 Hermann Staudinger - Biography
Hermann Staudinger was born in Worms on the 23rd of March 1881.
Staudinger was educated in Worms, matriculated in 1899, and continued his studies first at the University of Halle, later at Darmstadt and Munich.
Staudinger resigned from his post as Principal of the Chemical Laboratories of the University in April 1951, and accepted the honorary appointment as Head of the State Research Institute for Macromolecular Chemistry, which he held until April 1956.

 Hermann Staudinger - Wikipedia, the free encyclopedia
Hermann Staudinger (March 23, 1881 in Worms - Sept. 8, 1965 in Freiburg) was a German chemist.
In 1934, philosopher Martin Heidegger learnt that Staudinger had applied for Swiss citizenship during World War I, he denounced him to the regional minister of Education as a hidden pacifist.
Staudinger was invited to resign, but he refused and the issue was dismissed because of fears of international outrage.

Staudinger studied chemistry at the universities of Darmstadt and Munich, and he received his Ph.D. from the University of Halle in 1903.
In 1922 Staudinger and J. Fritschi proposed that polymers are actually giant molecules (macromolecules) that are held together by normal covalent bonds, a concept that met with resistance from many authorities.
Staudinger showed that such linear molecules could be synthesized by a variety of processes and that they could maintain their identity even when subject to chemical modification.

 Hermann Staudinger
Hermann Staudinger was born at Worms in Germany on 23 March 1881.
Staudinger introduced the concept of macromolecules, a term which he coined, and polymerisation in May 1922, in a report which appeared in Helvetica Chimica Acta.
In 1953 he was somewhat belatedly awarded the Nobel Prize for the huge contribution he had made to the understanding and development of polymers.

 Foundation Of Polymer Science Named An International Chemical Landmark
Staudinger's pioneering research, first at the Eigenössische Technische Hochschule (ETH) in Zurich, then at the Albert Ludwigs University in Freiburg, led to the development of polymer science as a modern multidisciplinary field of great industrial significance.
Staudinger's initial findings created a stir in the international chemical community when he postulated, in 1920, that materials such as natural rubber have very high molecular weight weights his contemporaries considered gigantic and unlikely.
Staudinger retired from the chemistry department in 1951 and was succeeded by Arthur Lüttringhaus.

 A new way to engineer cells: The Staudinger ligation
Named for the German synthetic-organic chemist Hermann Staudinger, who won the Nobel Prize in 1953 for his pioneering work in polymer chemistry, the Staudinger reaction occurs between an azide and a phosphine, a molecule containing a phosphorus atom.
Staudinger would have loved the challenge!" Bertozzi and Saxon added an electron-hungry carbohydrate trap to the phosphine, which attaches to the electron-rich aza-ylide and prevents it from falling apart in water, subsequently yielding a stable amide bond.
Because the "Staudinger ligation," named by Bertozzi after the classic reaction that inspired it, is potentially useful for labeling components of the cell interior -- such as amino acids from which proteins are assembled -- previously unobservable interactions in the cell may become accessible.

 Polymers: Time Line of Achievement
Starting around 1920, Staudinger argued that natural polymers were made of giant chainlike molecules, rather than aggregates of small molecules that give the false impression of giant molecules.
Staudinger was unpopular in his home country because of his outspoken criticism of Germany’s use of poison gas in World War I, and his ideas were rejected by many in the German scientific community, which at the time supported the aggregate theory.
Staudinger would spend 15 years gathering evidence for his theory and arguing for its acceptance by the scientific community.

 Polymers and People - Science Explains Polymers
Staudinger's ideas may not sound especially radical today, but at the time he was ridiculed by his colleagues in organic chemistry, and his theories had little impact on the scientific community.
Many years later Staudinger was recognized for his efforts and persistence, when in 1953 he became the first polymer chemist to receive a Nobel Prize.
Staudinger's key insights--that polymers are long chains of many small chemical units and that chain length plays a crucial role in determining physical properties and behavior--pointed up the need for tools to assess molecular weight and thus chain length.

Born in Worms, Germany, in 1881 and receiving his Ph.D. from the University of Halle in 1903, Hermann Staudinger had mainly been interested in ketene chemistry, only beginning his investigations of natural rubber in 1910.
Meanwhile, some scientists felt that there was an upper limit to the number of atoms that could be joined together in a single molecule.
Further validation came in 1953 when he was awarded the Nobel Prize in chemistry in recognition of his pioneering work.

After a lecture by Hermann Staudinger, one of the pioneers of the concept of polymers, he was compared by a learned member of the audience to an African explorer who claimed to have seen a zebra 400 feet long.
The methods we now use to analyse polymers were not available in the 1920s, and the polymer concept was only accepted after Staudinger carried out painstaking experiments on the synthesis of oligomers (very small polymers, up to about 20 monomer units) and showed that their properties converged towards those of the large polymer.
Interestingly enough, Staudinger himself was equally dismissive some years later of the first claims that ethene had been polymerised...

It took another German, organic chemist, Hermann Staudinger, to realize that Simon's discovery, comprised of long chains of styrene molecules, was a plastic polymer.
In 1922, Staudinger published his theories on polymers, stating that natural rubbers were made up of long repetitive chains of monomers that gave rubber its elasticity.
In 1953, Hermann Staudinger won the Nobel Prize for Chemistry for his research.

 Polymers
From his experiments with rubber colloids, Staudinger provided evidence for the existence of large molecules, which he called "macromolecules." Staudinger also showed that smaller molecules (monomers) could be combined to form long chainlike structures (polymers) by chemical interaction and not simply by physical aggregation.
Staudinger won the 1953 Nobel Prize for Chemistry for demonstrating that polymers are long-chain molecules and his work provided the theoretical basis for polymer chemistry.
It is interesting to note that in the 1930s Staudinger voiced his beliefs on the important role that macromolecules played in living systems, especially proteins.

It was Hermann Staudinger (1881-1965), director of the Institute of Chemistry in Freiburg, who in 1920 set up the studies on the structure and properties of natural and synthetic polymers (cellulose, isoprene).
He disagreed with the current theories on polymers as associated compounds held together by secondary valencies, and proposed, for syntethic polymers of styrene and formaldehyde and for natural rubber, the formula of open chains, which today is accepted by everyone.
Staudinger’s theories were not accepted by everyone and the debate continued into the 1920’s.
