Some decades have slipped by since Bill Kersey became embroiled in the Rennes saga. By 1973 he had acquired many of the special skills essential to tackle this challenge with any hope of success. He grew up during the 1939 to 1945 war years. At that time the family lived in Surrey near London between three airfields and so endured some of the rigours of war. He received his education at the grammar school nearby. Fortunately the language subjects that he studied included both French and Latin. After leaving school Bill spent some time working on Scottish genealogy before serving two years as an armourer in the Royal Electrical and Mechanical Engineers. A year of his service was spent in Libya attached to the 4th/7th Royal Dragoon Guards and 16th/5th Lancers. Much of this time he was working in the desert with the light aid detachment. Leisure activities included exploring the ancient Roman ruins where he was stationed at Sabratha near Tripoli or swimming and diving in the unspoiled Mediterranean sea. Returning to England, he settled into a career in the travel industry with Thomas Cook in London. But travel took him to Rhodesia where he settled with his wife and son and worked for Central African Airways. This included some time spent in Nyasaland as Assistant Senior Sales Supervisor at Blantyre. Again, with time on his hands, Bill served as Diving Officer in the newly-formed Salisbury Branch of the British Sub-Aqua Club, which team achieved the Empire record for fresh water deep diving, using air, in the Sinoia Caves. On the Zambezi Kariba Hydro-electric Dam project, Bill became part of a commercial diving team from the Sub-Aqua Club. Associated Divers undertook all diving work on the project as well as other commercial and police diving. Bill still found time to develop his mineral exploration and mining skills including operating beryllium and alluvial gold claims in Rhodesia. This included rediscovering the lost Woolly Dog gold mine near Bulawayo. When Rhodesia declared itself independent, under the government led by Ian Smith, Bill was working for UTA French Airlines. But when UTA's flights were curtailed due to sanctions he moved to Johannesburg in South Africa with Lufthansa and was later transferred to Capetown. While there, Bill also worked evenings and nights for IBM on the early generation of computers. This skill training stood him in good stead on his return to England. From Capetown he worked his passage to England as a greaser just at the moment that this story begins. With the passage of time, the author has consolidated his computer and engineering skills while working on a wide variety of major petro-chemical, sub-sea, tunnelling and water projects including the Channel Tunnel and the Libyan Great Man Made River project. Petro-chemical and sub-sea projects include Morecambe Gas Field, Liverpool Bay, Whych Farm, and the West of Shetland development. He kept his mineral exploration skills tuned by sourcing the gold and mercury deposits on the Gold Mines River in Ireland. Bill Kersey's planned retirement from projects was linked to his part time work with a publishing house over several years. The purpose of this was to learn the skills he would need to publish and bring into print some of his discoveries in the most exciting of all his projects. Now he has been engaged in more research with Ben Hammott and Sandy Hamblett, the archaeologist with more exciting discoveries.
