Born Okenfuss, the son of a farmer, he simplified his name to Oken while at medical school in Freiburg, Bavaria. From professor of Medicine at the University of Jena, he soon turned to philosophy & the natural sciences, publishing a controversial journal “Isis” for almost 30 years.
Oken was a prolific & vocal writer, lecturer and theorist, publishing many philosophical treatises during his life. His masterpiece and lasting legacy to the world is the 13-volume “Naturgeschichte für alle Stände” (Natural History for all Social Ranks), first published in 1831.
