He goes on to study Organic Chemistry and earns a PhD in 1947.

During the war years, Fischer studies biology and chemistry at the University of Geneva. 

In 1935, he enters Geneva's all boys’ Collège de Calvin from which he obtains his Maturité Fédérale four years later. Fischer is also admitted to the Geneva Conservatory of Music, studying piano. Music has always played an important part in his life, but he keeps it purely for pleasure.

Edmond H. Fischer is born in Shanghai to Austro/French parents. His maternal grandfather was a French journalist; he later went to Shanghai where he founded the first French newspaper published in China and helped to establish l’École Municipale Française where Edmond first went to school.

He stays on as a researcher until 1953, teaching a course in the budding field of biochemistry.

Edmond Henri Fischer shares the 1992 Nobel Prize in Physiology or Medicine with Edwin Krebs, for describing how reversible phosphorylation works: By adding or removing a phosphate group from a protein, it changes shape enabling it to take part in some biological process. This mechanism regulates many metabolic processes. Krebs and Fischer are the first to purify and characterize one of the enzymes involved in the process, called glycogen phosphorylase.

In that year he fulfills his ambition to go to the United States, initially intending to join Caltech, but instead accepting an invitation to join the faculty at the University of Washington, Seattle. He soon teams up with his colleague Edwin Krebs, and becomes a full professor in 1961.

At age 7, his parents send him and his two older brothers to La Châtaigneraie, a large Swiss International boarding school overlooking Lake Geneva.
