Duncan Bannatyne founded the leisure company Bannatyne Group and became a dragon on the British television show Dragons' Den.
Bannatyne built businesses in several sectors, including care homes, hotels and health clubs. The Bannatyne Group became particularly associated with health and fitness clubs and spas, making it one of the most recognisable businesses linked to his name.
He was part of the original Dragons' Den panel when the British version began in 2005. His background gave him practical experience in growing businesses, managing physical sites and assessing consumer services. These experiences shaped the way he questioned entrepreneurs about costs, operations and expansion.
Peter Jones and Theo Paphitis were also dragons, but neither founded the Bannatyne Group. The company name itself provides a useful clue, although the programme's ensemble of investors means viewers sometimes attach one dragon's business interests to another.
