The 6 Deadliest Scientific Experiments in Human History

KOMPAS.com – Scientific experimentation has developed throughout human history, not only for welfare, but also for the performance of power.

Some of the deadliest scientific experiments have been carried out by previous generations, often without knowing the limits of human morality, Unit 731 among them.

Unit 731 was the name of the Imperial Japanese Army’s secret biological and chemical warfare division during World War II. Many scientific experiments were carried out under Unit 731, from the creation of plagues, to surgery and amputation without anesthesia, to weapons testing, to rape to transmit disease.

Apart from Unit 731, there are other scientific experiments no less deadly. Following Kompas.com summarizes a list of 6 of the deadliest scientific experiments in history that launch from several sources:

Project MKUltra is a secret CIA project for mind control. The program began in the 1950s and lasted until 1966.

Under MKUltra, people who are research subjects are often given drugs, especially hallucinogens, such as LSD.

The people tested were then subjected to sleep and sensory disturbances, hypnosis, sexual abuse, and other types of psychological torture, while some of the tests proved lethal.

The main objective of the project was to combine chemical weapons research and efforts to create mind control drugs to fight the Soviets.

The Tuskegee Syphilis scientific experiment was a government-funded experiment from 1932-1972. In this scientific experiment doctors refused to treat 399 African-American syphilis patients in rural Alabama, even when penicillin was discovered, which was effective against syphilis in 1947.

The syphilis patients were also not told they had syphilis, the doctors simply blamed their “bad blood” and gave a placebo.

The purpose of the Tuskegee syphilis scientific experiment conducted by the U.S. Public Health Service was to study the natural progression of syphilis if left untreated.

There were 28 people in the study who were infected with syphilis died immediately, while 100 died from syphilis-related complications.

This gruesome experiment on sexually transmitted diseases in Guatemala is another example of the US government causing losses in its pursuit of “science”.

From 1945 to 1956, about 1500 Guatemalans were intentionally infected with sexually transmitted diseases, including syphilis and gonorrhea.

Research subjects include orphans, prisoners, prostitutes, and conscripted workers.

Researchers use prostitutes to make them suffer from sexually transmitted diseases, by injection and other immoral methods.

Experimental subjects are currently suing John Hopkins University for $1 billion for their role in the study.

4. Aversion project scientific experiment

A program of medical torture was instituted in South Africa between 1971 and 1989 to “cure” homosexuality in military service.

The policy, implemented under apartheid, includes forced “aversion therapy” treatments, such as electric shock therapy and chemical castration. The army also authorized as many as 900 sex-change operations.

The medical community at the time widely believed that homosexuality was a curable mental illness.

Dr Aubrey Levin, who was in charge of the program as South Africa’s chief military psychiatrist, was eventually accused of human rights abuses by international organizations and received a prison sentence.

The Nazis conducted scientific experiments on thousands of prisoners in concentration camps, regardless of human life.

Some of the Nazis’ deadliest scientific experiments were carried out on purpose, such as inducing hypothermia, infecting people with malaria, using mustard gas on people, forced sterilization, giving prisoners various poisons, infecting wounds with bacteria and filling them with wood shavings and ground glass.

Nazi doctor Josef Mengele was an “evil scientist” known for the deadliest experiments he carried out in Nazi concentration camps, with a particular focus on twins, mostly Jewish or Roma (“Gypsies”).

Doctor Mengele was responsible for atrocities, such as removing humans without anesthesia, injections containing deadly bacteria, mutilation, and so on. So cruel, Doctor Mengele was known as the “Angel of Death”.

Mengele collected the eyes of the slain victims for heterochromic research and sought to prove through experiments the alleged resistance of Jews and Romans to a number of diseases.

6. Scientific Experiment Unit 731

Unit 731 is a secret unit of the Japanese Army that conducted the deadliest scientific experiments on humans during World War II.

Led by General Shiro Ishii, Unit 731 conducted scientific experiments on approximately 250,000 men, women, and children. Most of the victims were Chinese, along with some prisoners of war from Russia and the Allies.

The deadliest scientific experimental procedures Unit 731 performed, including surgery without anesthesia, amputation of unnecessary limbs, and removal of organs, such as parts of the brain, liver, lungs and others.

Victims of this deadliest scientific experiment were also subjected to biological warfare, frostbite testing, forced pregnancy, and even weapons testing with grenades or flamethrowers.
