The data used to create the website 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 early members of the group, but also signifies their commitment to the project in another sense. The group consists of:
| Adriano Brunelli |  |
| Sven Buren |  |
| Andrey Chilikin |  |
| Hilary Evans |
|
| José Daniel Faria |  |
| David Foster | |
| Rob Gilmore |  |
| Arild Gjerde |  |
| Jeroen Heijmans | |
| Carl-Johan Johansson † |  |
| Taavi Kalju |  |
| Martin Kellner |  |
| Rudolf Laky |  |
| Kristof Linke |  |
| Connor Mah | |
| Bill Mallon |  |
| George Masin | |
| Ian Morrison |
|
| Jason Moulton |
|
| Stein Opdahl | |
| Ralf Regnitter |
|
| Wolf Reinhardt | |
| Diego Rossetti | |
| Ralph Schlüter | |
| Patrick Secchi |  |
| David Tarbotton |  |
| Paul Tchir |
|
| Magne Teigen † | |
| Morten Aarlia Torp | |
| Michele Walker | |
Most 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 website you see now is probably the product of about 250 person-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.
