The Davis Cup weighs more than 100 kilograms, is over one metre tall, and is the world’s oldest sports trophy. It has been filled with champagne in Paris nightclubs, stolen in Peru, and locked in bank vaults during world wars. These days, it is sought after by more than 100 countries every year and known to many as the “holy grail” of men’s tennis. The Davis Cup tournament started in 1889 when four Harvard students decided to test their tennis skills against players in Britain. The prize was neither money nor fame, but simply a silver trophy. Dwight Davis, one of the Harvard students who later became the US Secretary of War, paid $1000 out of his own money to buy the original Davis Cup. It is now worth approximately 600,000 US dollars and is used as the prize for the largest team tournament in the world.
