Knowra Richard Willstätter Richard Willstätter Richard Willstätter was a German organic chemist whose studies of plant pigments, especially chlorophyll, earned him the 1915 Nobel Prize in Chemistry.
Adolf von Baeyer : Adolf von Baeyer was a German chemist whose structural studies of organic compounds earned the 1905 Nobel Prize in Chemistry. Willstätter completed his doctoral work under Baeyer at the University of Munich.
Chlorophyll : Chlorophyll is a family of green pigments that absorb light for photosynthesis in plants, algae, and cyanobacteria. Its composition and relation to other pigments were central subjects of Willstätter's research.
Nobel Prize in Chemistry : The Nobel Prize in Chemistry is an annual international award recognizing major contributions to chemistry. Willstätter received the 1915 prize for his investigations of plant pigments, especially chlorophyll.
University of Munich : The University of Munich is a public research university in Munich, Germany, founded in 1472. Willstätter studied and later taught chemistry there, developing much of his research on plant pigments.
Arthur Hantzsch : Arthur Hantzsch was a German chemist known for research on heterocyclic compounds and stereochemistry. Willstätter worked with Hantzsch at the University of Zurich before establishing his own research program.
Porphyrin : Porphyrins are macrocyclic organic compounds built from four pyrrole-like units and capable of binding metal ions. Willstätter's degradation studies helped establish the porphyrin-like framework of chlorophyll.
Plant physiology : Plant physiology is the study of how plants function, including their growth, metabolism, and responses to the environment. His chemical account of pigments supplied plant physiology with molecular evidence about photosynthesis.
University of Zurich : The University of Zurich is a public research university in Zurich, Switzerland, founded in 1833. Willstätter held his first professorship there after working with Arthur Hantzsch.
Heinrich Wieland : Heinrich Wieland was a German chemist whose research on bile acids and other natural products won the 1927 Nobel Prize in Chemistry. Wieland followed Willstätter as a leading investigator of natural products and succeeded him in Munich.
Magnesium : Magnesium is a chemical element whose ions serve as cofactors in many biological molecules and reactions. Willstätter's work established magnesium as a defining metal component of chlorophyll.
