Heinrich Küchler

Heinrich Georg Küchler (23 April 1811, Darmstadt – 29 March 1873, Darmstadt) was a German ophthalmologist.

From 1828 he studied medicine at the University of Giessen, and following graduation took a study trip to Paris. In 1834 he returned to Darmstadt, where he started a private ophthalmic practice. In 1836 he was unexpectedly arrested because of his actions in association with a Burschenschaft (fraternal organization) at Giessen. For nearly three years he was imprisoned, obtaining his freedom in January 1839. After his release, he resumed his ophthalmic practice in Darmstadt.[1]

In 1844, along with his private practice, he took on additional duties as a physician at the Mathilden-Landeskrankenhaus, a regional hospital in Darmstadt. In 1868 he received the title of Obermedizinalrat (chief medical advisor) and during the Franco-Prussian War (1870–71), he was in charge of a Reservelazarette.[2][1]

In around 1835 he is credited with developing the first symbol eye chart, consisting of figures of various objects (birds, frogs, farm implements, cannons, etc.) cut from calendars and almanacs, of which, he glued to a sheet of paper in decreasing size. Several years later, he issued an eye chart using letters of the alphabet in a graduated series. The chart had twelve lines with the larger letters on the topmost line – also the lines decreased in size to the bottom line. The chart was first published in 1843 and was not widely accepted at the time.[3]

gollark: What I might do, though there are probably many ways to: make a program in Node.js or whatever (personal preference) which responds with whatever image is set to any requests for that, and which allows you to upload an image, converts it to the right format, then saves it to be sent when the ESP requests it.
gollark: And you want to be able to upload pictures to some sort of web thing to send to the ESP?
gollark: That... sounds possible though I don't know exactly what you mean.
gollark: Actually, you could probably just use a static file server and a program to swap out the file every now and then, that would work too.
gollark: Even C, if you're insane.
