Bernhard Carl "Bert" Trautmann, OBE (born 22 October 1923) is a German former professional footballer who played for Manchester City from 1949 to 1964. Brought up during times of inter-war strife in Germany, Trautmann joined the Luftwaffe early in the Second World War, serving as a paratrooper. He fought on the Eastern Front for three years, earning five medals including an Iron Cross. Later in the war he was transferred to the Western Front, where he was captured by the British as the war drew to a close. One of only 90 of his original 1,000-man regiment to survive the war, he was transferred to a prisoner-of-war camp in Ashton-in-Makerfield, Lancashire. Trautmann refused an offer of repatriation, and following his release in 1948 he settled in Lancashire, combining farm work with playing as goalkeeper for local football team St Helens Town.

Performances for St Helens gained Trautmann a reputation as an able goalkeeper, resulting in interest from Football League clubs. In October 1949 he signed for Manchester City, a club playing in the highest level of football in the country, the First Division. The club's decision to sign a former Axis paratrooper sparked protests, with 20,000 people attending a demonstration. Over time he gained acceptance through his performances in the City goal, playing all but five of the club's next 250 matches.
