Channel 4's new documentary, Hitler's DNA: Blueprint of a Dictator, has analysed the genetic material of Adolf Hitler, uncovering evidence of a rare disorder. The programme, which aired over two parts, aimed to settle long-standing rumours about the Nazi leader's health and ancestry.
Researchers obtained a blood-stained fabric from the sofa where Hitler died, found in a museum in Gettysburg, Pennsylvania. They matched the Y-chromosome to a sample from a male relative of Hitler, collected a decade earlier. Professor Turi King, who previously verified the remains of Richard III, led the genetic analysis alongside historian Dr Alex Kay.
The study found a deletion in the PROK2 gene, indicating Hitler had Kallmann syndrome, a condition that prevents full puberty. This aligns with prison medical records from 1923, which noted an undescended right testicle. The syndrome can also cause a micropenis and low testosterone levels.
The documentary also debunked claims of Jewish ancestry, which had persisted due to Hitler's father being illegitimate. The genetic evidence showed no Jewish lineage. The programme suggested that Hitler's medical conditions may have influenced his psychology, though some critics questioned the ethical justification for the research.
