Dr Ken Trethewey is a pharologist with more than fifty years experience. Since 1965 when he discovered he was descended from the famous Knott family of lighthouse keepers, he has been researching pharology - the study of lighthouses. Ken's activities with the National Maritime Museum and his contributions to Wikipedia have greatly helped to bring the Knott family history to the attention of the public.
In 1992 he co-founded the Lighthouse Society of Great Britain that continued until 2005.
From 1994 Ken became one of the first to publish lighthouse material on the internet. This work is brought together in the Pharology group of websites that you can find here.
In the mid-1990s, with his brother Clifford, he built a database of lighthouse keepers, which enabled family history researchers in their quest for information about family members who had served in lighthouses. This is still a part of his work today.
In 1998 he published the first Lighthouse Encyclopedia on CD-ROM, which lasted in eight editions until 2005, and created the first database of world lighthouses, much of which has now been reproduced elsewhere.
In 2002 Ken worked with the world famous lighthouse photographer Jean Guichard to produce the book North Atlantic Lighthouses.
With his rich heritage in lighthouse keeping, Ken wrote a book entitled The Keepers that detailed his family history at South Foreland lighthouse and the Eddystone.
Ken's latest project is a series of books on Pharology. It will fulfil a lifetime ambition. Whilst there are many beautiful books about modern lighthouses, there is no definitive work on Pharology. Ken intends to fill this void. His first volume is called, "Ancient Lighthouses And Other Lighted Aids To Navigation" and is now available from Amazon or via the Jazz-Fusion Books Website. It is the first work of its kind to fully analyse the origins of lighthouses. It contains the most comprehensive study of the Pharos of Alexandria yet published in English.
Professionally, Ken is retired marine engineer specialising in corrosion and materials engineering. Based in Cornwall UK, he has written books about corrosion engineering, lighthouses and jazz. When he is not pursuing his interest of pharology, he now operates his own publishing business, Jazz-Fusion Books.
In 2014, Ken published a book by Gerard Taylor entitled, "But For Ireland, I'd Not Tell Her Name." Lavishly illustrated with Gerard's beautiful art, the story blends the history of the Irish people during the times of trouble with a touching story of love and folklore in the region of Lismore in Co. Waterford. The book is available from your local Amazon website (search under Gerard Taylor) or the Art section of the Jazz-Fusion Books Webstore.
