ahead of larger West Germany. This was improved upon at five winter games, with 4 second-place rankings and a first in the 1984 Winter Olympics. It is widely believed that doping (predominantly anabolic steroids) allowed East Germany, with its small population, to become a world leader in the following two decades. It won a large number of Olympic and world gold medals and records. A number of athletes subsequently failed doping tests and others were suspected of taking performance-enhancing drugs. However, in many cases where suspicions existed, no proof of wrongdoing was uncovered. As a result, the majority of records and medals won by East German athletes still stand. Aside from an extensive doping programme, East Germany invested significantly in sport, particularly in Olympic sports, for reasons of prestige, propaganda and rivalry with West Germany. It had an extensive state bureaucracy to select and train promising athletes and world-class coaches. An important figure in the GDR was Manfred Ewald (1926–2002), member of SED central committee from 1963. He was president of the "Staatliches Komitee für Körperkultur und Sport" (Stako) from 1952 to 1960. In 1961, he became president of the "Deutscher Turn- und Sportbund" (DTSB), governing all sport in the GDR, and in 1973 president of the NOC. He is considered to be the organiser of the "GDR sports miracle". His post-1990 autobiography was titled "I was the Sport". He fell from grace in 1988, having been removed from the office of DTSB. In 2001, he was found guilty of doping. Germany reunited The German Democratic Republic ceased to exist in 1990, joining the West into a reunified Germany in the process of German reunification. Accordingly, the "NOC of the GDR" joined the "NOC of Germany" on 17 November 1990. German athletes competed at the Olympic Games as a single team again from 1992 onwards. Athletes from the Eastern part of Germany contributed disproportionately to the medals won by Germany, particularly in the first decade after reunification. This is thought to indicate that doping was not the only reason East Germany was so successful (and more successful than West Germany in particular) in the Olympics, with professional training conditions also being significant. The medal tally of reunited Germany after 1990 was more comparable to that of East Germany before 1990 than of West Germany before 1990. For example, of the twenty nine medals Germany won in the 2006 Winter Olympics
