Readers: Informatics Studies has just published its latest issue at http://52.205.22.215/index.php/informatics. The current crisis around the Corona virus revealed the importance of Open Access and Open Science - unfettered access to scientific and scholarly information, for scientists, researchers, academicians, journalists and the public alike - for effectively dealing with such calamities. It is the efforts of Sander Dekker during the last decade to implement Open Access by legislation and involvement of European Union; that made it easy for the scientific community to place their research results on Covid-19 under Open Access to arrest the spread of the pandemic. Considering the importance of the contributions of Dekker in the efforts of humanity to sustain life on this planet; the present issue of Informatics Studies is devoted for collecting together historical documents reflecting his work, with two reviews of his career and contributions.
