The data used to create the web site that you are accessing is the product of years of work by a group of dedicated Olympic historians and statisticians. The group that has compiled the database refers to itself as MADmen — MAD being an acronym for several of the members of the group, but also signifies their commitment to the project in another sense. The group consists of Hilary Evans (GBR), David Foster (GBR), Martin Frank (GER), Arild Gjerde (NOR), Jeroen Heijmans (NED), Martin Kellner, Bill Mallon (USA), Wolf Reinhardt, Ralf Regnitter (GER), Paul Tchir, Magne Teigen (NOR), and Christian Tugnoli, with some assistance from Herman De Wael (BEL) and Ove Karlsson (SWE). All of them are members of the International Society of Olympic Historians (ISOH), with Mallon a past-President, and have been working on compiling databases of complete Olympic results and a database of all Olympians for many years.
In the late 1990s, they found each other via e-mail and discovered that they were independently working on the same, or at least very similar, projects. Since about 1998, they have worked together, and the database used to create the web site you see now is probably the product of about 60 man-years of work.
Since 1998, the method of their work has been for each of them to work on various aspects of the database and then send the work out for editing to all of the others. In this way, they believe they have compiled the most complete and most accurate database of Olympic athletes yet known.
