Dr. Joern D. Beck is a retired Professor of Pediatrics and Pediatric Oncology at the Children's Hospital of the Friedrich-Alexander-University Erlangen-Nuernberg, Germany. He graduated at the University of Marburg and Munich.

After his appointment as Physician he worked for two years as a scientific assistant on DNA repair at the Biochemical Institut of the Johannes Gutenberg University Mainz. For his training as pediatrician he moved to the Children's Hospital of the same University and started working also with cancer patients. 

With a grant of the Deutsche Forschungsgemeinschaft he joined 1977 the Memorial Sloan Kettering Cancer Center, New York.  He worked as research assistant in R.A. Good` s group not only  in Immunology and Bone Marrow Transplantation, but he established also  for the Pediatric Department  a program for the classification of leukemic cells, and participated in the therapy of cancer patients.

After almost four years in New York, he went upon invitation to the University of Erlangen developing a team of young oncologists, and setting up at the Children's Hospital a Department for Oncology, Immunology, and Bone Marrow Transplantation, with special attention to children and adolescents with high risk leukemia.

 The team of J.D. Beck introduced also the preparation of hematological stem cells from peripheral as well umbilical blood at the University of Erlangen.

The author worked in many study commissions of the German Society of Pediatric Oncology and Hematology (GPOH) for the development of the oncological front line therapy.

Upon request of this scientific society in 1988 he set up as head of the Late Effects Working group with a team of experts a nationwide follow up program for pediatric and young cancer survivors. This group was developed further to the Late Effects Surveillance System, LESS, which he chaired until 2006, contributing also to the German AWMF guideline, Long-term follow up guidelines after childhood cancer.

In 1990 he was a cofounder of the Early and Late Toxicity Education Committee within the  International I-BFM Study Group, the PanCare network in 2008, later on the European PanCareSurfup  and PanCareLife projects. For the PanCareSurfup project he served as a member of the Ethical and Scientific Advisory Board until 2017.

J. D. Beck was honoured with two awards for his work in late effects research, and survivorship care, respectively.

 The author is deeply thankful for having been a witness of the progress in childhood cancer therapy over the last decades, and feels also a kind of priviliged for having been an active member of a world-wide group of hard-working scientists and care providers, united by the same goals to conquer the scourge of  cancer in the young, ignoring all kinds of differences such as language, nationality, race, or political attitudes.

His legacy for our younger colleagues: 'Hold on tight to your dreams! Even the smallest steps forward may be a source of happiness.'
