On the 80th Birthday of Jan van Bemmel

On November 17, 2018 Jan van Bemmel had his 80th birthday. Because of Jan van Bemmel’s role in our medical informatics discipline the idea arose to invite a number of close colleagues to write a contribution in which, when possible, they would review one or more papers of Jan van Bemmel using the knowledge about medical informatics we have today. A number of topics were suggested: about medical informatics as a scientific discipline, about his contributions with respect to ECG analysis and evaluation, about information systems, and about his role in medical informatics education. The contributions of Reinhold Haux (section 2), Johan van der Lei (section 3), Marion Ball (section 4) and Arie Hasman (section 5) review some of Jan’s publications on the before mentioned topics. In addition, contributions about his international collaboration and communication and his work as an editor of the IMIA (International Medical Informatics Association) Yearbook of Medical Informatics and of Methods of Information in Medicine were included. These latter contributions were written by Alexa McCray (section 6) and Dieter Bergemann (section 7). We end this paper with congratulations to Jan van Bemmel
