Good question.
Communists in attempt to deify him posthumously, actually used mummification methods.
Russian scientists have developed experimental embalming methods to maintain the look, feel and flexibility of the Soviet Union's founder’s body, which is 145 years old today.
The job of maintaining Lenin's corpse belongs to an institute known in post-Soviet times as the Center for Scientific Research and Teaching Methods in Biochemical Technologies in Moscow. A core group of five to six anatomists, biochemists and surgeons, known as the "Mausoleum group," have primary responsibility for maintaining Lenin's remains. (They also help maintain the preserved bodies of three other national leaders: the Vietnamese leader Ho Chi Minh and the North Korean father–son duo of Kim Il-sung and Kim Jong-il, respectively.) The Russian methods focus on preserving the body's physical form—its look, shape, weight, color, limb flexibility and suppleness—but not necessarily its original biological matter.
The leaders eventually agreed to try an experimental embalming technique developed by anatomist Vladimir Vorobiev and biochemist Boris Zbarsky. The first embalming experiment lasted from late March to late July in 1924. Such an effort was complicated by the fact that the physician who carried out Lenin's autopsy had already cut the body's major arteries and other blood vessels. An intact circulatory system could have helped deliver embalming fluids throughout the body.
Lenin Lab researchers eventually developed microinjection techniques that used single needles to deliver embalming fluids to certain bodily parts, preferentially places where cuts or scars from past treatments already existed, Yurchak says. They also created a double-layered rubber suit to keep a thin layer of embalming fluid covering Lenin's body during public display; a regular suit of clothes fits over the rubber suit. The body gets reembalmed once every other year; a process that involves submerging the body in separate solutions of glycerol solution baths, formaldehyde, potassium acetate, alcohol, hydrogen peroxide, acetic acid solution and acetic sodium. Each session takes about one and a half months.
So as you can see, BADecker. In a way, Lenin is still alive...
Oh come on. Even Lenin doesn't think so.
