Walter Cornelius (c. 1913–1983) was one of Peterborough’s most colourful local legends. A Latvian-born strongman and stunt performer, he settled in the city after World War II and became famous for his daring – and often eccentric – public feats. These included weightlifting displays, endurance challenges, and, most famously, repeated attempts to “fly” across the River Nene using home-made wings, earning him the nickname The Birdman of Peterborough. Cornelius worked as a lifeguard at Peterborough Lido for many years, where his warmth, humour, and showmanship made him a beloved figure. His mix of athleticism, imagination, and sheer determination secured him a lasting place in the city’s folklore.
