The London Biorhythm Company
The downside of the character of Dr. Fleiss was one of an obsessive, morose, and anti-social thinker. Sadly, these traits were to haunt him throughout much of his later life. True to form, though, and not to let the side down his natural death occurred on a day which, with his knowledge of biorhythms, he could have predicted! This is the most financially profitable use of biorhythms in the field of accident prevention. Professor Kichinosuke Tatai, M.D. founded the Japanese Biorhythm Association with the specific intention of helping major Japanese companies to save money. By using the "predictive" power of biorhythms to reduce accidents at work, and by showing huge corporations how biorhythm "compatability" could increase productivity by placing people who worked well together in the same team, or on the same shift, Professor Tatai turned "biorhythms" into an effective industrial tool. Using biorhythms in this way was so successful that important Japanese employers were able to save money on their industrial insurance costs by declaring that biorhythms were used in these spheres. Confirmation of this success is contained in any book on biorhythms by "Tatai". Many of which have been translated into English, and some are listed on the non-English language page of the chart biorhythms . The Tatai vision for the use of biorhythms in "industrial Britain" in the mid-1970 was far less successful, and is covered on the @33 page. "Hans Freuh" also picked up on the successful use of biorhythms by Japanese industry is in his million+ best-selling book on biorhythms which is listed in the main section of the chart biorhythms . Professor Tatai was also a founder member of the International Biorhythm Association, see the biography of Professor "Kardas" linked through from the chart biorhythms for further details.

The history of biorhythms revolves around such individual initiatives.
Although some people believe there are up to 7 biorhythm cycles (see London Biorhythms RESEARCH PAGE) here I am concentrating on the attributes of the 3 basic cycles which are usually associated with a Biorhythm Chart. These 3 are our Physical, Emotional and Intellectual cycles.
The PHYSICAL cycle usually coloured RED is generally thought to be the dominant cycle in males. The attributes of this cycle are strength, confidence, ambition, energy, endurance, resistance to and recovery from illness; the sex drive; and the efficiency with which the body uses up calories.
While American researchers (see Willis and Gittleson and others in the BIORHYTHM BIBLIOGRAPHY) in the 1970s studied the reaction times of airline pilots they noted that on a CAUTION (sometimes called a CRITICAL day) in this biorhythm the pilots were 6 times slower to react to the command to hit a knob when compared to the reaction times at the top (peak) of this cycle. This variation is connected with the autonomic nervous system (our automatic reactions) and helps to explain why on some days we are more accident prone.
Mothers-to-be should note all caution days in their physical and emotional biorhythms for the expected month of birth. Natural (not-induced) labour will usually begin on one of these.
To predict the sex of an unborn child you should see if the mother had a HIGH PHYSICAL together with a LOW EMOTIONAL biorhythm at the time of conception. If she did then the child is likely to be a boy. If, on the other hand, the position of these biorhythms was reversed and she had a LOW PHYSICAL and a HIGH EMOTIONAL biorhythm at the time of conception then the child is likely to be a girl.
In conceptions where both the PHYSICAL and EMOTIONAL cycles of the mother were UP or DOWN TOGETHER then no prediction as to the sex of the child can be made using this method. The basis for these predictions lies in the fact that the acidity of the womb affects which of the chromosomes (carried by the sperm) fertilises the egg.
Wilhelm Fliess noted, as others have done since, that children who are naturally left-handed are usually conceived when their mother has at least 2, but more often 3 HIGH BIORHYTHM CYCLES at the time of conception. We advertised for left-handed people to send in their details, and are able to confirm this.
Sexual desire will vary - so the obvious comment is: make the more of your high spots! 1890-1905: The physical and emotional biorhythm cycles were initially researched and analyzed by Dr. Wilhelm Fliess and Sigmund Freud in Berlin. Books and pamphlets were published. At the same time (Professor Hermann Swobada was undertaking similar research in Vienna and publishing his own papers. It has recently emerged that there is a strong possibility of Freud discussing their work in Berlin with Hermann Swobada, and that this was the reason for the irrevocable disagreement between Fliess and himself.
When the Russians occupied Vienna at the end of the Second World War in 1945 more than 40 trunks full of Swobada's original research notes were confiscated. We know know that these first went to Moscow and were then returned to Berlin and placed in the care of the Stazi, the East German secret police. With the end of the cold War their existence has been acknowledged, but declassifying and releasing the many documents in the Stazi files in taking much longer than expected - and it seems that biorhythm research is not regarded seem as a priority the release of information.
From (East) Berlin though, the study of biorhythms quickly spread thoughout the Russian satellites of the Eastern Block of the Cold War Soviet Union, and even to Russia itself where research projects were carried out. The most famous of these is known as the 1978 Moscow Taxi Drivers Study, which was widely reported by the state controlled newspaper Pravda and the news agency Reuters. Five thousand taxi drivers were assessed. The study came out in favour of biorhythms.
On the Chronological Bibliography page of this website you can find details of some of the many research papers written during these years. The period before the 1914 First World War really was a time during which human biorhythms and bi-sexuality were the domain of both the chattering classes and intellectuals throughout the German speaking world.
