Johann Sigismund Elsholtz

Johann Sigismund Elsholtz (August 26, 1623 – February 28, 1688), (some sources mention his day of birth as August 28, and his death on February 19) was a German naturalist who was a native of Frankfurt an der Oder. 

Biography
Johann Sigismund Elsholtz studied at the Universities of Wittenberg, Königsberg and Padua, where he received his doctorate in 1653.  He was appointed court botanist, alchemist and physician to Elector Friedrich Wilhelm of Brandenburg (1620-1688), and in 1657 was put in charge of Friedrich Wilhelm's botanical gardens at Berlin, Potsdam and Oranienburg. 

In 1654, he published Anthropometria, an early study of anthropometry.  This book was written for the benefit of artists and astrologers, as well as for students of medicine and physiognomy.  It examines the perceived relationship between proportions of the human body and the incidence of disease. 

Elsholtz was a pioneer in the fields of hygiene and nutrition, and in his writings on holistic health, he stressed the importance of clean air and water, healthy food and drink, and also personal cleanliness. 

In his 1665 work Clysmatica nova, he investigated the possibilities of intravenous injection.  He performed early research of blood transfusions and "infusion therapy", and speculated that a husband with a "melancholic nature" could be re-vitalized by the blood of his "vibrant wife", thus leading to a harmonious marriage. 

The botanical genus Elsholtzia is named in his honor.  This plant genus includes the species Elsholtzia ciliata.
