Peter Leo Reichertz
Peter Leo Reichertz (* 20. September 1930; † 6. August 1987), actually Hermann Leo-Peter Reichertz [r01], was a pioneer in the field of medical informatics who made a significant contribution to this emerging discipline in its early days [r02], [r03], [r04].

Biography
Peter Leo Reichertz was born in Speicher (Eifel), Germany. Some key dates in his curriculum vitae are [r05], [r06]:
- 1949: High school graduation (German: Abitur) in Trier, Germany.
- 1955: Studies in medicine, mathematics, and physics. Final medical examination (German: Medizinisches Staatsexamen, M.D. equivalent) and attainment of a dissertation-based doctoral degree in Medicine (German: Dr. med) in Bonn, Germany.
- 1956-1966: Physician in the Outpatient Clinic of the Department of Internal Medicine (German: Medizinische Poliklinik) of the University of Bonn.
- 1964: Postdoctoral lecture qualification (German: Habilitation) in internal medicine
- 1965-1966: Chief Physician.
- 1967-1969: Associate Professor and Director, Radiology Computer Research at the University of Missouri, USA.
- 1969-1987: Professor (Associate Professor until 1972 and Full Professor thereafter) and Director at Hannover Medical School.
- 1974: Professorship and Institute renamed to “Medical Informatics” (from “Clinical Data Processing and Documentation”).
During his studies in mathematics and physics, he was introduced early to computers and the programming language FORTRAN.
Accomplishments
Professor Peter L. Reichertz grasped the potential of computers for medicine and health care very early.
Since the early sixties, he perceived information and communication technology and information processing methodology as not merely other technologies such as microscopes or ultrasonic devices, for improving diagnosis and therapy. His vision encompassed the revolutionary potential of informatics for all aspects of biomedicine and health care, with consequences for research and education [r06].
His appointment as professor at Hannover Medical School gave him and his team an outstanding opportunity to implement integrated computer-based application systems in this medical school and university medical center, which included a microfilm-based central medical record archive and a comprehensive patient database integrated with an administrative hospital information system and laboratory information systems. Denoted as Medical System Hannover (MSH), this integrated architectural approach for computer-supported hospital information systems served as a key model for digital patient care from the late 1960ies to the 1980s, and constituted one of the earliest computer-supported integrated hospital information systems in Germany and around the globe [r04], [r07].
Peter L. Reichertz coined the term “Medizinische Informatik” (medical informatics) in Germany (replacing “Medizinische Dokumentation und Datenverarbeitung” and helped to promote the corresponding English term “medical informatics” (replacing medical computer science) [r04]. He also made significant contributions to medical education and education in medical informatics in Germany, which significantly impacted the international concepts and approaches in health informatics and medical informatics education [r09].
Honors
- 1975-1977: President of the German Association for Medical Informatics, Biometry and Epidemiology (Deutsche Gesellschaft für Medizinische Informatik, Biometrie und Epidemiologie (GMDS) [link GMDS]
- 1970-1987: Editorial board member of the journal “Methods of Information in Medicine”
- 1977-1981: Foundation President of the European Federation for Medical Informatics (EFMI), [link EFMI])
- 1983-1987: Foundation President of the German Medical Informatics Professional Association (Berufsverband Medizinischer Informatiker BVMI [link BVMI])
- 1976-1987: Co-editor of the German book series “Medizinische Informatik und Statistik” (medical informatics and statistics) published by Springer-Verlag, Germany
- 1978-1987: Co-editor of the book series “Lecture Notes in Medical Informatics” published by Springer-Verlag, Germany
- 1988: Editor in Chief of the journal “Methods of Information in Medicine” (planned but unfortunately, Atropos, the goddess of fate, stepped in…)
Peter L. Reichertz Institute for Medical Informatics
In 2007, the Peter L. Reichertz Institute (PLRI) for Medical Informatics of TU Braunschweig [link TUBS] and Hannover Medical School [link MHH] was founded, unifying the previously separated Institutes for Medical Informatics at both universities to create a regional cluster of excellence in the field of medical informatics [link PLRI]. With the institute’s name, both universities honored Professor Reichertz as one of the most significant pioneers in medical informatics worldwide [r06]. Today, PLRI has about 80 employees and is one of the major German centers for medical informatics [link PLRI].
In 2019, when hosting the EFMI Special Topic Conference (STC), PLRI celebrated the 50th anniversary of research in medical informatics in Germany with a Peter L. Reichertz Symposium [L1] and an extraordinary EFMI Young Scientist Prize [L2].
