John Berkeley James Wells: marine biologist, environmentalist; b October 6, 1935; d November 12, 2018

Professor John Wells, who has died aged 83, was a research scientist, family man and community leader. He was a man of his time, surviving World War II, progressing to a career that stretched around the world.

He became the first full-time dean of science at Victoria University of Wellington, was an international authority on the biology of tiny harpacticoid copepod crustaceans, and made a significant contribution to the conservation of the Pauatahanui Inlet.

John Berkeley James Wells was born on October 6, 1935, in Hammersmith, west London. His father and mother ran a small newsagent, stationers and tobacconist shop, above which they lived. At the beginning of World War II, John and sister Joan were evacuated separately to villages outside London. They returned home near the end of the war when it was thought to be relatively safe, only to be bombed out by a V-1 flying bomb (doodlebug) that exploded near their shelter, blasting the door open, and throwing John out of his bunk, while his mother received massive facial bruising.

His father was on duty that night as an ARP warden. The shop and ground floor of their home survived, but the entire floor above was blown off into the street. The single storey that was left was quickly reroofed so the shop could reopen. In the meantime, they lived with friends across the street.

In 1946 John received a scholarship to Latymer Upper School in Hammersmith, where he began to specialise in science subjects. A keen swimmer, he became captain of the school swimming and water polo teams. He joined Penguin Swimming Club, competing in county and national events. John's interest in swimming led to his meeting his future wife, Margery, at Ealing Swimming Club. They married on September 26, 1959.

In 1951 he could have taken School Certificate but, as students had to be 16 by October 1, he was six days too young and was forced to repeat the year before sitting the exams. In the sixth form he studied biology, chemistry and physics whilst also developing a passion for classical music and eventually opera. He began BSc studies at the Central Polytechnic in 1955 and graduated in 1958 with first-class honours in zoology. He began study for a PhD in marine biology at Exeter University in 1958, and graduated in 1961.

His first job was as a temporary assistant lecturer in zoology in the final year of his PhD. From then his career took him to a position as assistant lecturer at Birkbeck College, University of London (1961-63) with a secondment to University College of Rhodesia and Nyasaland in Salisbury. He then was appointed to a lectureship at Aberdeen University

In 1976, Wells and his family emigrated to New Zealand, where he was appointed professor of zoology at Victoria. During this time, he taught introductory zoology; elementary, advanced undergraduate and postgraduate courses in invertebrate zoology, marine biology and ecology, population and evolutionary biology, and systematics and taxonomy. He also supervised honours, masters and doctoral students in marine biology and ecology. He was also a trustee of the Karori Wildlife Trust (more latterly Zealandia).

His interests outside his career were extensive. He was a keen golfer and avid home handyman, and made much of the furniture for the family home. He and Margery were long-time subscribers to the New Zealand Symphony Orchestra and Chamber Music concert series.  But he was never too busy to take his two boys fishing, to the library, watch them play sport, and teach or explain to them, with great patience, the workings of just about anything.

In 1991, Wells became the first full-time dean of science at Victoria, a position he held until 1998. During that time, he amalgamated the departments of zoology, botany, and biochemistry into a School of Biological Sciences – a difficult process involving staff losses and considerable stress. His ability to handle all the issues with tact, fairness, decisiveness, and vision ultimately made the amalgamation a success. He insisted that technical staff and senior students share morning and afternoon tea with the academics; this one move did much to unify the school.

Wells was known internationally as a pre-eminent authority on the biology of harpacticoid copepod crustaceans, tiny creatures that live among sand grains. His 215-page Keys to aid the identification of marine harpacticoids was, and remains, a classic reference volume. He also authored about 50 scientific papers in the general areas of marine biology, marine ecology and the taxonomy of harpacticoid copepods.  He conducted field work around the world, and was a visitor at the University of South Carolina in 1982, where he collaborated with close colleague Professor Bruce Coull, resulting in five publications.

He retired from Victoria in 2001. In retirement he donated his own collection of harpacticoid copepods and related materials to the existing collection at Te Papa, making it one of the best research collections in the world.

He became a trustee of the Pauatahanui Inlet Community Trust in 2003, and a founding trustee of the Porirua Harbour and Catchment Community Trust in 2012. In each of these roles, he brought a broad scientific understanding to discussions and decisions, and encouraged new students to engage in understanding the importance of looking after our estuaries.

He became chairperson of the Guardians of Pauatahanui Inlet from 2004 to 2013. Under his leadership, the guardians have been the major organisation promoting community awareness, gathering data and co-ordinating community involvement in the environmental protection of Pauatahanui Inlet. This work has been particularly appreciated by employees of the Porirua City Council, since Wells spoke with gravitas borne of his wealth of knowledge, wisdom and respect with which he was held in Porirua Harbour restoration circles. He was known as polite, patient and respectful, and a real gentleman. When he was excited or happy, he had a twinkle in his eye and a smile that would light up a conversation.

He was recognised in the 2013 Porirua Civic Awards for his outstanding voluntary service to the Porirua community, guidance to members, and the wider public.

Wells, who died of motor neuron disease, is survived by his wife, their two sons David and Stephen, partners Celia and Rachel, and grandsons Logan and Oliver.
