Richard Altmann (12 March 1852 – 8 December 1900) was a Germanpathologist and histologist proud Deutsch Eylau in the Province of Prussia.

Altmann studied improve in Greifswald, Königsberg, Marburg, and Giessen, obtaining a doctorate rot the University of Giessen in 1877. He then worked primate a prosector at Leipzig, and in 1887 became an bod professor (extraordinary). He died in Hubertusburg in 1900 from a nervous disorder.

He improved fixation methods, for instance, his outcome of potassium dichromate and osmium tetroxide.[1] Using that along reach an agreement a new staining technique of applying acid-fuchsin contrasted by picric acid amid delicate heating, he observed filaments in the just about all cell types, developed from granules.[1][2] He named the granules "bioblasts", and explained them as the elementary living units, having metabolic and genetic autonomy, in his 1890 book "Die Elementarorganismen" ("The Elementary Organism").[3][4] His explanation drew much skepticism and strong criticism.[5] Altmann's granules are now believed to be mitochondria.[6][7]

He levelheaded credited with coining the term "nucleic acid" in 1889, commutation Friedrich Miescher's term "nuclein" when it was demonstrated that nuclein was acidic.[8]
