reorganisation of all Haringey Secondary schools into comprehensives. It became Tottenham School. After the County School (1963–present) The Tottenham Green building continued to be used for education in the years since. In 1970 it was used by Moselle school, a special school for children with moderate learning difficulties, until its move to new buildings in Adams Road in 1973. Another new school starting life in this building was Northumberland Park Community School, which opened in 1972. It later moved to new accommodation in Trulock Road, Northumberland Park. Enfield Electronics and Armaments (1901–1918) The history of the Enfield Centre can be traced back to 1901, when Sir Joseph Swan opened the Ediswan Institute in Ponders End High Street for evening classes and social activities. Swan was the co-inventor with Thomas Edison of the electric light bulb and founder of the Edison Swan United Electric Light factory in Ponders End. In 1905 the building was purchased by Middlesex County Council for continuation of evening technical courses. The Institute was extended in 1911 with the opening of new buildings in the High Street and was now called the Ponders End Technical Institute, which included the newly opened day school, the Ponders End Trade School for boys age 13 to 16. The new building included a large electrical testing laboratory and photometric optical room The Institute co-operated closely with the local electricity and gas industries in the provision of day and evening courses for workers in those trades. Another large local employer was the Royal Small Arms Factory at Enfield Lock, an important supplier of small arms to the Government. Many of the apprentices recruited to the armaments factory came from the Trade School and it was in recognition of the demand for well-qualified recruits to the factory that the War Office gave £500 to the Institute for the new 1911 building. Middlesex County Council and Enfield Urban District Council provided the rest. The Trade School offered a two-year course for boys, including basic subjects in year one such as maths, English, history and geography, with mechanical drawing and metalwork. In the second year there were more specialised subjects, such as machine construction, mechanics, magnetism and electricity and building instruction. Enfield Technical College and Junior Technical School (1918–1944) The Trade School became the Junior Technical School after World War One. The Institute was extended in 1924 but the demand for day and evening courses
