William Nigel Bonner, known as Nigel, was born in London in 1928. He was the child of Frederick John Bonner and Constance Emily (née Hatch) Bonner. Later in their lives, Nigel became a respected zoologist, and
Gerald Bonner became a noted Early Church historian and scholar. Following in his elder brother's footsteps, he also received a County Scholarship to the
Stationers' Company's School in Hornsey, where he was educated. In 1939, the school was evacuated to
Wisbech for several years, due to
World War II. During this time, he was lodged with a slaughterman, which may have contributed to his later "matter of fact" approach to collecting large animals for scientific research. While in Wisbech he showed an early interest in natural history, by collecting beetles. This interest was supported by one of his schoolmasters, By the time he joined the Army for
National Service, in 1946,
World War II was over. In 1947, he was commissioned into the Royal Artillery, and stationed on the
Isle of Wight. There, he continued to pursue his budding zoological interests, by studying beetles, dragonflies and adders. He was demobilized in 1948. After leaving the Army, he worked as a lab technician, and then studied biology at the Polytechnic of North London, as preparation for further education. In 1950, he entered
University College London to study special zoology. Here, Bonner met
J.B.S. Haldane, who was one of his instructors. In 1955, he worked with
Richard John Harrison, a noted anatomist, who assisted Bonner in processing his Antarctic fieldwork. ==Initial work in Antarctic==
