Memorial Page for Ernst Otto Fischer

Ernst Otto Fischer (born 10 November 1918 in Solln near Munich; died 23 July 2007 in Munich) was a German chemist. In 1973 he received the Nobel Prize in Chemistry together with Geoffrey Wilkinson for pioneering work on the chemistry of organometallic sandwich compounds. His research helped establish organometallic chemistry as a modern field between inorganic and organic chemistry.

Study and wartime interruption

Fischer grew up in Munich; his father was a physicist at the Technical College of Munich. After school, labor service and military service, Fischer began studying chemistry in 1941/42 during a period of study leave. The war interrupted his education. After his release from American captivity, he resumed his studies in Munich, completed them in 1949 and received his doctorate in 1952 under Walter Hieber.

Ferrocene and sandwich compounds

The starting point of the later Nobel work was ferrocene, a newly synthesized compound whose structure was not yet clear. Fischer recognized that an iron atom was arranged between two ring-shaped organic groups. This kind of compound became known as a sandwich structure. Independently, Geoffrey Wilkinson worked on the same questions. The insight opened a new view of metal-carbon bonds and of compounds that were neither classically organic nor classically inorganic.

Munich as a scientific home

Fischer's career remained closely connected with Munich. He worked at the Technical College of Munich, later at LMU, and from 1964 again at the Technical College, which became the Technical University of Munich. There he held the chair of inorganic chemistry. His research went beyond early sandwich complexes, including metal carbonyl, carbene and carbyne complexes. Many later developments in organometallic chemistry and catalysis built on such foundational work.

Nobel Prize

In 1973 Fischer and Geoffrey Wilkinson received the Nobel Prize in Chemistry. The Nobel Foundation cited their independent pioneering work on organometallic sandwich compounds. What mattered was not a single technical process, but a new structural understanding: metals could be built into organic molecular architectures in ways that had previously been difficult to imagine.

Farewell

Ernst Otto Fischer died in Munich on 23 July 2007. His biography stands for research that turned precise structural clarification into a new chemical field. He remained rooted in Munich and shaped inorganic chemistry there for decades.
