Born in the vicarage in Lenham, Kent, he was the second of the parish priest's three children. He joined The Pilgrim's school, Winchester, in 1932 and became a senior chorister at the cathedral. Three years later, he won the top entrance scholarship to Winchester College, where his precocious talents in mathematics and music flourished. In 1941, he won a scholarship to Balliol College, Oxford, to read chemistry, but at the end of his first year also took part one of the music tripos, and was appointed Balliol organ scholar. In his second year, Christopher performed what Dr John Jones has described as "probably the greatest intellectual feat by a Balliol undergraduate ever": he proposed, with convincing arguments, the correct structure of the chemical compound diborane (B2H6) - a compound that defied contemporary chemical valency principles.
