J. Georg Bednorz was bornon May 16, 1950 in Neuenkirchen, North Rhine-Westphalia, Germany, German, is Physicist. J. Georg Bednorz is a German physicist who won a share of the 1987 Nobel Prize in Physics. In collaboration with Swiss physicist, K. Alex Müller, he performed significant work in high-temperature superconductivity in ceramic materials. The son of teachers, he developed an early interest in tinkering with motorcycles and cars. As a teenager, he honed his artistic side and started playing the violin and later the trumpet in the school orchestra. He was also interested in science, and being practical minded, he found performing chemistry experiments to be more interesting than studying the theoretical aspects of physics. He enrolled at the University of Münster to study chemistry but soon shifted to the less popular field of crystallography, a subfield of mineralogy. In 1972, his teachers arranged for him to join the IBM Zürich Research Laboratory for three months as a summer student. It was during this time that he met his future collaborator K. Alex Müller. After completing his graduation and later doctorate, Bednorz joined Müller's ongoing research on superconductivity at the IBM. Their collaboration led to major findings in the field and the duo jointly discovered superconductivity in ceramic materials at temperatures higher than had previously been thought attainable, a work which earned them the 1987 Nobel Prize in Physics.

In 1968, Bednorz enrolled at the University of Münster to study chemistry. However, he soon felt lost in the large body of students and opt to switch to the much less popular subject of crystallography, a subfield of mineralogy at the interface of chemistry and physics. In 1972, his teachers Wolfgang Hoffmann and Horst Böhm arranged for him to spend the summer at the IBM Zurich Research Laboratory as a visiting student. The experience here would shape his further career, not only did he meet his later collaborator K. Alex Müller, the head of the physics department, but he also experienced the atmosphere of creativity and freedom cultivated at the IBM lab which he credits as a strong influence on his way of conducting science.


After another visit in 1973, he came to Zurich in 1974 for six months to do the experimental part of his diploma work. Here he grew crystals of SrTiO3, a ceramic material belonging to the family of perovskites. Müller, himself interested in perovskites, urged him to continue his research, and after obtaining his master's degree from Münster in 1977 Bednorz started a PhD at the ETH Zurich (Swiss Federal Institute of Technology) under supervision of Heini Gränicher and Alex Müller. In 1978, his Future wife, Mechthild Wennemer, whom he had met in Münster, followed him to Zürich to start her own PhD.


In 1982, after obtaining his PhD, he joined the IBM lab. There, he joined Müller's ongoing research on Superconductivity. In 1983, Bednorz and Müller began a systematic study of the electrical properties of ceramics formed from transition metal oxides, and in 1986 they succeeded in inducing Superconductivity in a lanthanum barium copper oxide (LaBaCuO, also known as LBCO). The oxide's critical temperature (Tc) was 35 K, a full 12 K higher than the previous record. This discovery stimulated a great deal of additional research in high-temperature Superconductivity on cuprate materials with structures similar to LBCO, soon leading to the discovery of compounds such as BSCCO (Tc 107K) and YBCO (Tc 92K).


In 1987, Bednorz and Müller were jointly awarded the Nobel Prize in Physics "for their important break-through in the discovery of Superconductivity in ceramic materials". In the same year Bednorz was appointed an IBM Fellow.
