A decision was made on 2 September 1939 for the pupils and staff of Derby School to be evacuated immediately away from the town of Derby due to its proximity of the then Derby Electricity Power Station in Full Street in the centre of Derby. This was followed on the following day by the declaration of war on Sunday 3 September 1939. As a temporary measure from September 1939 until June 1940 they first went to Overton Hall in Ashover near Matlock.
