Which original Dragon's Den investor was born Peter David Jones?

The original Dragon's Den investor born Peter David Jones is Peter Jones.

Peter Jones is a British entrepreneur and businessman who became one of the original investors on the UK version of Dragon's Den. His business interests have included technology, telecommunications, retail and property, giving him a broad commercial background for evaluating pitches.

Jones is especially recognisable on the programme for his tall stature and formal business style. As a dragon, he has considered proposed valuations, ownership percentages, routes to market and the practical ability of founders to scale their companies.

The other names in the question are also strongly associated with the British series. Duncan Bannatyne, Theo Paphitis and Doug Richard were fellow early investors, but none of those names is the answer. Peter Jones has remained one of the programme's longest-serving dragons.
