Hermann Staudinger’s zodiac sign is Aries. According to astrologers, the presence of Aries always marks the beginning of something energetic and turbulent. They are continuously looking for dynamic, speed and competition, always being the first in everything - from work to social gatherings. Thanks to its ruling planet Mars and the fact it belongs to the element of Fire (just like Leo and Sagittarius), Aries is one of the most active zodiac signs. It is in their nature to take action, sometimes before they think about it well.
Hermann Staudinger was born in the Year of the Snake. Those born under the Chinese Zodiac sign of the Snake are seductive, gregarious, introverted, generous, charming, good with money, analytical, insecure, jealous, slightly dangerous, smart, they rely on gut feelings, are hard-working and intelligent. Compatible with Rooster or Ox.
Staudinger was born in 1881 in Worms. After receiving his Ph.D. from the University of Halle in 1903, Staudinger qualified as an academic lecturer at the University of Strasbourg in 1907.
In 1907, Staudinger began an assistant professorship at the Technical University of Karlsruhe. Here, he successfully isolated a number of useful organic compounds (including a synthetic coffee flavoring) as more completely reviewed by Rolf Mülhaupt.
In 1912, Staudinger took on a new position at the Swiss Federal Institute of Technology in Zurich, Switzerland. One of his earliest discoveries came in 1919, when he and colleague Meyer reported that azides react with triphenylphosphine to form phosphazide (Figure 2). This reaction – commonly referred to as the Staudinger reaction – produces a high phosphazide yield.
While at Karlsruhe and later, Zurich, Staudinger began research in the chemistry of rubber, for which very high molecular weights had been measured by the physical methods of Raoult and van 't Hoff. Contrary to prevailing ideas (see below), Staudinger proposed in a landmark paper published in 1920 that rubber and other polymers such as starch, cellulose and proteins are long chains of short repeating molecular units linked by covalent bonds. In other words, polymers are like chains of paper clips, made up of small constituent parts linked from end to end (Figure 3).
In 1926 he was appointed lecturer of chemistry at the University of Freiburg at Freiburg im Breisgau (Germany), where he spent the rest of his career. In 1927, he married the Latvian Botanist, Magda Voita (also shown as (German: Magda Woit), who was a collaborator with him until his death and whose contributions he acknowledged in his Nobel Prize acceptance. Further evidence to support his polymer hypothesis emerged in the 1930s. High molecular weights of polymers were confirmed by membrane osmometry, and also by Staudinger’s measurements of viscosity in solution. The X-ray diffraction studies of polymers by Herman Mark provided direct evidence for long chains of repeating molecular units. And the synthetic work led by Carothers demonstrated that polymers such as nylon and polyester could be prepared by well-understood organic reactions. His theory opened up the subject to further development, and helped place polymer science on a sound basis.
Staudinger’s groundbreaking elucidation of the nature of the high-molecular weight compounds he termed Makromoleküle paved the way for the birth of the field of polymer chemistry. Staudinger himself saw the potential for this science long before it was fully realized. “It is not improbable,” Staudinger smartly commented in 1936, “that sooner or later a way will be discovered to prepare artificial fibers from synthetic high-molecular products, because the strength and elasticity of natural fibers depend exclusively on their macro-molecular structure – i.e., on their long thread-shaped molecules.” Staudinger founded the first polymer chemistry journal in 1940, and in 1953 received the Nobel Prize in Chemistry for “his discoveries in the field of macromolecular chemistry.” In 1999, the American Chemical Society and Gesellschaft Deutscher Chemiker designated Staudinger's work as an International Historic Chemical Landmark. His pioneering research has afforded the world myriad plastics, textiles, and other polymeric materials which make consumer products more affordable, attractive and fun, while helping Engineers develop lighter and more durable structures.
