The Nobel Prize in Physics 1987
J. Georg Bednorz, K. Alex Müller
I was born in Neuenkirchen, North-Rhine
Westphalia, in the Federal Republic of Germany on May 16, 1950,
as the fourth child of Anton and Elisabeth Bednorz. My parents,
originating from Silesia, had lost sight of each other during the
turbulences of World War II, when my sister and two brothers had
to leave home and were moved westwards. I was a latecomer
completing our family after its joyous reunion in 1949.
During my childhood, my father, a primary school teacher and my
mother, a piano teacher, had a hard time to direct my interest to
classical music. I was more practical-minded and preferred to
assist my brothers in fixing their motorcycles and cars, rather
than performing solo piano exercises. At school it was our
teacher of arts who cultivated that practical sense and helped to
develop creativity and team spirit within the class community,
inspiring us to theater and artistic performances even outside
school hours. I even discovered my interest in classical music at
the age of 13 and started playing the violin and later the
trumpet in the school orchestra.
My fascination in the natural sciences was roused while learning
about chemistry rather than physics. The latter was taught in a
more theoretical way, whereas in chemistry, the opportunity to
conduct experiments on our own, sometimes even with unexpected
results, was addressing my practical sense.
In 1968, I started my studies in chemistry at the University of
Münster, but somehow felt lost due to the impersonal
atmosphere created by the large number of students. Thus I soon
changed my major to cristallography, that field of mineralogy
which is located between chemistry and physics.
In 1972, Prof. Wolfgang Hoffmann and Dr. Horst Böhm, my
teachers, arranged for me to join the IBM Zürich Research
Laboratory for three months as a summer student. It was a
challenge for me to experience how my scientific education could
be applied in reality. The decision to go to Switzerland set the
course for my future. The physics department of which I became a
member was headed by K. Alex Müller, whom I met with deep
respect. I was working under the guidance of Hans Jörg
Scheel, learning about different methods of crystal growth,
materials characterization and solid state chemistry. I soon was
impressed by the freedom even I as a student was given to work on
my own, learning from mistakes and thus losing the fear of
approaching new problems in my own way.
After my second visit in 1973, I came to Rüschlikon for six
months in 1974 to do the experimental part of my diploma work on
crystal growth and characterization of SrTiO3, again
under the guidance of Hans Jörg Scheel. The perovskites were
Alex Müller's field of interest and, having followed my
work, he encouraged me to continue my research on this class of
materials.
In 1977, after an additional year in Münster, I joined the
Laboratory of Solid State Physics at the Swiss Federal Institute
of Technology (ETH) in Zürich and started my Ph.D. thesis
under the supervision of Prof. Heini Gränicher and K. Alex
Müller. I gratefully remember the time at the ETH and the
family-like atmosphere in the group, where Hanns Arend provided a
continuous supply of ideas. It was also the period during which I
began to interact more closely with Alex and reamed about his
intuitive way of thinking and his capability of combining ideas
to form a new concept.
In 1978, Mechthild Wennemer followed me to Zürich to start
her Ph.D. at the ETH, but more importantly to be my partner in
life. I had met her in 1974 during our time together at the
University of Münster. Since then she has acted as a
stabilizing element in my life and is the best adviser for all
decisions I make, sharing the up's and down's in an unselfish
way.
I completed my work on the crystal growth of perovskite-type
solid solutions and investigating them with respect to
structural, dielectric and ferroelectric properties, and joined
IBM in 1982. This was the end of a ten-year approach which had
begun in 1972.
The intense collaboration with Alex started in 1983 with the
search for a high-TC superconducting oxide; in my view, a long
and thorny but ultimately successful path. We both realized the
importance of our discovery in 1986, but were surprised by the
dramatic development and changes in both the field of science and
in our personal lives.
