Empires of Light: Edison, Tesla, Westinghouse, and the Race to Electrify the World [Hardcover]

PAY NO ATTENTION TO THE POOR REVIEW FROM johnjones2! I will base my review of this book based on his ridiculous 2 star review. I have been an Electrical Engineer since the mid-1980s. I enjoyed this book tremendously! This is a book that deals with the history of the THREE PRIMARY men who began the war of AC vs. DC electric currents. They are Edison, Westinghouse, and Tesla.

Apparently reviewer johnjones2 does not know his history. Charles Proteus Steinmetz never worked for Westinghouse; he worked for GE (that's common knowledge). He didn't join the GE staff until 1893, which was the year of the Colombian Exposition in Chicago. The war of electric currents was well under way before Steinmetz ever joined the GE staff. As you'll learn in this book (and others), the Colombian Exposition was a major battle ground for the war of electric currents. Steinmetz was an outstanding electrical engineer who later worked (for GE) to help optimize the AC motor by solving hysteresis issues. It was TESLA'S (who began working for Westinghouse in 1888 after a short stint with Edison), NOT Steinmetz's, ALL-IMPORTANT PATENTS that were needed to get the AC business going. That's the way business works! This book is about how the AC / DC war began and how AC proved to be the better technology (that's why our homes are now wired for AC). It's not about how AC systems were later perfected.

Am I bothered that the author didn't mention Steinmetz - heck no. There are many other engineers who have worked on AC systems to make them better and more efficient, did I expect all of them to be mentioned in this book as well - again, heck no! For reviewer johnjones2 to say that the author had ulterior motives for leaving out Steinmetz is completely hilarious!

In 1889, Steinmetz had to flee Germany because of his SOCIALIST activities (ulterior motive?), he then came to the United States. Rudolf Eickemeyer, who had begun building electrical apparatus in his factory in Yonkers, N.Y., gave Steinmetz his start in electrical engineering research. When GE bought out Eickemeyer in late 1892, Steinmetz remained on the staff and began working under the new owners.

Now lets move on to reviewer johnjones2's technical issues. Really, there are none. The author does a good job setting the groundwork for how scientists began studying and discovering the basics of electricity and how that knowledge was developed so that man could harness the power
of electricity and use it in the way that we use it today. The so-called technical errors that are pointed out by johnjones2 are based on very trivial issues. I found his complaints about the authors "scientific drawings" completely off base and without merit. The author provides 11 diagrams and basic electrical schematics that help give the average reader an idea of the concepts involved. They are very basic in nature and are diagrams that are still used today to help explain the fundamentals of electricity. These are not "misleading" in any way. When reviewer johnjones2 complains about the author rating electrical generators in horsepower and says "something that certainly hasn't been done for a century", well, I think he missed the point. This book is about the history of AC/DC electricity and how it was developed a CENTURY ago.

Lastly, as far as johnjones2's comment "she (the author) specifies early systems by the number of bulbs they could light-- as if all light bulbs had the same power consumption (but perhaps they did in the earliest days)", what an ambiguous statement. This one's not even worth the time.

This is an excellent book written by a historian, not an Electrical Engineer (can you imagine how boring this book would have been if an Electrical Engineer had written it). This book is a good read for anyone and especially those who love reading about the Gilded Age era of American history.

This is a fairly good book on three pioneers of the electrical revolution: Edison, Tesla, and Westinghouse. Only the last was a true industrialist, while the first two were inventors who more or less failed to capture the full value of what they created. The field of battle was was between direct current (DC) and alternating current (AC). Jonnes also attempts to evoke the era - one of huge transition, both technological and social/organizational - in which they lived.

The best things about this book are in overview and context. I learned about the business environment and practices during the Gilded era, which was indeed extremely interesting and useful for my current project. This is well researched and clearly written. Moreover, what each of these individuals faced - their frustrations, ambitions, motivations, and methods - are also examined in some detail. While I know a lot about Edison from previous research, this was a gold mine of info on his principal competitors, Westinghouse and Tesla, whose technology (AC) won the battle to become the standard of wire-furnsihed electric power. Edison was an incredible inventor, but his obstinancy for sticking to what he created led him to bypass AC for the less workable DC (this is a pattern that led him to many strategic mistakes thru his career). Tesla was an eccentric visionary and loner, who made great discoveries early on only to get mired into megalomanaical schemes during the last decades of his life. Westinghouse was a true "broker of innovation" - finding and using talent with great efficiacy - and in many ways a brilliant pioneer of corporate and industrial organization; he was also a decent man with populist ideals in a time of ruthless exploitation and manipulation.

However, this book failed for me on many counts. First, it did not go into enough technological detail for me - I still don't understand the difference between AC and DC from a scientific point of view. Second, I did not get much of a feeling for a story (billed on the cover as a titanic struggle) that was unfolding: instead, the book jumped around and got bogged down in certian details, such as the grizzly chapter on Edison's promotion of an AC-current electric chair (to scare the public) or the maneuvering that preceeded the COlumbian Exposition.

Third, and this is a very personal perception, I did not like the way that Jonnes writes. While her book certainly was not as dry or lifeless as so many academic studies tend to be, I felt she was straining to write as eloquently as McCullough or Schama, which I believe is beyond her talent. This criticism may come from writing 101, but she uses too many adjectives. Waves of panic are "ungulating," electicity is "ethereal," etc., each time failing to find "le mot juste." I really don't mean to be a snob about this - she is a better historian than I ever could be - but her writing style irritated me several times on every page.

Recommended with these caveats in mind.

Jonnes gives us a look at the story of electrification from Edison's discovery of the incandescent light to completion of the Niagara Falls hydroelectric generating station (using Westinghouse equipment based on Tesla's AC patents). She begins with an overview of what was known about electricity-the relationship between electricity and magnetism, discovered by Michael Faraday, and the development of electromagnets by Joseph Henry. Development of practical generators in the 1870s, was soon followed by the first arc lights, but they were cumbersome and too bright for home use. Edison took up the challenge to develop an electric light suitable for home use in 1878, completed in 1879, and installed in New York City in 1882.

Edison firmly believed in his DC power system, but it was poorly suited to transmitting power long distances. Once AC transformers were invented, in 1885, George Westinghouse realized that AC was the more practical system. He licensed Tesla's patents for AC generator and motor and began installing systems. A major battle ensued with Edison promoting DC and charging that AC was unsafe. That resulted in the adoption of the AC powered electric chair as a means of execution. Edison General Electric and Westinghouse found themselves in direct competition many times.

Edison was a darling of the media. His side of the story has been told many times. Westinghouse was personable, but far less open to the press. No biographies have appeared since 1926. Tesla was a frequent publisher, gave numerous demonstrations especially at technical meetings. His eccentric nature leads to some treatments as a man of mystery.

The detailed treatment of the Niagara Power project is much appreciated. This was the first major hydroelectric project in the US. It was financed by a Wall Street syndicate headed by JP Morgan. We see the details of how the bankers brought in experts to get the best available advice on the project. Finally Westinghouse won the competition because he had licensed the Tesla AC patents. There was no nearby customer for the power from Niagara. Buffalo, 26 miles away was the logical one. But the project also spawned numerous industries that took advantage of low cost electric power. This is the founding of well known companies. Among them Alcoa (first production of low cost aluminum), Carborundum (abrasives made by electric furnace), Union Carbide (acetylene made by electric furnace), and Hooker Chemical (chlorine, bleach, alkalis, sodium hydroxide, sodium all made by electrolysis of salt water). Niagara began supplying power to Alcoa on Aug 26, 1895.

The book also gives us a profile of three inventors: Edison, Westinghouse, and Tesla. We are shown how financiers dealt with them. In Feb, 1892, JP Morgan and associates merged Edison General Electric with another holding, Thompson Houston, renamed the combine General Electric Co., and put CEO Charles Coffin in charge without even consulting Edison. George Westinghouse lost control of his company after it sank into bankruptcy in the Panic of 1907. He was soon forced out of the company. A proxy fight to regain control in 1911 failed. Tesla licensed his key AC patents to Westinghouse and initially received generous royalties. But he agreed to give up those royalties as part of a Westinghouse rescue plan in the Panic of 1891. His other patents were tied up in a deal with JP Morgan to fund radio development. After Marconi beat him to market, he was unable even to defend his own patents. He died penniless.

This is a great read for those interested in technology and how it all came together. We are left hungering for a second volume to cover the rest of the electrification story. We hear nothing of Samuel Insull, very little of the development of electric street cars, electric railroads, interurbans, the electric automobile, TVA, rural electrification, or the expansion of electrical systems throughout the country. Excellent bibliography. Many references. Index.
