Wilhelm Friedrich von Gleichen
Wilhelm Friedrich von Gleichen-Rußwurm (1717–1783), Stablemaster of the Margrave of Bayreuth, was a German biologist. In 1778 he developed a process of staining micro-organisms with indigo and carmine (Abhandlung über die Saamen - und Infusionsthierchen, und über die Erzeugung, nebst mikroskopischen Beobachtungen des Saamens der Thiere in verschiedenen Infusionen - Treatise on seed and infusoria, and their production, along with microscopic observations of the semen of animals in different suspensions).[1]
The fern genus Gleichenia was named in his honour.

gollark: If you generate random numbers sampled out of the range from 1 to infinity then... 100% minus some infinitesimally small amount are too big to fit in the universe?
gollark: It's not a "99.99999999% chance". We're dealing with infinities here.
gollark: Okay, no, I can think of how you would do that, although not a uniform distribution across the entire range.
gollark: I'm not sure how you would even do that without taking infinite or at least arbitrarily large amounts of time.
gollark: So... *don't* generate random numbers between 0 and infinity?
