Childhood and Family

. His father, François Marie Etienne Forel (1765-1865) was a well-respected historian and a jurist and was a strong influence in Forel's life. From a young age, François-Alphonse Forel became involved in some of archaeological studies of his father's colleagues. Several of Forel's family members were also respected scholars and scientists.


Education

Forel began his education at the Collège de Morges. Eventually, he left Morges for secondary school in Geneva at the Gymnase de Genève. There, he studied the natural sciences and medicine. Then he attended university at Académie de Genève where he obtained a Bachelor of Letters and a Bachelor of Physical and Natural Sciences. When he turned 18, he left his home country to attend the Académie de Montpellier in Montpellier, France. He studied at the university for two years and spent a portion of time after that, studying medicine on his own in Paris, France. Later, he moved to Germany and studied at the University of Würzburg. In the year 1865 when Forel was 24 year old, he obtained a doctorate degree in Medicine and Obstetrics.


Work and Professional Life

Shortly after obtaining his doctoral decree, Forel returned to Lake Geneva in Switzerland. There, he began his own study of the lake which encompassed zootomy, physics, chemistry, biology, natural history, and even economics. In 1869, he became a science professor at the University of Lausanne (then known as the Academy of Lausanne) which was located near his home at Lake Geneva. He taught histology, anatomy, and physiology. But his real love was the lake;Vincent, Warwick F., and Carinne Bertola. "Lake physics to ecosystem services: Forel and the origins of limnology."

("limnography" could have been confused with the limnograph, which measures water level in lakes). In his chief work, '' Le Léman'' was published in three volumes between 1892 and 1904. The volumes covered a range of topics including the definition of limnology, as well as the geographic settings, geology, climatology, hydrology and bathymetry of lake systems. The Monograph then went on to describe lacustrine hydraulics, seiches, waves and currents, temperature stratification, optics, acoustics and chemistry. This was cemented by his publication of a handbook on the topic. He discovered the phenomenon of

End of Life & Legacy

By the time of his death in 1912, he had amassed a total of 288 academic publications. So wide was his knowledge that he was referred to as "the Faraday of Lakes" in his obituary in Nature Magazine. He was well regarded by the Scottish scientific community, visiting at least once, and also being elected as an honorary fellow of the Royal Society of Edinburgh. The Institute F.-A. Forel of the
