Alderney’s maritime history and heritage

The Channel Islands in Anglo-French Relations, 1689–⁠1918

The Trustees are proud to announce the launch of their very first book – a hansdome production by the Boydell Press which does full justice to the scholarship of the eminent historians who participated in Alderney's first international maritime history Symposium in September 2019.

The book brings together a synthesis of the latest research into several fascinating aspects of the Channel Islands' place in Anglo-French relations, in war and peace, through four centuries.

'Thank you so much for steering the fruits of the conference through to such a fine book, which will bring much delight, not least the memories of our time together in Alderney.' - Captain Michael Barritt

Henry Euler

First Lieutenant Henry Euler RNVR.jpg

Henry Euler, born 1913 in Essex, was a direct descendant of the celebrated Swiss mathematician from Basel, Leonhard Euler (1707-83) – the first great, systematic expounder of the methods of mathematical analysis. Henry’s great grandfather, Heinrich Ludwig Euler, a businessman also from Basel, moved to Bradford, Yorkshire, in 1874, and his father, Leonard Henry Euler, became a director of the new company, Euler & Co.

The Royal Navy

Henry Euler served as a Royal Navy Volunteer Reserve Torpedo Officer in the fleet aircraft carrier HMS Illustrious from the date of her commission and trials in 1939, until March 1941, throughout all of the major naval operations in the Mediterranean until the carrier was severely damaged and withdrawn from service for repairs and a refit at the US Navy Yard, Norfolk, Virginia.

Associate Member

He returned to England, becoming an Associate Member of the Institution of Electrical Engineers, and successfully completing the Long Torpedo Course at HMS Vernon. He subsequently served on the light cruiser HMS Dido, followed by a short period at the Belfast Trawler Base before being reappointed to HMS Vernon for the duration of the Second World War. Prior to release from service, he received a commendation for good service from Commander-in-Chief, Western Approaches.

Director

After returning to civilian life, Henry focused on his career, becoming Director of the Saxonia Electrical Wire Company, specialising in the production of fine wires and cables for the Admiralty and War Office. Henry Euler married Mary Patricia Bracken in 1951. As a married couple, and both keen sailors, they became regular visitors to Alderney in their 7-ton yacht ‘Bonnyrigg II’, always taking a holiday flat above Ralph Duplain’s shop in Victoria Street. They later became members of the Royal Thames Yacht Club.

Mary Euler

Henry Euler died in 1971, after which Mary Euler made plans to move from Wentworth, Guildford, to take up permanent residence in Alderney in 1983. Mary retained a great enthusiasm for all things naval and nautical in connection with Alderney, taking great pride in the annual presentation of the Henry Euler Cup at the Alderney Sailing Club, and later setting up The Henry Euler Memorial Trust. Mary died in 2006. She has made a lasting contribution to the understanding and interpretation of Alderney’s maritime heritage.
