Albert Einstein
Generally recognized as one of the greatest physicists of all time, he urged the United States to use atomic energy in bombs. His special theory of relativity included gravitation as a determiner of the curvature of a space-time continuum, the basis of all theoretical and practical time travel. The most important of his inventions for the military was his unified field theory which explains gravitation and electromagnetism with one set of laws, thereby making weapons like the Chronosphere not only possible but practical. On his deathbed, reflecting on his lifes work, he warned The unleashed power of the atom has changed everything save our modes of thinking and we thus drift toward unparalleled catastrophe.
Nikola Tesla
A prolific inventor and a pioneer in high-tension electricity, he made many discoveries and inventions of great value to the development of radio transmission, radar and to the field of electricity, including an arc-lighting system, the Tesla induction motor, the Tesla coil, and various generators and transformers. In 1938 he and his colleagues developed and conducted a series of experiments in stealth technology, radar jamming, electronic shrouding and mind control which were conducted and carried out in secret.
Joseph Stalin
In 1903, Stalin (an assumed name meaning Man of Steel) joins the Communist Party. In 1924, Stalin executes other members of the ruling committee, gaining control of entire party. In 1928 he orders the liquidation of 4.5 million kulaks (rich landowners) who resist collectivization of agriculture. In 1932, he starts a famine in the Ukraine and in the Caucasus that will kill millions. He does this to starve kulaks who still resist collectivization, seizing their grain and livestock, keeping out relief supplies. In 1935, Stalin strangles his eldest son Jakov, and kills two of his daughters. In 1936, he begins a Great Purge (Yezhovschina) which will take an estimated 8 to 10 million lives in the next 2 years as he liquidates his political enemies. Authorities believe he is responsible for killing at least 60 million Russians who stood in the way of his quest for power. One of his most stunning quotes came after he had personally signed death warrants for 62,000 military officers who were resisting him. "To choose ones victims, to prepare one's plan minutely, to slack an implacable vengeance, and then to go to bed - there is nothing sweeter in the world."
