Wyndham Halswelle (30 May 1882 – 31 March 1915) was a British athlete. He won the controversial 400 m race at the 1908 Summer Olympics, becoming the only athlete to win an Olympic title by a walkover.

Born in London to London-born, Edinburgh-trained artist Keeley Halswelle and Helen Marianna Elizabeth Gordon, he is nonetheless usually referred to as being Scottish, the nationality of his maternal grandfather, General Nathaniel J. Gordon. Wyndham Halswelle had a notable athletic career at Charterhouse School and the Royal Military Academy Sandhurst, before being commissioned into the Highland Light Infantry in 1901. While his regiment was in South Africa in 1902 for the Second Boer War, Halswelle's ability was recognised by Jimmy Curran, a coach and former professional athlete. It was he who persuaded Halswelle to take up athletics seriously when his regiment returned to Edinburgh in 1904.

In 1904 he was army champion for 880 yards, and in 1905 he won the Scottish and AAA 440 yard (402 m) titles. In the Athens Intercalated Olympics, he achieved a silver medal in the 400 metres and a bronze in the 800 metres. On his return, in a single afternoon in 1906 at the Scottish championships in Powderhall, he won the 100, 220, 440 and 880 yards races (91, 201, 402, 805 m), a feat that has not been matched since. His season was cut short by a leg injury in 1907, but he came back the following year to set a world record of 31.2 s for 300 yards (274 m) and a British record over 440 yards of 48.4 s that lasted over a quarter of a century until it was eventually broken by Godfrey Rampling. In 1908 he set a Scottish 300 yards record that lasted until 1961 when it was beaten by Menzies Campbell, then a Glasgow University student.

Eric Henry Liddell ( /ˈlɪdəl/; 16 January 1902 – 21 February 1945) was a Scottish athlete, rugby union international player, and missionary.

Liddell was the winner of the men's 400 metres at the 1924 Summer Olympics in Paris. Liddell's Olympic training and racing, and the religious convictions that influenced him, are depicted in the Oscar-winning 1981 film Chariots of Fire, in which he is portrayed by fellow Scot Ian Charleson.

Eric Liddell, often called the "Flying Scotsman" after the record breaking locomotive, was born in Tianjin (formerly transliterated as Tientsin) (Chinese 天津) in North China, the second son of the Rev. and Mrs. James Dunlop Liddell, who were Scottish missionaries with the London Missionary Society. Liddell was born in 1902 and went to school in China until the age of five. At the age of six, he and his brother Robert, eight years old, were enrolled in Eltham College, Mottingham, a boarding school in England for the sons of missionaries. Their parents and sister Jenny returned to China. During the boys' time at Eltham, their parents, sister and new brother Ernest came home on furlough two or three times and were able to be together as a family, mainly living in Edinburgh.
