Swimming has been a sport at every modern Summer Olympics. It has been open to women since 1912. Swimming has the second-highest number of Olympic medal contested events after athletics.
Swimming is an individual or team racing sport that requires the use of one's entire body to move through water. The sport takes place in pools or open water. Competitive swimming is one of the most popular Olympic sports, with varied distance events in butterfly, backstroke, breaststroke, freestyle, and individual medley. In addition to these individual events, four swimmers can take part in either a freestyle or medley relay. A medley relay consists of four swimmers who will each swim a different stroke, ordered as backstroke, breaststroke, butterfly and freestyle.
Freestyle is a category of swimming competition, defined by the rules of the International Swimming Federation (FINA), in which competitors are subject to a few limited restrictions on their swimming stroke. Freestyle races are the most common of all swimming competitions, with distances beginning with 50 meters and reaching 1500 meters, also known as the mile. The term 'freestyle stroke' is sometimes used as a synonym for 'front crawl', as front crawl is the fastest surface swimming stroke. It is now the most common stroke used in freestyle competitions.
The women's 4×100 metre medley relay event at the 1964 Olympic Games took place on 16 October (qualification) and 18 October (final). This swimming event uses medley swimming as a relay. Because an Olympic size swimming pool is 50 metres long, each of the four swimmers completed two lengths of the pool, each using a different stroke. The first on each team used the backstroke, the second used the breaststroke, the third used the butterfly stroke, and the final swimmer used freestyle.
The men's 100 metre freestyle event at the 1948 Olympic Games took place between 30 and 31 July at the Empire Pool. There were 41 competitors from 19 nations.

The event was won by Wally Ris, returning the United States to the podium in the event after a one-Games absence broke a seven-Games streak. It was the sixth victory for an American in the 100 metre freestyle, most of any nation. Another American, Alan Ford, took silver. Géza Kádas of Hungary earned bronze, the nation's third medal in four Games. Japan's three-Games medal streak in the event ended with no Japanese swimmers competing due to the nation not being invited after World War II.
