For the latter part of his career he was a member of staff in the Zoology Department of University College London, eventually as professor. His range of zoological knowledge was notably wide, and his main research was on the behaviour of the lugwormArenicola. He determined its habits by elegant experiments, and showed that the rhythm which controls many of its activities arises in the oesophagus. Such spontaneous rhythmic activity was shown to occur in many polychaetes.
He was known to all by his nickname, Gip, and appears by this name in his father's fictional story The Magic Shop. He was elected Fellow of the Royal Society in 1955.
Wells also published the 1971 (and last) edition of his father's The Outline of History in the wake of Raymond Postgate's death in March of that year. Postgate had revised four previous editions following HG Wells' death in 1946, published in 1949, 1956, 1961 and 1969.
