In the early 20th century, many Olympic athletes began using drugs to improve their athletic abilities. For example, the winner of the marathon at the 1904 Games, Thomas J. Hicks, was given strychnine and brandy by his coach. The only Olympic death linked to doping happened at the Rome Games of 1960. During the cycling road race, Danish cyclist Knud Enemark Jensen fell from his bicycle and later died. A coroner's inquiry found that he was under the influence of amphetamines. By the mid-1960s, sports federations were starting to ban the use of performance-enhancing drugs. The IOC did likewise in 1967. The IOC created the World Anti-Doping Agency in 1999. The IOC-established drug testing regimen (now known as the Olympic Standard) has set the worldwide benchmark that other sporting federations around the world attempt to emulate. The first Olympic athlete to test positive for the use of performance-enhancing drugs was Hans-Gunnar Liljenwall, a Swedish pentathlete at the 1968 Summer Olympics, who lost his bronze medal for alcohol use.
