Radar helped fighters to intercept German aircraft
A plaque is being unveiled at Malvern College commemorating the school's role in the Battle of Britain.
Malvern College is only the 20th in the country to be given a plaque by The Battle of Britain Historical Society
Seven pupils from the school took part in the Battle of Britain, two of whom were killed.
Their relatives, including some who have travelled from Canada, will attend the ceremony, on Sunday, 19 September.
They were traced by former pupil, housemaster and deputy head George Chesterton, 87, who also served with the RAF as a bomber pilot, and took part in Operation Market Garden.
The plaque will be unveiled by Air Vice Marshal Peter Millar.
Radar played a vital role in the Battle of Britain
In the 1940s, the school was taken over by the scientists who were working on the development of radar.
The Telecommunications and Radar Establishment was moved to Malvern from Swanage, on the south coast, to keep it safe from German bombing raids.
Many of the schools buildings were used for the experimental work, including the cricket pavillion.
