TWO unions are in mourning following the deaths last week of Peter Miller, a former president of the Secondary Heads Association, and Alan Manasseh, senior professional officer with the Professional Association of Teachers. PAT general secretary Jean Gemmell said that everyone at the union was "devastated" after Mr Manasseh's sudden death, at only 53, of a heart attack while out cycling with his family. Mrs Gemmell said: "He was an outstanding friend and colleague." Mr Manasseh headed the union's pay and conditions team. Mr Miller became the first deputy head to become president of SHA, in 1996. He chaired the union's public and parliamentary committee for two years. SHA general secretary John Dunford said: "He was incredibly hard working and a very nice man." Mr Miller died from a brain tumour. He was 54.
