David Gruby

David Gruby (20 August 1810 – 14 November 1898) was a Hungarian physician born in the village of Kis-Kér (now Bačko Dobro Polje, Serbia) to a Jewish farmer.Geoffrey Clough Ainsworth, ''Introduction to the History of Medical and Veterinary Mycology'', Cambridge University Press (2002), p. 13 He received his doctorate in Vienna and performed scientific research in Paris.

Gruby is remembered as a pioneer in the fields of microbiology and medical mycology. Most of his important work was done during the 1840s, when he reported that human disease could be caused by fungi. In 1841 he described the fungus associated with favus, a discovery that was independent of Johann Lukas Schönlein's (1793–1864) findings. Later, the fungal parasite was called ''Achorion schoenleinii'' in Schönlein's honor.

In 1842 he described a microscopic cryptogam (''Trichophyton ectothrix'') that is associated with a dermatological disease known as ''sycosis barbae''. Gruby also discovered '' Candida (Monilia) albicans'', the cause of candidiasis, and in 1843 he described a fungus (''Microsporum audouinii'') that is the cause of a type of ringworm. This fungus was named after naturalist Jean Victor Audouin (1797–1842).

Gruby also discovered a parasite in the blood of frogs he called ''Trypanosoma sanguinis''. During the early years of anaesthesia, he performed important experiments with chloroform and ether on animals.
