Swiss neurologist. He became ‘the doctor of princes and the prince of doctors’ after writing two books: Advice to People on their Health, which has been translated into 17 languages, and Onanism: A Dissertation on the Diseases Caused by Masturbation, which has been republished 63 (!) times. Even Voltaire and Kant accepted Tissot’s arguments against onanism (which we put down to his Calvinistic views), and they permeated Western medicine for two whole centuries. We won’t list all of Tissot’s titles and awards; suffice it to say he treated the King of Poland, was welcomed by the Pope and received a letter of thanks from Napoleon Bonaparte.
