he became Principal keeper of the newly opened Bull Point lighthouse. The final appointment of his career was at North Foreland, from where he retired. George was famous for his wonderful models of the lights in which he served. Models of Smeaton's tower, Bull Point and North Foreland still exist. The model of Bull Point is owned by Plymouth Museums. The North Foreland model is in a private collection. He made two models of Smeaton's Eddystone Lighthouse. The models were perfect in every detail, both inside and out. Fortunately, one has been preserved and is on display at the Chatham Historic Dockyard Museum. The other model was for many years on display at Trinity House where it was destroyed in 1941 during the Blitz. Henry Thomas Knott Henry Thomas Knott (born 1851) worked through the replacement of colza oil by paraffin and the consequent replacement of old Argand burners with lamps having multiple wicks and then the even brighter incandescent oil burner which converted liquid oil into vapour before combustion. The life of a lighthouse keeper was a dangerous one. Whilst painting the roof of the Skerries lighthouse, Henry slipped on wet paint and almost somersaulted off the roof onto the rocks some 25 metres (80 feet) below. He managed to save himself when his clothing became hooked onto an iron stay. On another occasion, Henry bravely carried out the rescue of the crew of a small vessel, even though his small rowing boat was in constant danger of itself being smashed onto the rocks. Henry served out many appointments, one of which was a three-year overseas appointment in the extremely remote lighthouse on Minicoy Island in the Indian Ocean. Edmond Horton Knott South Foreland lighthouse was also the site of experiments in radio communication by Marconi from 1898. This coincided with the service of the final member of the Knott lighthouse keepers, Edmond Horton who was keeper from 1899–1902. In March and April 1899, radio transmissions from South Foreland were of great assistance in the distress of at least two vessels on the Goodwin Sands.
