1869: DNA First Isolated
1869: DNA First Isolated. Friedrich Miescher isolates DNA for the first time. Miescher, a Swiss scientist, wanted to study the chemistry of cells. He chose to study white blood cells, which are abundant in pus, and were abundantly available to him in bandages from a hospital near his university. Miescher isolated a material rich in phosphorus ...
Friedrich Miescher
Friedrich Miescher (born August 13, 1844, Basel, Switzerland—died August 26, 1895, Davos) was a Swiss student of cell metabolism and the discoverer of nucleic acids. In 1869, while working under Ernst Hoppe-Seyler at the University of Tübingen , Miescher discovered a substance containing both phosphorus and nitrogen in the nuclei of white ...
Friedrich Miescher
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 ...
Friedrich Miescher and the discovery of DNA
Initially, Miescher tried to isolate the cells for his experiments from lymph nodes, but it was difficult to purify the lymphocytes and impossible to obtain sufficient quantities for analysis (Miescher, 1869a).On Hoppe-Seyler's suggestion, Miescher changed to examining leucocytes and obtained the cells for his experiments from the pus on fresh surgical bandages, which he collected from the ...

In the winter of 1868/9 the young Swiss doctor Friedrich Miescher, working in the laboratory of Felix Hoppe-Seyler at the University of Tübingen, performed experiments on the chemical composition of leukocytes that lead to the discovery of DNA. In his experiments, Miescher noticed a precipitate of an unknown substance, which he characterised ...

Within 10 years of their experiments, Watson and Crick deciphered its structure and yet another decade on the genetic code was cracked. However, the DNA story ...
Friedrich Miescher :: DNA from the Beginning
Friedrich's father was a physician and taught pathological anatomy; Friedrich's uncle, Wilhelm His, was a well-known embryologist. Miescher was an excellent student despite his shyness and a hearing handicap. Miescher initially wanted to be a priest, but his father opposed the idea and Miescher entered medical school.
Friedrich Miescher: The Pioneer of Nucleic Acid Discovery
In the annals of scientific history, the name Friedrich Miescher stands tall as a pioneer whose groundbreaking work paved the way for our understanding of the fundamental building blocks of life - nucleic acids. Miescher's fascination with the human body and its composition drove him to study medicine at the University of Basel. However, his ...

From discovering to understanding: Friedrich Miescher's attempts to
Between 1868 and 1869, Miescher worked at the University of Tübingen in Germany (Figs 2,3), where he tried to understand the chemical basis of life.A crucial difference in his approach compared with earlier attempts was that he worked with isolated cells—leukocytes that he obtained from pus—and later purified nuclei, rather than whole organs or tissues.

Rather, DNA was first identified in the late 1860s by Swiss chemist Friedrich Miescher. Then, in the decades following Miescher's discovery, other scientists--notably, Phoebus Levene and Erwin ...
Before Watson and Crick in 1953 Came Friedrich Miescher in 1869
Abstract. In 1869, the young Swiss biochemist Friedrich Miescher discovered the molecule we now refer to as DNA, developing techniques for its extraction. In this paper we explain why his name is all but forgotten, and his role in the history of genetics is mostly overlooked. We focus on the role of national rivalries and disciplinary turf wars ...
Classic experiments: DNA as the genetic material
Apparently DNA was discovered by a Swiss scientist named Friedrich Miescher in 1868, so almost contemperaneous to Mendel. Doesn't roll off the English speaking tongue as easily as Watson and Crick (or Franklin). Also, part of the experiment might be even grosser than fruit flies.

14.1: Historical Basis of Modern Understanding
DNA was first isolated from white blood cells by Friedrich Miescher, who called it nuclein because it was isolated from nuclei. Frederick Griffith's experiments with strains of Streptococcus pneumoniae provided the first hint that DNA may be the transforming principle. Avery, MacLeod, and McCarty proved that DNA is required for the ...
DNA translated: Friedrich Miescher's discovery of nuclein in its
In 1871, the Swiss physiological chemist Friedrich Miescher published the results of a detailed chemical analysis of pus cells, in which he showed that the nuclei of these cells contained a hitherto unknown phosphorus-rich chemical which he named 'nuclein' for its specific localisation. ...

In 1869, Johann Friedrich Miescher discovered a new substance in the nucleus of living cells. The substance, which he called nuclein, is now known as DNA, yet both Miescher's name and his theoretical ideas about nuclein are all but forgotten. This paper traces the trajectory of Miescher's reception in the historiography of genetics.
