Johann Georg Krünitz (20 March 1728 – 20 December 1796) was a German encyclopedist who started the 242-volume Oekonomische Encyklopädie and during his lifetime managed to complete its first 72 volumes.
From 1747, he studied medicine and the natural sciences in Halle (Saale), Göttingen and Frankfurt (Oder).
After achieving his doctorate with a dissertation called De matrimonio multorum morborum remedio in 1749, he started to practice as a physician in Frankfurt.
Krünitz married Anna Sophie Lehmann in 1752 and moved to Berlin in 1759, where he continued to practice medicine until 1776.
The preface to this posthumously published volume contained the following macabre fact: Already, he had been working on this 73rd edition, and he completed several sheets of it, up to the article 'Corpse'.
