Jakob Friedrich Ehrhart (4 November 1742, Holderbank, Aargau – 26 June 1795) was a German botanist, a pupil of Carl Linnaeus at Uppsala University, and later director of the Botanical Garden of Hannover, where he produced several major botanical works between 1780–1793. Ehrhart was the first author to use the rank of subspecies in botanical literature, and he published many subspecific names between 1780 and 1789.
In 1779, Carl Peter Thunberg (1743-1828) named a genus of grasses, Ehrharta, in Ehrhart's honor.
If you had a room, he'd paint it white,
survives the day, prefers the night,
build sight.
Got a head for figures,
no time for bickers,
(or so he says,)
prefers the company of a woman.
Finds it more physical,
(that's an important word,)
always seen first then heard,
such a rare bird.
With praise he glows,
with change he grows,
finds that important,
hates waiting, it's not stimulating,
likes celebrating,
I can't understand why that is so funny,
