Ludwig Levin Jacobson

Life

Jacobson - a member of the Jewish religious community - first attended a German lyceum in Stockholm . However, he decided to study medicine, which he completed at the Royal Surgical Academy in Copenhagen . In 1804 Jacobson graduated as CB and MD. In 1806 he was an assistant and in 1807 as a chemistry teacher. From 1807 to 1810 he worked as a tutor at the Royal Veterinary and Agricultural University in Copenhagen.

During the British attack on Copenhagen in 1807, Jacobson served as a military doctor in a Masonic Lodge hospital. After the Danish surrender, his intensive anatomical research began, which earned him the rank of regimental surgeon and a royal scholarship for a research trip through the German states and France. During his stay in Paris he studied practical medicine and surgery. Finally, in 1813, the Danish government even allowed him to get to know the medical care system within the French army. In 1814 - after the Battle of Nations in October 1813 - Jacobson stayed in a field hospital in Leipzig . In the same year he returned to Denmark and received an honorary doctorate for medicine and surgery from the Christian-Albrechts-Universität zu Kiel - the city was temporarily under Danish rule. In 1816 the university appointed him professor. Jacobson was offered a professorship at the University of Copenhagen on condition that he would convert to the Christian faith, which he refused. In a meeting of natural scientists, which was first held in Christiania in 1822 , Jacobson was not allowed to attend because of his Jewish descent, because at the time Norway did not allow Jews to stay in their country. In Denmark Jacobson was a royal personal physician . In 1825 he was elected a corresponding member of the Göttingen Academy of Sciences . and in 1833 elected to the Académie des Sciences .

Act

Jacobson made several anatomical and zoological discoveries named after him:

  • In 1809 he published the discovery of a vomeronasal organ , which is still present in the human nose like an inconsistent rudiment of an evolutionarily older olfactory organ and which has since been called the Jacobson organ. Georges Cuvier reported on this in 1811 in the Annales du Muséum d'histoire naturelle under the title Description Anatomique d'un Organe Observé dans les Mammifères .
  • Jacobson cartilage (Cartilago vomeronasalis)
  • Jacobson anastomosis ( anastomosis between nerve tympanicus and nerve petrosus)
  • Jacobson's plexus ( tympanic plexus)
  • Jacobson's nerve (tympanic nerve)

He also constructed an instrument for lithotrity ( Methodus lithoclastica ), a method for crushing bladder stones . The instrument was further developed by Guillaume Dupuytren .

Honors

  • Around 1811: Silver medal from the Danish Society of Sciences for the discovery of the vomeronasal organ.
  • 1829: Appointed Knight of the Dannebrog Order .
  • 1833: Awarded the Prix ​​Monthyon for his kidney research on birds and reptiles.
  • 1836: Silver Medal of the Order of Dannebrog and honorary member of the Royal Medical Society of Denmark.
