Edmond Fischer is a biochemist whose seminal research revealed the role and importance of reversible phosphorylation — the attachment and detachment of phosphate groups to cell proteins — in the regulation of many cellular processes and immune responses.

With his colleague Edwin Krebs, Edmond was the first to purify and detail an enzyme, protein kinase, involved in the phosphorylation process. In acknowledgment of their work in this field, the pair were joint recipients of the 1992 Nobel Prize in Physiology or Medicine.

Edmond has received many other accolades in recognition of his work, including the Werner Prize from the Swiss Chemical Society and the Prix Jaubert from the University of Geneva. He was elected a Fellow of the American Academy of Arts and Sciences in 1972 and a Member of the US National Academy of Sciences in 1973. From 2007–2014, Edmond was the Honorary President of the World Cultural Council.
