RIP Albert Eschenmoser

Via the Twitter account for the chemistry department at ETH Zurich: 

In deepest grief, the Laboratory of Organic Chemistry at @ETH_DCHAB at @ETH_en announces that our friend and colleague, Prof. em. Albert Eschenmoser passed away peacefully, at the age of 97, on July 14, 2023. Albert #Eschenmoser shaped organic chemistry as did few others. 1/3

A brilliant mind gave rise to masterpieces of total synthesis – #Vitamin B12 as a particular landmark in the history of #chemistry – hand in hand w the development of synthetic methods, the unraveling of fundamental mechanistic problems in biosynthesis and organic chemistry. 2/3

His knowledge and interests extended outward from chemistry and the natural sciences to literature, music, and the arts. He was a towering figure in the global success story of @ETH_en and its Department of Chemistry & Applied Biosciences @ETH_DCHAB. He will be sorely missed. 3/3

Best wishes to his family and friends.
