Born in Clerkenwell on 11 April 1857 and studying medicine at St Thomas' Hospital, Maddick became a doctor and later a surgeon in the Royal Navy.
Maddick claimed to have ‘produced all the films up to and including the Battle of the Somme’, and to have been ‘on land and at sea under enemy fire; as well as in aeroplanes and airships’.
He constructed an unusual mausoleum at West Norwood Cemetery approximately ten years before he died.
The building is nearly 40 ft high in white Portland stone surmounted by a marble figure of Christ and a child.
He directed that the pin given him by King George V should be on his breast and that his jewellery be placed in a box given him by the Japanese Imperial household and buried with him.
