The Russians, arguably the ones who perfected the practice, have put both Vladimir Lenin and Joseph Stalin on long-term display. Lenin's body has been embalmed in a large tomb near the Kremlin since shortly after his death in 1924, preserved by a steady 61 degree temperature and a strict regimen of mild bleachings and soaks in glycerol and potassium acetate.
According to Time, Stalin's embalmed body also laid near Lenin's for about 10 years, but was hastily reburied under cover of darkness when the government tried to squash his cult of personality in the early '60s.
The Russians seem to have inspired the North Koreans to similar displays. In 1994, a Russian team helped preserve the body of Kim Il-sung, North Korea's founding president, the New York Times reports.
When Kim Jong Il died in late 2011, Russian scientists again went to Pyongyang to assist in the embalming; the late leader lies in a glass sarcophagus with filtered lights to keep his face looking rosy.
But Kim Jong Il and his father were by no means the first Asian leaders to get the Chavez treatment. The Vietnamese revolutionary Ho Chi Minh, who died in 1969, is displayed in a mausoleum in Hanoi modeled after Lenin's. Since "Uncle Ho" died in the midst of the Vietnam War, his embalmers had to work in a cave in the North Vietnamese jungle, the New York Times reports.
One of the scientists who worked on him told the Times: “Not every expert is allowed to restore such treasured historical objects, like a Raphael or a Rembrandt. Those who do it, we tremble. I feel a great responsibility in my hands.” This video shows the changing of the guard outside Ho Chi Minh's tomb.
Socialist leader Mao Zedong has lain in state in a mausoleum on Beijing's Tiananmen Square since May 1977. According to Time, Soviet-Chinese tensions forced Mao's embalmers to ask the Vietnamese, not the Russians, for advice -- a plan that misfired slightly when the Vietnamese could not explain how to build an air-tight coffin.
The exiled Filipino dictator Ferdinand Marcos, who died in 1989, has lain embalmed in a public mausoleum in the northwest Philippines since the government allowed his body back into the country in 1993. His widow, Imelda Marcos, has battled the government for permission to bury him in the country's presidential cemetery, the New York Times reports. She posted for photos kissing the crypt in 2010.
Chavez will be only the second Latin American leader to be preserved for all eternity. Embalmers emptied water from the cells of Eva Peron, the wife of Argentinian president Juan Peron, and replaced them with wax -- an unusual technique that basically "turned her into a candle," Egyptologist Bob Brier told the Post's Monica Hesse in 2012. She's now also missing a finger -- when the junta overthrew Peron's husband and took over their house, they cut one off to see if the body was fake.
Chavez's body will, presumably, get better protection than that. AFP reports that Marcos's embalmer has already offered up his services and is urging the Venezuelans to start the process before it gets "more difficult."
"I will process anyone, anywhere," he said, helpfully.
