Rolf Huisgen

Rolf Huisgen (German: ['huːzgɛn]; 13 June 1920 – 26 March 2020) was a German chemist. His importance in synthetic organic chemistry extends to the enormous influence he had in post-war chemistry departments in Germany and Austria, due to a large number of his habilitants becoming professors. His major achievement was the development of the 1,3-dipolar cycloaddition reaction, also called the Huisgen cycloaddition.

Life

Huisgen was born in Gerolstein in Rhineland-Palatinate and studied in Munich under the supervision of Heinrich Otto Wieland. He completed his Ph.D. in 1943 with a thesis about a strychnine alkaloid.^[1][2] He completed his habilitation in 1947, and was appointed professor at the University of Tübingen in 1949. He returned to the University of Munich in 1952, succeeding Wieland,^[2] and he remained dedicated to research long after attaining emeritus status there in 1988.^[1][3]

One of his major achievements was the development of the 1,3-dipolar cycloaddition reaction, also known as the Huisgen cycloaddition or Huisgen reaction.^[4][5] The Huisgen reaction is of paramount importance to the synthesis of heterocyclic compounds, such as vitamins, alkaloids and antibiotics.^[1]

Huisgen was a member of the American Academy of Arts and Sciences from 1960.^[6] He was also a member of the German National Academy of Sciences Leopoldina and an Honorary Fellow of the Royal Society of Chemistry. He was an Honorary Member of the Gesellschaft Deutscher Chemiker and the Chemical Society of Japan. He was awarded the Liebig Medal in 1961, the Lavoisier Medal from the Société Chimique de France in 1965, and the Adolfo Quilico Medal from the Società Chimica Italiana in 1987, among others.^[7] He was elected to the National Academy of Sciences in 1989.^[8] He received several honorary doctorates, including from the FU Berlin in 2010.^[1]

Sixteen of his students became professors in Germany alone,^[1] including Reinhard Brückner [de], Johann Gasteiger,^[9] Bernd Giese, Herbert Mayr [de], Johann Mulzer,^[10] Hans-Ulrich Reissig, Jürgen Sauer [de] and Ivar Karl Ugi.^[11]

Personal life

His daughter, mathematician Birge Huisgen-Zimmermann, was born in 1946. He died in Munich on 26 March 2020, aged 99.^[7]
