Luis Alexander Zlotin, the first of three children, was born on December 1, 1910 th, in Winnipeg, Manitoba, Canada (Winnipeg, Manitoba, Canada), where his parents had fled from Russia (Russia) during the pogrom. His younger brother, Sam noted that Louis had a deep concentration that allowed to do research for hours.

At the age of 16 years Zlotin entered the University of Manitoba to earn a degree. Student Luis received a gold medal for his achievements in physics and chemistry. With a degree in geology at the hands of, a graduate of the University in 1933, went on to additional training at the Royal to lledzh in London (King `s College London), which took over the knowledge Arthur John Allmanda (Arthur John Allmand), a specialist in the field of applied electrochemistry and photochemistry.

In college, Luis, try their hand at the sport, he won the championship among amateur boxing boxer bantamweight. In 1936, he defended his PhD thesis on the subject of physical chemistry. Next Zlotin worked six months as a special test to Dublin rail, where the tested nickel-zinc batteries `Drumm`, used on line Dublin-Bray.

In 1937, after failing to get into the National Research Council of Canada, Zlotin settled the University of Chicago (University of Chicago). As scientific employee of the University, Louis first encountered in practice, nuclear chemistry, when he helped to build the first in the US Midwest cyclotron.

Position brought pennies, which is why Zlotin two years could not do without the financial assistance from the father. In 1939-1940. Louis Evans and Earl (Earl Evans), head of the Department of Biochemistry, University of Chicago, received with the help of a cyclotron radiocarbon (carbon-14 and carbon-11). They also demonstrated that plant cells have the ability to use carbon dioxide for the biosynthesis of carbohydrates.

Zlotin could attend the launch of `Chicago woodpile - 1`, the first artificial nuclear reactor, 2 December 1942. However, in the report about the launch of a chemist it does not say anything. During this period, Louis wrote several works on radiobiology. His experience has attracted attention from the US government, which invited Zlotina participate in the Manhattan Project.

The project Luis worked on plutonium production under the direction of the future Nobel laureate Eugene Wigner (Eugene Wigner). In December 1944 Zlotin moved to Los Alamos National Laboratory in New Mexico (New Mexico), where he worked with Robert Bechera team (Robert Bacher).

The laboratory conducted Zlotin dangerous experiments - first figured out the critical mass of uranium, together with Robert Frisch, Otto (Otto Robert Frisch), and then studied the division of plutonium nuclei. Scientists call these `zaigryvaniya` with the possibility of a nuclear chain reaction `tickling the tail drakona`, making reference to the remark physicist Richard Feynman (Richard Feynman), once compared the similar experiments with` tail tickling sleeping drakona`.

July 16, 1945 th Luis gathered the filling of the first exploded an atomic device, code-name `Triniti`. Thanks to its expertise in the assembly of nuclear weapons, Zlotin became known as the `chief armorer of the United Shtatov`.

A little later, on August 21, 1945, a close colleague Louis assistant Harry K. Daglyan (Harry K. Daghlian), performing a dangerous experiment, accidentally dropped the bar of tungsten carbide to 6.2 kg plutonium with gallium alloy used in nuclear warheads. Daglyan received a large dose of neutron radiation, which, according to the assumptions in itself was not fatal. However, turning the experiment, 24-year-old Harry suffered from additional gamma radiation and beta burns. He died 25 days later.

May 21, 1946 th Zlotin, along with seven colleagues, conducted an experiment to initiate the first steps of a chain reaction - by bringing together the two beryllium-covered plutonium hemispheres. We used all the same core 6.2 kg of plutonium with gallium alloy, subsequently called `demon yadrom`. Zlotin used a screwdriver in his right hand to adjust the gap between the hemispheres. When the screwdriver slipped, his left hand dropped the chemist 9-inch upper hemisphere - and the body Zlotina received a lethal dose of radiation.

When connecting polusfernablyudateli saw the blue glow of ionized air and felt the heat wave. Zlotin experienced a sour taste in the mouth and an intense burning sensation in his left hand. The main victims started vomiting as soon as he left the room. Louis was taken to hospital, where the mass of volunteers agreed to give their blood for a possible transfusion. However, it soon became clear that death is inevitable.

Lieutenant General US Army Leslie R. Groves (Leslie R. Groves) Zlotina told his parents about the sad state of their son. Over the next nine days, Louis was suffering from severe diarrhea, decrease in urine output, erythema, massive blisters on the hands and forearms, intestinal obstruction and gangrene. In the end, there was a destruction of all body functions.

Luis Zlotin died surrounded by parents 30 May 1946.

His colleague Alvin K. Graves (Alvin Graves), who was standing closest to Zlotina at the time of the incident, has earned acute radiation sickness and spent several weeks in hospital. Graves was tormented by chronic neurological diseases and vision problems. He lived in `54; cause of death was a heart attack.

Another victim, Marion Edward Chishlitski, died 19 years after Zlotina from acute myeloid leukemia at the age of 42 years. There is information about another colleague Zlotina, participated in the fatal experiment. It`s about Dwight Yange, who died at the age of 83 years - from aplastic anemia and bacterial infection of the heart.
