Richard Altmann (12 March 1852 – 8 December 1900) was a German pathologist and histologist from Deutsch Eylau in the Province of Prussia. Altmann studied medicine in Greifswald, Königsberg, Marburg, and Giessen, obtaining a doctorate at the University of Giessen in 1877. He then worked as a prosector at Leipzig, and in 1887 became an anatomy professor (extraordinary). He died in Hubertusburg in 1900 from a nervous disorder. He is credited with coining the term "nucleic acid" in 1889, replacing Friedrich Miescher's term "nuclein" when it was demonstrated that nuclein was acidic.

He then worked as a prosector at Leipzig, and in 1887 became an anatomy professor (extraordinary). He died in Hubertusburg in 1900 from a nervous disorder. He improved fixation methods, for instance, his solution of potassium dichromate and osmium tetroxide. Using that along with a new staining technique of applying acid-fuchsin contrasted by picric acid amid delicate heating, he observed filaments in the nearly all cell types, developed from granules. 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"). His explanation drew much skepticism and harsh criticism. Altmann's granules are now believed to be mitochondria. He is credited with coining the term "nucleic acid" in 1889, replacing Friedrich Miescher's term "nuclein" when it was demonstrated that nuclein was acidic. (en)

  • Richard Altmann (12 de março de 1852 - 8 de dezembro de 1900) foi um patologista e histologista alemão. Estudou medicina e recebeu doutorado na Universidade de Giessen, em 1877. Posteriormente, ele foi um dissecador em Leipzig, e em 1887 tornou-se um professor de anatomia.Ele morreu em 7 de Dezembro de 1900 em em 1900 a partir de um distúrbio nervoso. Altmann é conhecido pelo seu trabalho envolvendo estrutura e teoria das células. Em seus estudos de células animais, ele investigou pequenos grânulos no protoplasma da célula. Ele melhorou os métodos de fixação, por exemplo, sua solução de dicromato de potássio e textroxide de ósmio e desenvolveu uma técnica histológica que consiste em ácido pícrico, anilina e ácido fucsina e é utilizada para colorizar mitocôndrias em carmesim contra um fundo amarelo. Associado essa técnica de aplicação de ácido-fucsina contrastado por ácido pícrico em meio de aquecimento delicado de coloração, ele observou filamentos a quase todos os tipos de célula, desenvolvido a partir de grânulos. Ele nomeou esses grânulos de "bioblasts" e explicou serem organismos elementares que tinham autonomia metabólica e genética. Hoje as "bioblasts" são conhecidas como mitocôndrias. Em 1890, Altmann publicou seus achados em um tratado chamado Die Elementarorganismen (Os organismos elementares), a explicação dele atraiu muito ceticismo e duras críticas da comunidade científica. Altmann também é creditado pela cunhagem do termo "ácidos nucleicos", ele obteve a nucleína com auto grau de pureza e assim pode comprovar a sua natureza acida dando-lhe então a nomenclatura de acido nucleico, substituindo assim, o termo "nucleína" de Friedrich Miescher (1844-1895).

  • Рихард Альтман (нем. Richard Altmann; 12 марта 1852 — 7 декабря 1900, Губертусбург) — немецкий анатом и гистолог. Профессор Лейпцигского университета. Рихард Альтман учился в Грайфсвальде, Кенигсберге, Марбурге и Гессене, где ему было присвоено звание доктора медицины в 1877 году. Затем он был помощником и прозектором в Лейпциге. Альтман был одним из учёных, подготовивших своими работами создание модели двойной спирали ДНК. В 1889 году Альман впервые ввёл термин «нуклеиновая кислота», тогда же им был разработан первый удобный и общий способ выделения нуклеиновых кислот, свободных от белковых примесей. Умер в 1900-м году от нервного расстройства после шести лет болезни. (ru)
