Duncan Walker Bannatyne, (born 2 February 1949) is a Scottish entrepreneur, philanthropist, and author. His business interests include hotels, health clubs, spas, media, TV, and property. He is most famous for his appearance as a business angel on the BBC programme Dragons' Den. He was appointed an OBE for his contribution to charity. He has written seven books. Early life Bannatyne was born in Dalmuir west of Glasgow. His father Bill had served in the Argyll and Sutherland Highlanders in World War II and worked on the Burma Railway after being captured by the Japanese following the Fall of Singapore, he then worked in the foundry at the Clydebank Singer plant. As a child, he lived in one room with his parents and siblings in a large house shared with six other families. He attended Dalmuir Primary School where he displayed a talent for arithmetic and won a place at Clydebank High School after passing the Eleven plus exam. Most pupils owned a bicycle so he resolved to earn the money to buy one for himself. The local newsagent was not interested in employing him so she challenged him to find 100 new customers in return for a paper round. He called her bluff by returning with 100 names, but later reflected that it would have been more entrepreneurial to have sold the list. He only enjoyed PE and woodwork at the High School and left at 15 without any qualifications. In 1964, after a few weeks working for a local cabinet-maker he joined the Royal Navy, initially enlisting for twelve years as a junior second class engineering mechanic (stoker) at RNTE Shotley near Ipswich, better known as the boys' training establishment HMS Ganges. He served in the Navy for several years including a spell on the aircraft carrier HMS Eagle, before throwing an officer off a boat landing jetty in Scotland and receiving a dishonourable discharge. In his autobiography he claims this was in part a reaction to this officer's abuse of his authority, in part a dare by his shipmates and in part a way of getting out of the Navy, with which he had become disillusioned. Bannatyne was nineteen when this happened. After the incident he had to serve nine months in Colchester military detention centre. He later spent ten days in Glasgow's Barlinnie prison for not paying a £10 fine in relation to a charge of
