Lutz-Dietrich leather
Lutz-Dietrich Leder (born February 12, 1933 in Nordhausen ; † June 5, 2013 in Essen ) was a German pathologist and university professor.
Life
Leder's father was a doctor of economics. Because of his many transfers, Leder attended elementary schools in Weißenfels , Stargard in Pomerania and Weimar from 1939 to 1943 . After two years at the Wilhelm-Ernst-Gymnasium Weimar , Leder's family fled the Red Army to Helmstedt . Leder graduated from high school there in 1954. Since the father was now working at the Federal Statistical Office , the family went to Wiesbaden . There and in Frankfurt am Main, Leder was enthusiastic about the American way of life with entertainment and jazz music. As a gifted guitar and piano player, Leder could have become an entertainer ; but he decided on the "disciplinary medical studies" that he began in 1954 at the Johann Wolfgang Goethe University in Frankfurt am Main . With a doctoral thesis under Karl Lennert , he was promoted to Dr. med. PhD.
He followed Lennert to the Heidelberg University Hospital (1960) and the Kiel University Hospital (1963). In Kiel he devoted himself to hematopathology, in particular the encyhistochemical diagnosis of leukemia . In addition, there was lymph node diagnostics as part of the Kiel lymph node registry, which was founded in 1965 . In 1967 he completed his habilitation in Kiel on monocytes . As early as 1964 he published the fundamental discovery that the naphthol-ASD-chloroacetate esterase reaction can detect neutrophilic myeloid cells and tissue mast cells on formalin-fixed paraffin-embedded tissue . In the USA, the term leather stain was used for this . Leder is also engaged diagnostically and scientifically in the breadth of pathology. Under no circumstances did it want to be labeled as “monocyte leather” in the professional world. Bone tumors were a hobbyhorse . He was soon in international repute and received top list positions in appeal procedures . Henry Rappaport (1913–2003), the leading hematopathologist in the United States , saw leather as the “most prominent personality among German pathologists who have not yet been in a leading position”. Lennert admired Leder's "water-clear mind".
When the "University Clinic of the Comprehensive University of Essen" was planning the West German Tumor Center with the hematologist Günter Brittinger , Leder was appointed to the chair of pathology on October 1, 1975 . He was the first of six Lennert students in external professorships. The institute (with neuropathology and forensic medicine) was housed in a functional new building; but for leather, the working conditions soon became disappointing. 6 out of 18 doctor positions were canceled and the laboratory budget was greatly reduced. There were only 80 places available for 240 students per semester, so that all courses had to be held three times. Funding was even lacking for the case conferences . Work was often done until midnight. In his unconditional truthfulness, Leder showed no consideration for himself or others. For example, in 1979 at a conference in Essen, he tore apart the Kiel classification of non-Hodgkin lymphomas - in the presence of his teacher Lennert, it was a veritable parricide. He refused admission to the German Academy of Sciences Leopoldina - because she had written to him "on GDR paper".
In 1979/80 he was dean . He was legally successful in advocating the secondary employment law of doctors. For many years he designed the pathological questions for the Institute for Medical and Pharmaceutical Examination Questions . “ Jerry Lewis ” - as his students aptly called him - completed a good dozen dissertations and five habilitation theses. The Braunschweig pathologist and art historian Konrad Donhuijsen is one of his students . When non-morphological methods such as the polymerase chain reaction emerged and the “flood of irrelevant publications” swelled, Leder reduced his scientific work. “The increasing standardization of diagnostics and the growing influence of guidelines were perceived by him as a limitation of the diagnostic art. The strong splitting of the diagnosis groups - catalyzed by new techniques - ran counter to his demand for a tumor-biologically oriented diagnosis, which is in vogue today as therapy-relevant individualized tumor diagnosis . He devoted himself increasingly to private interests such as ornithology , music, his favorites Goethe and Schopenhauer and, last but not least, his second wife, an MTA from his institute. As an emeritus (since February 1998) he was teaching children from the neighborhood with great enthusiasm. “The obituary notice of his employees in the Frankfurter Allgemeine Zeitung on June 13, 2013 gives a fitting picture of Leder's personality :
“His love was for nature in its diverse forms. So he trained our morphological eye. He knew how to organize and classify the variability of normal and pathological human tissue without ever forgetting the limitations of this activity. The clarity of his thinking and his language has shaped us all. Long before flat hierarchies and dealing at eye level became the buzzwords of a modern leadership culture, he exemplified this culture for us. "
