From Wikipedia: The Royal Canadian Electrical and Mechanical Engineers came into being officially on 15 May 1944, with the fusion of various elements from the Royal Canadian Engineers, Royal Canadian Army Service Corps and Royal Canadian Ordnance Corps, following the model of the Royal Electrical and Mechanical Engineers (REME). With the increase of mechanized equipment during World War II, the need to have one corps dedicated to service and maintenance thereof was becoming increasingly apparent. Trucks had become the de facto means of transportation and logistic support, armoured vehicles had replaced cavalry, weapons were becoming more complicated, as well as the advent of radios and radar, it was apparent that the previous model of having a different corps for each job was inadequate for a modern, mechanized army. The majority of RCEME (pronounced /?ri?mi?/ REE-mee, even though there is a "C" in it, just as "REME" is pronounced) technicians were, and still are, vehicle mechanics, but the original RCEME structure incorporated 25 different trades and sub-trades, employing specialists for each particular job in order to train and deploy them in time to meet the war's demand. While it was somewhat bulky, it was nonetheless a centralized structure for maintaining the Army's everyday equipment which was more efficient than the previous system of having each corps perform its own equipment maintenance, and also allowed for a greater degree of specialization within trades.

Dr. Nikola Tesla was one of the most brilliant inventors of history and was of an unusual intellectual vision. He is affectionately refered to as the "Father of Free Energy". Tesla was a world-renowned Serbian-American inventor, physicist, mechanical engineer and electrical engineer, born in Smiljan, Austrian Empire (present day Croatia). Tesla is regarded as one of the most important inventors in history. He is also well known for his contributions to the discipline of electricity and magnetism in the late 19th and early 20th century. His patents and theoretical work form the basis of modern alternating current electric power (AC) systems, including the polyphase power distribution systems and the AC motor, with which he helped usher in the Second Industrial Revolution. In the United States, Tesla's fame rivaled that of any other inventor or scientist in history or popular culture. After his demonstration of wireless communication in 1893 and after being the victor in the "War of Currents", he was widely respected as America's greatest electrical engineer. Much of his early work pioneered modern electrical engineering and many of his discoveries were of groundbreaking importance. Tesla's legacy can be seen across modern civilization wherever electricity is used. Aside from his work on electromagnetism and engineering, Tesla is said to have contributed in varying degrees to the fields of robotics, ballistics, computer science, nuclear physics, and theoretical physics.
