Franz Halberg (born July 5, 1919 in Bistritz , Romania ; † June 9, 2013 ) is the founder of chronobiology and the creator of the term circadian rhythm .
life and work
Halberg began his experiments on rhythms within living organisms in the 1940s. At the University of Minnesota he founded Chronobiology Laboratories, of which he was director until his death. He worked in almost all areas of research into the rhythms of life, and in doing so he was able to demonstrate that there are much longer-term periodicities than the circadian ones, which can even extend over many years.
He published more than 3000 papers alone or with his colleagues.
His more recent work on interrelationships in the field of solar-terrestrial physics has also become known , including using long-term aurora data published by Wilfried Schröder on the Maunder Minimum . Halberg was able to prove several periods from the field of solar-terrestrial relationships. He was also able to show in a large number of papers that there are many diseases that are related to certain rhythms of life or their disorders.
Franz Halberg was since 2001 member of the Leibniz Society of Sciences in Berlin eV
Halberg died on June 9, 2013 at the age of 93.
