Which Dragon's Den investor was known as the founder of the health-club chain Bannatyne Fitness?

Duncan Bannatyne was known as the founder of the health-club chain Bannatyne Fitness.

Bannatyne is a Scottish entrepreneur whose business interests expanded into health clubs, hotels and spas. His fitness company became associated with his surname, making it one of the clearest examples of a Dragon's Den investor being publicly identified with a major consumer brand.

He was one of the prominent early dragons on the British programme. His appearance on the show brought his investment experience to pitches involving consumer products, services and growing businesses.

Bannatyne Fitness should not be confused with the separate businesses associated with Peter Jones, Theo Paphitis or James Caan. Those investors had different commercial backgrounds and panel histories. Bannatyne’s television fame and the fitness chain reinforced each other, but the company existed as part of his wider entrepreneurial career rather than being created by the programme.
