Commemoration of the Cell Theory

Nature volume 143, page 727 (29 April 1939) | Download Citation



THE hundredth anniversary of the discovery of the cell by Th. Schwann is being commemorated this year in many countries. There seems, however, to be a mistake about the date of this great discovery. Schwann's “Mikroskopische Untersuchungen” bears the date 1839; but the first two—and I think the most important—parts of the book had already appeared in 1838. The edition must have been very small, for I have seen only one copy of them during the last twenty years. Schwann placed the 1838 edition before the Paris Academy of Sciences. At all events we are, I think, late in our commemoration.
