Robert H. Grubbs (1942-2021)

American chemist born in Kentucky, professor at the California Institute of Technology (Caltech) from 1978.

In the 1990s he developed the ruthenium metathesis catalysts that bear his name, stable to air and compatible with most functional groups, which turned metathesis into a general method in organic synthesis and polymer chemistry. He received the 2005 Nobel Prize in Chemistry with Yves Chauvin and Richard R. Schrock.
