Workplaces:	University of Copenhagen Risø
Known For:	Bechgaard salt organic superconductors

Klaus Bechgaard (5 March 1945 – 7 March 2017^[1]) was a Danish scientist and chemist, noted for being one of the first scientists in the world to synthesize a number of organic charge transfer complexes and demonstrate their superconductivity, therefore the name Bechgaard salt. These salts all exhibit superconductivity at low temperatures.

The first organic superconductor was discovered by Bechgaard and Denis Jérome in 1979. This discovery garnered attention in the international scientific community, and for a period he was one of the most cited scientists in the field of natural sciences. He also received a nomination for the Nobel Prize in chemistry for this discovery.

Research

Klaus Bechgaard did research at the University of Copenhagen, where he also held a Professorship in organic chemistry until 1993. From 1993 until 2000 he was the chairman of the Department of Physics and Chemistry at Risø and in 2001 he was appointed head of the newly assigned Department of Polymer Research at Risø. From 2001 and onwards he was the head of Risø's nano technology programme, and The Danish Center of Polymers which is a joint venture between the Technical University of Copenhagen and Risø.

Bechgaard also conducted research in the field of polymers and nano technology at the University of Copenhagen.
