I was familiar with the Tangye name when I worked for Robert M. Douglas
in George Road. The Civil Engineering company often wrote letters to the
Tangye factory. It was a very successful business.
Years later I came across Derek Tangye's books. He was the grandson of Richard Tangy, founder of the Birmingham company. He and his wife
Jeannie (maiden name same as my married name...Nicol) gave up prestige jobs to move to a very small clifftop farm to grow daffodils, keep donkeys and cats. The dwelling they lived in was very basic for amenities in the beginning. Jeannie worked as a PR person at The Savoy Hotel is London and met and wrote about the famous people she met in four books. Derek was a print journalist in the war years and there have been suggestions he worked for MI5.
I have read all Dereks' books and listened to some on tape. They are called the "Minack Chronicles" as a group. Jeannie died in 1986 and Derek lived on another ten years until l996. The cottage and land has been preserved as was their wish and the donkeys are provided for.
