Then World War II changed things once again as whilst a good half of the school was evacuated on 2 September 1939 to Overton Hall, many pupils were left behind in Derby due to shortage of room - two houses were created at Overton Hall called Greens and Atkinsons whilst those left back in Derby were called Hastings and Mellings. Then in June 1940 when Amber Valley Camp was finally completed the whole school was reunited, including those from Derby, when they returned to their pre-war houses Gatelys (A to E of alphabet), Tanners (F to K), Fullers (L to R) and Grimes (S to Z). These names were then retained until Derby School closed down in 1989. Research Report from Old Derbeian Society June 2012 and July 2013.
