37584 Schleiden           Discovered 1990 Oct. 10 by F. Börngen and L. D. Schmadel at Tautenburg.
The German botanist Matthias Jakob Schleiden (1804-1881), a professor at Jena during 1846-1863, utilized the microscope in research and teaching. He stated that cells are elementary units of organisms, and their nuclei are important for the cell division. He was co-founder (with Theodor Schwann) of the field of cytology.
