Life and work[]

Structure of niacin

Hugo Weidel was born in Vienna in 1849. He studied at the Vienna University of Technology with Heinrich Hlasiwetz. He later moved to the University of Heidelberg, Germany, and obtained a PhD degree there in 1870. After returning to Vienna, Weidel became assistant of Hlasiwetz in 1871. During that time, he started his research on oxidation products of cinchonine and nicotine alkaloids. He became lecturer at the University in 1874, and, after became the chair of the department, Weidel could intensify his research on alkaloids. Although the oxidation of nicotine was already known, Weidel was the first to isolate large enough amounts to determine the properties of the material.^[1] That work earned him the Lieben Prize in 1880.^[2] In 1886, Weidel became professor for agricultural chemistry at the pedology institute in Vienna. Most of his time there was occupied by lecturing and educating students. After the retirement of von Barth in 1891, he returned to his previous institute and assumed a position of full professor. In 1890, Weidel became a member of the Austrian Academy of Sciences and in 1898 he received the Decoration of the Iron Crown of the emperor of Austria. Without any sign of illness, he delivered his lecture on the morning of June 7, 1899, but died after a few hours from a heart problem.^[3]
