In 1861 the physiologist Ernst Brücke (1819-1892) published "The Elementary Organisms," calling for a major reform of the definition of the animal cell. An English translation of Brücke's essay is presented here for the first time. In this translation the numbered footnotes 1-9 are Brücke's own; alphabetical endnotes A-HH are my own annotations, with additional references to works cited by Brücke. Figures referenced by Brücke but not included in his original essay are also provided. I have also presented an introductory essay to my translation that provides background on Brücke and his arguments: "The Schema and Organization of the Cell," https://doi.org/10.1007/s10739-024-09774-8 , in this same issue of the Journal of the History of Biology.
