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.
Miescher had isolated various phosphate-rich chemicals, which he called nuclein (now nucleic acids), from the nuclei of white blood cells in Felix Hoppe-Seyler's laboratory at the University of Tübingen, Germany,[1] paving the way for the identification of DNA as the carrier of inheritance. The significance of the discovery, first published in 1871, was not at first apparent, and Albrecht Kossel made the initial inquiries into its chemical structure. Later, Miescher raised the idea that the nucleic acids could be involved in heredity[2] and even posited that there might be something akin to an alphabet that might explain how variation is produced.[3]
