Frank Steglich (born 14 March 1941) is a German physicist and the founding director of the Max Planck Institute for Chemical Physics of Solids in Dresden, Germany.
Steglich discovered the first heavy fermion superconductor, CeCu2Si2, while working as a research associate in Cologne, Germany in 1979.
The first published report of the phenomenon occurred in 1979,[2] by which time Steglich had taken up a faculty position at the University of Darmstadt, and confirmed the existence of bulk superconductivity through the measurement of the specific heat anomaly at the transition temperature of Tc=0.5K.
Steglich received the Gottfried Wilhelm Leibniz Prize by the Deutsche Forschungsgemeinschaft in 1986 and a number of other recognitions.
Since 2012 he is distinguished visiting professor at the Institute of Physics, Chinese Academy of Sciences (Beijing) and at Zhejiang University, Hangzhou (China).
