Heinrich Otto Wieland was an eminent German scientist who won the 1927 Nobel Prize in Chemistry for his investigations of the constitution of the bile acids. In these days, when scientists tend to specialize from the very beginning his encyclopedic knowledge in all branches of chemistry fill us with wonder. He was probably one of the last academics who had the entire subject on the fingertips. Known as the father of biochemistry he made a number of astounding discoveries covering a wide range of subjects. Among them, Wieland became best known for his work on bile acid. It not only brought him Nobel Prize but also played a key role in explaining metabolism as well as structure of steroids, which in turn helped to develop number of drugs, including the contraceptive pills. However, he shied away from limelight all through his life and consequently not many people remember his name today. In fact, he was first to synthesize arsenical diphenylaminechlorarsine. But, because his discovery did not get much notice, it was named Adamsite after Roger Adam, who worked on it much later. Heinrich Otto Wieland was also a very good human being and risked his own life to save his Jewish students from the Nazis.
