Turing was famously chemically-castrated after admitting to homosexual acts in the 1950s. He is one of a long line of scientists who have been persecuted for their beliefs or practices

[partner id="wireduk"] After admitting to "homosexual acts" in early 1952, Alan Turing was prosecuted and had to make the choice between a custodial sentence or chemical castration through hormone injections. Injections of oestrogen were intended to deal with "abnormal and uncontrollable" sexual urges, according to literature at the time.

He chose this option so that he could stay out of jail and continue his research, although his security clearance was revoked, meaning he could not continue with his cryptographic work. Turing experienced some disturbing side effects, including impotence, from the hormone treatment. Other known side effects include breast swelling, mood changes and an overall "feminization". Turing completed his year of treatment without major incident. His medication was discontinued in April 1953 and the University of Manchester created a five-year readership position just for him, so it came as a shock when he committed suicide on 7 June, 1954.

Turing isn't the only scientist to have been persecuted for his personal or professional beliefs or lifestyle. Here's a a list of other prominent scientific luminaries who have been punished throughout history.

__Rhazes (865-925)

__ Muhammad ibn Zakariyā Rāzī or Rhazes was a medical pioneer from Baghdad who lived between 860 and 932 AD. He was responsible for introducing western teachings, rational thought and the works of Hippocrates and Galen to the Arabic world. One of his books, Continens Liber, was a compendium of everything known about medicine. The book made him famous, but offended a Muslim priest who ordered the doctor to be beaten over the head with his own manuscript, which caused him to go blind, preventing him from future practice.

__Michael Servetus (1511-1553)

__ Servetus was a Spanish physician credited with discovering pulmonary circulation. He wrote a book, which outlined his discovery along with his ideas about reforming Christianity – it was deemed to be heretical. He escaped from Spain and the Catholic Inquisition but came up against the Protestant Inquisition in Switzerland, who held him in equal disregard. Under orders from John Calvin, Servetus was arrested, tortured and burned at the stake on the shores of Lake Geneva - copies of his book were accompanied for good measure.

Galileo (1564-1642)

The Italian astronomer and physicist Galileo Galilei was trialled and convicted in 1633 for publishing his evidence that supported the Copernican theory that the Earth revolves around the Sun. His research was instantly criticized by the Catholic Church for going against the established scripture that places Earth and not the Sun at the center of the universe. Galileo was found "vehemently suspect of heresy" for his heliocentric views and was required to "abjure, curse and detest" his opinions. He was sentenced to house arrest, where he remained for the rest of his life and his offending texts were banned.

__Henry Oldenburg (1619-1677)

__ Oldenburg founded the Royal Society in London in 1662. He sought high quality scientific papers to publish. In order to do this he had to correspond with many foreigners across Europe, including the Netherlands and Italy. The sheer volume of his correspondence caught the attention of authorities, who arrested him as a spy. He was held in the Tower of London for several months.

__Gerhard Domagk (1895-1964)

__ Domagk was a German pathologist and bacteriologist who is credited with the discovery of the first commercially-available antibiotic, sulfonamide, for which he was awarded the Nobel Prize for Medicine in 1939. Because a Nazi-critical Carl von Ossietzky had won the Nobel Peace Prize in 1935, Domagk was forced by the Nazi regime to refuse the prize. He was arrested by the Gestapo for a week. After the war, in 1947, he was finally able to receive his Nobel Prize, but not the associated cash prize because too much time had elapsed.

Albert Einstein (1879-1955)

Born in Ulm in Germany, Einstein was a non-practicing Jew. His work on the General Theory of Relativity and his pacifist politics roused violent animosity from right-wing members of German society. When Hitler came to power in January 1933, Einstein was in California and was almost immediately deprived of his posts in Berlin and his membership of the Prussian Academy of Sciences. His property was seized and his books were burned in public. Einstein never returned to Germany, and signed a letter to President Roosevelt alerting him to the fact that Germany might be developing an atomic weapon. He recommended that the US begin similar research.
