David Baker was born in New Cross in south-east London in July 1936. He, and his non-identical twin brother Paul, were evacuated from London (as many children were) in 1940 to Hertfordshire, where they remained for nearly five years with just occasional visits from their parents. David told me that his father was a driver in the Army based near Dover and he could sometimes get up to see his sons by borrowing an army vehicle.
Bob was born on 13th March 1933 in Chipping Norton, in 1943 he went to Christ’s Hospital (Thornton A). At school he passed his school certificate in 8 subjects, and higher certificate in physics, chemistry & maths.
