Fritz Kahn

Fritz Kahn (September 29, 1888 – January 14, 1968) was a German Jewish physician who published popular science books and is known for his illustrations, which pioneered infographics.

Fritz Kahn was born in Halle an der Saale, Germany, the son of Arthur Kahn, a physician and author, and Hedwig Kahn, née Schmuhl. His father emigrated to the USA shortly after his birth, settling in Hoboken, New Jersey. Around 1893, after establishing his practise, he sent for his wife and son, and Fritz Kahn started school there. The family later moved to Manhattan, but in 1895 his mother returned to Germany with her three children. They spent time in Hamburg and again in Halle before moving to Bonn with Arthur Kahn after his return from the US, then finally in 1905 moved to Berlin, where Kahn took his Abitur at the Sophiengymnasium; he also served as an instructor in classes for workers.

Kahn studied medicine at the University of Berlin beginning in 1907, passing the state examination to become an M.D. in 1912/13. His studies focused on microbiology, but he also studied a variety of scientific and philosophical subjects, worked at an institute of meteorology, and wrote articles for the popular science magazine Kosmos. From 1914 to 1922 he worked as a surgeon, gynecologist, and obstetrical aide at a clinic.

In World War I he served as a medic, among other postings in Alsace, the Vosges, and Northern Italy. In 1918 he was invalided out on grounds of undernourishment and overwork and was cared for by an Italian farming family. After the war ended, he went to Algeria to recuperate.
