Emil von Behring (ˈeːmiːl fɔn ˈbeːʁɪŋ; Emil Adolf von Behring), born Emil Adolf Behring (15 March 1854 – 31 March 1917), was a German physiologist who received the 1901 Nobel Prize in Physiology or Medicine, the first one awarded in that field, for his discovery of a diphtheria antitoxin. He was widely known as a "saviour of children," as diphtheria used to be a major cause of child death. His work with the disease, as well as tetanus, has come to bring him most of his fame and acknowledgment. He was honored with Prussian nobility in 1901, henceforth being known by the surname "von Behring." Behring was born in Hansdorf, Kreis Rosenberg, Province of Prussia (now Ławice, Iława County, Poland). His father was a schoolmaster; the family had 13 children. Between 1874 and 1878, he studied medicine at the Kaiser-Wilhelm-Akademie in Berlin, an academy for military doctors, since his family could not afford the university. As a military doctor, he studied the action of iodoform. Due to his work on Neurotomia opticociliaris (or optociliary neurotomy), Behring became a doctor from the institute and later was able to pass his exam for licensed work in his area of Marburg. In 1878, his service required him to be sent to Poland where he focused on septic diseases. His potential was becoming well known to many. This led to his commanded return to Prussia to study with Robert Koch. He was employed by the military as he received his grants and money from the Prussian army. For each semester of education, he owed 1 year of service as a military surgeon. This accumulated to 2 years, from 1881 to 1883 as he served under the Second Hussar regiment. A lesser known part of his studies was his research in ophthalmology and how he furthered the understanding of the eye and its diseases. He wrote a paper during his time at Wicherkiewicz's hospital in Poznan from 1881 to 1883 on an eye tumor case that ended up with the patient dying from leukemia, but it did allow for much needed research on treatments for the eye and what the preferred pathways for surgery would be.
