Wieland, Heinrich Otto

Wieland, Heinrich Otto (1877-1957) German chemist who studied the constitution of bile acids, organic radicals, nitrogen compounds, and contributed to the advancement of organic chemistry. He was awarded the 1927 Nobel Prize in chemistry.

Two German chemists, Heinrich Otto Wieland (1877-1957) and Adolf Windaus (1876-1959), each received a Nobel Prize in chemistry (Wieland in 1927 and Windaus in 1928) for work that led to the determination of the structure of cholesterol.

Two German chemists, Heinrich Otto Wieland (1877-1957) and Adolf Windaus (1876- ), worked out the structure of steroids and related compounds. (Among the steroids are a number of important hormones.) Another German chemist, Otto Wallach (1847-1931), painstakingly elucidated the structure of terpenes, important plant oils (of which menthol is a well-known example), while still another, Hans Fischer (1881-1945), established the structure of heme, the coloring matter of blood. 

Heinrich Otto Wieland (Germany) for his investigations of the constitution of the bile acids and related substances. The bile acids are a set of steroid acids whose synthesis begins in the liver with the production of chloic acid chenodeoxycholic acid (all of which derive from cholesterol). Wieland isolated and determined the structure of a number of these biochemically significant compounds. During his career he also isolated toxins from poisonous frogs and mushrooms.

The beginnings of steroid chemistry go back to Adolf Windaus (1876-1959), who laid the foundations of this captivating field in 1905. Important contributions came from Adolf Butenandt (1903-1995) and Heinrich Otto Wieland (1877-1957).

Fischer was a very private person. While he enjoyed company in his younger years, he cultivated real friendship with only very few people, with his cousin Otto, with Ludwig Knorr, his assistant in Erlangen for many years, or with W. Koenigs and later in life with C. Duisberg, both former fellow students. Curtius was similarly an introvert, his personality, as characterized by Heinrich Wieland in an obituary, always clouded under the veil of a certain reservation . This might contribute to our understanding of the distance Fischer and Curtius kept from each other.
