Peter Jones was the youngest original member of Dragon's Den's first investor panel.
The original British panel consisted of Peter Jones, Duncan Bannatyne, Theo Paphitis, Rachel Elnaugh and Simon Woodroffe. Jones was born in 1966, making him younger than the other inaugural Dragons when the series began in 2005.
Jones's early business interests included computers and technology, followed by ventures in media, property and consumer products. His long tenure made him one of the enduring faces of the British programme.
This fact is about the original panel, not every investor who has appeared across the show's history. Later Dragons changed the age range and composition of the panel, so the word “original” is essential to the question.
