerson (18031882)
