Kurt Heissmeyer (26 December 1905 – 29 August 1967) was a Nazi SS physician[1] involved in medical experimentation on concentration camp inmates including children, notably seven-year old Sergio de Simone.
Although previously disproven, his hypothesis was that the injection of live tuberculosis bacilli into subjects would act as a vaccine.
Another component of his experimentation was based on pseudoscientific Nazi racial theory that race played a factor in developing tuberculosis.
The children, along with their four adult caretakers, were murdered by being hanged in the basement of Bullenhuser Damm School in Hamburg.
After the war, Heissmeyer escaped detection and returned to his home in Magdeburg in postwar East Germany and started a successful medical practice as a lung and tuberculosis specialist.
