Wilhelm Fliess was a Germanotolaryngologist who practised in Berlin. He developed highly eccentric theories of human biorhythms and a possible nasogenital connection that have not been accepted by modern scientists. He is today best remembered for his close personal friendship and theoretical collaboration with Sigmund Freud, a controversial chapter in the history of psychoanalysis.
Career
Fliess developed several idiosyncratic theories, such as 'vital periodicity', forerunner of the popular concepts of biorhythms. His work never found scientific favor, though some of his thinking – such as the idea of innate bisexuality – was incorporated into Freud's theories. Fliess believed men and women went through mathematically fixed sexual cycles of 23 and 28 days, respectively. Another of Fliess's ideas was the theory of 'nasal reflex neurosis'. This became widely known following the publication of his controversial book Neue Beitrage und Therapie der nasaelen Reflexneurose in Vienna in 1892. The theory postulated a connection between the nose and the genitals and related this to a variety of neurological and psychological symptoms; Fliess devised a surgical operation intended to sever that link. On Josef Breuer's suggestion, Fliess attended several conferences with Sigmund Freud beginning in 1887 in Vienna, and the two soon formed a strong friendship. Through their extensive correspondence and the series of personal meetings, Fliess came to play an important part in the development of psychoanalysis. Freud, who described Fliess as "the Kepler of biology", repeatedly allowed Fliess to operate on his nose and sinuses to cure his neurosis and also experimented with anaesthetization of the nasal mucosa with cocaine. Together, Fliess and Freud developed a Project for a Scientific Psychology, which was later abandoned. Fliess wrote about his biorythmic theories in Der Ablauf des Lebens. Emma Eckstein had a particularly disastrous experience when Freud referred the then 27-year-old patient to Fliess for surgery to remove the turbinate bone from her nose, ostensibly to cure her of premenstrual depression. Eckstein haemorrhaged profusely in the weeks following the procedure, almost to the point of death as infection set in. Freud consulted with another surgeon, who removed a piece of surgical gauze that Fliess had left behind. Eckstein was left permanently disfigured, with the left side of her face caved in. Despite this, she remained on very good terms with Freud for many years, becoming a psychoanalyst herself. Fliess also remained close friends with Freud. He even predicted Freud's death would be around the age of 51, through one of his complicated bio-numerological theories. Their friendship, however, did not last to see that prediction out: in 1904 their friendship disintegrated due to Fliess's belief that Freud had given details of a periodicity theory Fliess was developing to a plagiarist. Freud died at 83 years of age. Freud ordered that his correspondence with Fliess be destroyed. It is only known today because Marie Bonaparte purchased Freud's letters to Fliess and refused to permit their destruction.
Personal life
His son Robert Fliess was a psychoanalyst and a prolific writer in that field. He devised the phrase ambulatory psychosis. Jeffrey Masson claimed that Fliess sexually molested his son Robert and that this caused Fliess to undermine Freud's investigation of the seduction theory because of its implications for his life. His niece Beate Hermelin was an experimental psychologist who worked in the UK, where she made major contributions in what is now known as developmental cognitive neuroscience.
Legacy
Medical science has given a highly negative verdict to Fliess' theories. The nasogenital theory was briefly quite popular in late 19th century medical circles, but within a decade disappeared from the medical literature. Most scientists who have studied the question believe that the biorhythms theory has no more predictive power than chance and consider the concept an example of pseudoscience. According to Frank Sulloway, most of Freud's sympathetic biographers have attributed Freud's adherence to Fliess' pseudoscience to their strong personal friendship. Martin Gardner suggested that Freud's willingness to entertain Fliess' "crackpottery" casts doubt on psychoanalysis itself and has strongly condemned what he viewed as orthodox Freudians' attempts to hush up an embarrassment in the history of the movement. Fliess appears as a character in Joseph Skibell's 2010 novel, A Curable Romantic. The story of the relationship between Freud and Fliess is told by Martin Gardner in his July 1966Mathematical Games column in Scientific American.
