Abstract: The focus of the workshop has been laid on the issues of the methodology and didactics of the history of informatics. A special interest has been devoted to contributions which document some aspect of Austria’s role in the field of informatics, or provide insight into the impact of informatics on the Austrian society. Informatics (computer science) is a thriving science yet its brief history is barely credited as an academic discipline. The existing body of historical literature, while small, includes some brilliant contributions, especially biographical and technological chronicles, as well as some excellent anecdotal treatments. Nevertheless, the methods and didactical approaches for examining the history of informatics are poorly developed; the number of conferences and journals dealing with these issues is few, as is the number of young scientists doing scientific research on the history of informatics. This is not because these topics are uninteresting or irrelevant; rather, the conditions for methodically well-founded research are lacking. The motivation of MEDICHI 2007 has been to contribute towards making the ‘history of informatics’ an accepted science and a valued component of Informatics education and research. Each submitted paper has been reviewed by 3 members of the program committee. From 12 submitted papers, 8 have been accepted as a full and 2 as a short paper to be presented. Additionally, 5 invited position papers, written by members of the program committee and 4 invited keynote talks have been presented in altogether 8 sessions. Each presentation is published in the proceedings at hand. The MEDIHCI 2007 workshop was also the venue for awarding the prizes of the 2007 Wolfgang von Kempelen Prize for Computing Science History. The organizers thank to all participants for their contributions and wish the reader an exiting tour through the proceedings
