Elected FRS 1992
David Graham Lloyd was born on 20 June 1937 at Manaia, Taranaki, New Zealand, slightly ahead of his identical twin brother, Peter. The births caused surprise to the family because twins were not expected. His father was a dairy farmer, and David's early years were immersed in country life and helping on the farm. David's mother died of cancer when he was eight years old and his father brought up the twins, as well as his elder siblings, Judith and Trevor, with the help of their grandparents, who farmed next door. Although the death of their mother was a sad loss, David seems to have had a happy childhood and to have excelled at primary school before moving to boarding school with Peter in 1950. At New Plymouth Boys High School, David was most interested in the sciences and also in sports, for which the school was well known. Although relatively small in stature, he played in the first team at rugby, was a tenacious tackler, and also excelled at sprinting and long jump.
