Johannes Friedrich Miescher (13 August 1844 – 26 August 1895) was a Swiss physician and biologist. He was the first scientist to isolate nucleic acid in 1869. Miescher also identified protamine and made several other discoveries.

Friedrich Miescher discovers deoxyribonucleic acid (DNA) in the pus of discarded surgical bandages. Found in the nuclei of cells, Miescher names it " nuclein ". Neurasthenia is first published as a diagnosis in psychopathology by Michigan alienist E. H. Van Deusen of the Kalamazoo asylum [ 2 ] followed a few months later by New York neurologist ...
1869: Friedrich Miescher discovers a weak acid in the nuclei of white blood cells that today we call DNA. In 1871 he isolated cell nuclei, separated the nucleic cells from bandages and then treated them with pepsin (an enzyme which breaks down proteins). From this, he recovered an acidic substance which he called "nuclein". [1]

Friedrich Miescher (1844–1895) discovered a substance he called "nuclein" in 1869. Somewhat later, he isolated a pure sample of the material now known as DNA from the sperm of salmon, and in 1889 his pupil, Richard Altmann , named it "nucleic acid".
The Friedrich Miescher Laboratory (FML) of the Max Planck Society is a biological research institute located on the Society's campus in Tübingen, Germany, named after Friedrich Miescher, founded in 1969 to offer highly qualified junior scientists in biology an opportunity to establish independent research groups and pursue their own line of research within a five-year period.
1869 – Friedrich Miescher identifies DNA in the sperm of a trout. 1871 – Felix Hoppe-Seyler discovers invertase, which is still used for making artificial sweeteners. 1877 – Robert Koch develops a technique for staining bacteria for identification. 1878 – Walther Flemming discovers chromatin leading to the discovery of chromosomes.
