Early life and education
Lennert was born in Fürth, which is now contiguous with Nuremberg, in Bavaria. After graduating from high school there, Karl attended medical school from 1939 to 1945 at the Friedrich-Alexander Universitat of Erlangen (now the University of Erlangen-Nuremberg). After World War II, Lennert remained in Erlangen until 1950 as a resident physician in the Institute of Pathology. After another year of postgraduate study at the Max Planck Institute for Biophysical Chemistry in Göttingen, he joined the department of pathology at Johann Wolfgang Goethe University in Frankfurt-am-Main. There, under the direction of Professor Arnold Lauche, he began his lifelong study of hematopoietic diseases, with emphasis on malignant lymphomas.
In 1963, Lennert was asked to chair the Institute of Pathology at Christian-Albrechts-University (CAU) in Kiel. This was a prestigious appointment, because at that time, 75% of department chairs at CAU were the sons of prominent Professors of Medicine in Germany. His students included Reza Parwaresch, Martin-Leo Hansmann, H.J. Radzun, Alfred Feller, Hans-Konrad Müller-Hermelink, and Peter M. Banks. Lennert worked closely with clinicians in the Collaborative Research Centre 111 of the German Research Foundation, principally represented by Drs. Arnulf Thiede and Wolfram Sterry. Lennert was the founding president of the European Association of Hematopathology. In 1989 he became a Professor Emeritus in Kiel.
Kiel Classification System for Lymphomas
