Georges Jean Franz Köhler (; 17 April 1946 – 1 March 1995) was a German
biologist
A biologist is a scientist who conducts research in biology. Biologists are interested in studying life on Earth, whether it is an individual Cell (biology), cell, a multicellular organism, or a Community (ecology), community of Biological inter ...

monoclonal antibodies
A monoclonal antibody (mAb, more rarely called moAb) is an antibody produced from a Lineage (evolution), cell lineage made by cloning a unique white blood cell. All subsequent antibodies derived this way trace back to a unique parent cell.

Career
Köhler was born in
Munich
Munich is the capital and most populous city of Bavaria, Germany. As of 30 November 2024, its population was 1,604,384, making it the third-largest city in Germany after Berlin and Hamburg. Munich is the largest city in Germany that is no ...

Laboratory of Molecular Biology
The Medical Research Council (MRC) Laboratory of Molecular Biology (LMB) is a research institute in Cambridge, England, involved in the revolution in molecular biology which occurred in the 1950–60s. Since then it has remained a major medical r ...
in Cambridge, UK where he began working with
César Milstein to develop a laboratory tool that could help them investigate the mechanism that underlies the diversity of antibodies. It was during this work that they devised their hybridoma technique for the production of antibodies. Köhler continued his collaboration on the technique when he returned to
Basel Institute for Immunology in April 1974. Köhler remained at the Basel Institute for another nine years, during which time he continued investigating antibody diversity and in the early 1980s began working on the development of transgenic mice as a tool to understand the mechanism that underlies self-tolerance. In 1986 Köhler became director of the
Max Planck Institute of Immunobiology where he worked until his death in 1995. He died in
Freiburg im Breisgau

Personal life
Köhler's father, Karl, was a German, while his mother, Raymonde, belonged to a French family. He married Claudia Reintjes in 1968. His first meeting with Claudia was held when he was doing university studies while Claudia was a physician's assistant. They had three children: Katharina, Lucia and Fabian. He not only worked hard for refining antibodies but also gave his time to his family. George moonlighted as a taxi driver to support his family. Most of the time he spent with his children while driving a small tractor on roads and enjoying roller-skating in streets.
