Edison designed his utility to compete with the then established gas lighting utilities, basing it on a relatively low volt direct current supply to power a high resistance incandescent lamp he had invented for the system.

Edison direct current systems would be sold to cities throughout the United States, making it a standard with Edison controlling all technical development and holding all the key patents.

Direct-current systems could be directly used with storage batteries, providing valuable load-leveling and backup power during interruptions of generator operation.

Direct-current generators could be easily paralleled, allowing economical operation by using smaller machines during periods of light load and improving reliability.

Edison had invented a meter to allow customers to be billed for energy proportional to consumption, but this meter worked only with direct current.

Direct current also worked well with electric motors, an advantage DC held throughout the s. The primary drawback with the Edison direct current system was that it ran at volts from generation to its final destination giving it a relatively short useful transmission range: to keep the size of the expensive copper conductors down generating plants had to be situated in the middle of population centers and could only supply customers less than a mile from the plant.

Starting in the s alternating current gained its key advantage over direct current with the development of functional transformers that allowed the voltage to be "stepped up" to much higher transmission voltages and then dropped down to a lower end user voltage for business and residential use.

Using induction coils to transfer power between electrical circuits had been around for 40 years with Pavel Yablochkov using them in his lighting system in and Lucien Gaulard and John Dixon Gibbs using the principle to create a "step down" transformer in , but the design was not very efficient.

In North America the inventor and entrepreneur George Westinghouse entered the electric lighting business in when he started to develop a DC system and hired William Stanley, Jr.

Westinghouse became aware of the new European transformer based AC systems in when he read about them in the UK technical journal Engineering.

Westinghouse saw a way to build a truly competitive system instead of simply building another barely competitive DC lighting system using patents just different enough to get around the Edison patents.

Westinghouse purchased the US patents rights to the Gaulard-Gibbs transformer and imported several of those as well as Siemens AC generators to begin experimenting with an AC-based lighting system in Pittsburgh.

The Westinghouse Electric Company was formed at the beginning of In March Stanley, with Westinghouse's backing, installed the first multiple-voltage AC power system, a demonstration incandescent lighting system, in Great Barrington, Massachusetts.

By the end of Westinghouse had 68 alternating current power stations to Edison's DC-based stations.

All of the companies had their own electric power systems, arc lighting systems, and even incandescent lamp designs for domestic lighting, leading to constant lawsuits and patent battles between themselves and with Edison.

Elihu Thomson of Thomson-Houston was concerned about AC safety and put a great deal of effort into developing a lightning arrestor for high-tension power lines as well as a magnetic blowout switch that could shut the system down in a power surge, a safety feature the Westinghouse system did not have.

He also thought the idea of using AC lighting in residential homes was too dangerous and had the company hold back on that type of installation until a safer transformer could be developed.

Due to the hazards presented by high voltage electrical lines most European cities and the city of Chicago in the US required them to be buried underground.

Besides being an eyesore , New Yorkers were annoyed when a large March snowstorm the Great Blizzard of tore down a large number of the lines, cutting off utilities in the city.

This spurred on the idea of having these lines moved underground but it was stopped by a court injunction obtained by Western Union.

Legislation to give all the utilities 90 days to move their lines into underground conduits supplied by the city was slowly making its way through the government but that was also being fought in court by the United States Illuminating Company, who claimed their AC lines were perfectly safe.

As AC systems continued to spread into territories covered by DC systems, with the companies seeming to impinge on Edison patents including incandescent lighting, things got worse for the company.

The price of copper was rising, adding to the expense of Edison's low voltage DC system, which required much heavier copper wires than higher voltage AC systems.

Thomas Edison's own colleagues and engineers were trying to get him to consider AC. Edison's sales force was continually losing bids in municipalities that opted for cheaper AC systems [35] and Edison Electric Illuminating Company president Edward Hibberd Johnson pointed out that if the company stuck with an all DC system it would not be able to do business in small towns and even mid-sized cities.

After Westinghouse installed his first large scale system, Edison wrote in a November private letter to Edward Johnson, " Just as certain as death Westinghouse will kill a customer within six months after he puts in a system of any size, He has got a new thing and it will require a great deal of experimenting to get it working practically.

He noted what he saw as inefficiencies and that, combined with the capital costs in trying to finance very large generating plants, led him to believe there would be very little cost savings in an AC venture.

In February Edison Electric president Edward Johnson published an page pamphlet titled " A Warning from the Edison Electric Light Company " and sent it to newspapers and to companies that had purchased or were planning to purchase electrical equipment from Edison competitors, including Westinghouse and Thomson-Houston, stating that the competitors were infringing on Edison's incandescent light and other electrical patents.

The pamphlet also emphasized the safety and efficiency of direct current, with the claim DC had not caused a single death, and included newspaper stories of accidental electrocutions caused by alternating current.

As arc lighting systems spread so did stories of how the high voltages involved were killing people, usually unwary linemen, a strange new phenomenon that seemed to instantaneously strike a victim dead.

Southwick to seek some application for the curious phenomenon. Fell and the Buffalo ASPCA, electrocuting hundreds of stray dogs, to come up with a method to euthanize animals via electricity.

An commission appointed by New York governor David B. Hill , which including Southwick, recommended in that executions be carried out by electricity using the electric chair.

There were early indications that this new form of execution would become mixed up with the war of currents. As part of their fact-finding , the commission sent out surveys to hundreds of experts on law and medicine, seeking their opinions, as well as contacting electrical experts, including Elihu Thomson and Thomas Edison.

After further prompting, Edison hit out at his chief electric power competitor, George Westinghouse, in what may have been the opening salvo in the war of currents, stating in a December letter to Southwick that it would be best to use current generated by "'alternating machines,' manufactured principally in this country by Geo.

As the number of deaths attributed to high voltage lighting around the country continued to mount, a cluster of deaths in New York City in the spring of related to AC arc lighting set off a media frenzy against the "deadly arc-lighting current" [52] and the seemingly callous lighting companies that used it.

The press in New York seemed to switch overnight from stories about electric lights vs gas lighting to "death by wire" incidents, with each new report seeming to fan public resentment against high voltage AC and the dangerously tangled overhead electrical wires in the city.

At this point an electrical engineer named Harold P. Brown , who at that time seemed to have no connection to the Edison company, [55] sent a June 5, letter to the editor of the New York Post claiming the root of the problem was the alternating current AC system being used.

Brown argued that the AC system was inherently dangerous and "damnable" and asked why the "public must submit to constant danger from sudden death" just so utilities could use a cheaper AC system.

At the beginning of attacks on AC, Westinghouse, in a June 7, letter, tried to defuse the situation. He invited Edison to visit him in Pittsburgh and said "I believe there has been a systemic attempt on the part of some people to do a great deal of mischief and create as great a difference as possible between the Edison Company and The Westinghouse Electric Co.

Edison thanked him but said "My laboratory work consumes the whole of my time". On June 8, Brown was lobbying in person before the New York Board of Electrical Control, asking that his letter to the paper be read into the meeting's record and demanding severe regulations on AC including limiting power to volts, a level that would make AC next to useless for transmission.

There were many rebuttals to Brown's claims in the newspapers and letters to the board, with people pointing out he was showing no scientific evidence that AC was more dangerous than DC.

Westinghouse pointed out in letters to various newspapers the number of fires caused by DC equipment and suggested that Brown was obviously being controlled by Edison, something Brown continually denied.

At a July meeting Board of Electrical Control, Brown's criticisms of AC and even his knowledge of electricity was challenged by other electrical engineers, some of whom worked for Westinghouse.

At this meeting, supporters of AC provided anecdotal stories from electricians on how they had survived shocks from AC at voltages up to volts and argued that DC was the more dangerous of the two.

Brown, determined to prove alternating current was more dangerous than direct current, at some point contacted Thomas Edison to see if he could make use of equipment to conduct experiments.

Edison immediately offered to assist Brown in his crusade against AC companies. Brown paid local children to collect stray dogs off the street for his experiments with direct and alternating current.

Brown then applied volts of alternating current which killed the dog. Four days later he held a second demonstration to answer critics' claims that the DC probably weakened the dog before it died.

In this second demonstration, three dogs were killed in quick succession with volts of AC. Brown's campaign to restrict AC to volts went nowhere but legislation did come close to passing in Ohio and Virginia.

What brought Brown to the forefront of the debate over AC and his motives remain unclear, [55] but historians note there grew to be some form of collusion between the Edison company and Brown.

Hastings who came up with the idea of using Brown and several New York physicians to attack Westinghouse and the other AC companies in retaliation for what Hastings thought were unscrupulous bids by Westinghouse for lighting contracts in Denver and Minneapolis.

During this period Westinghouse continued to pour money and engineering resources into the goal of building a completely integrated AC system.

He bought the Waterhouse Electric Light Company in and the United States Illuminating Company in , giving Westinghouse their own arc lighting systems as well as control over all the major incandescent lamp patents not controlled by Edison.

Shallenberger developed an induction meter that used a rotating magnetic field for measuring alternating current giving the company a way to calculate how much electricity a customer used.

Morgan to take over Westinghouse Electric. Thomson-Houston was continuing to expand, buying seven smaller electric companies including a purchase of the Brush Electric Company in Several of the business deals between Thomson-Houston and Westinghouse fell apart and in April a judge rolled back part of Westinghouse's original Gaulard Gibbs patent, stating it only covered transformers linked in series.

Morgan and the Vanderbilt family for Edison's lighting experiments, merged. Through the fall of a battle of words with Brown specifically attacking Westinghouse continued to escalate.

The magazine investigated the claim and found at most only two of the deaths could be attributed to Westinghouse installations. Although New York had a criminal procedure code that specified electrocution via an electric chair, it did not spell out the type of electricity, the amount of current, or its method of supply, since these were still relative unknowns.

During this time they sought the advice of Harold Brown as a consultant. This ended up expanding the war of currents into the development of the chair and the general debate over capital punishment in the US.

After the Medico-Legal Society formed their committee in September chairman Frederick Peterson , who had been an assistant at Brown's July public electrocution of dogs with AC at Columbia College, [79] had the results of those experiments submitted to the committee.

The claims that AC was more deadly than DC and was the best current to use was questioned with some committee members, pointing out that Brown's experiments were not scientifically carried out and were on animals smaller than a human being.

At their November meeting the committee recommended volts although the type of electricity, direct current or alternating current , was not determined.
