ERIC ARTHUR GERALD DUFFEY 1922–2019
On the 10th February 2019, the world arachnological
community received the sad news that the eminent British
arachnologist, ecologist and conservationist Dr Eric Duffey
passed away peacefully in his sleep at the age of 97. Indeed,
he was one of the most elderly living British arachnolo-
gists, standing in a line of such long-lived naturalists and
arachnologists as Jean-Henri Fabre (92, 1823–1915), Pierre
Bonnet (93, 1897–1990), and Alfred Frank Millidge (98,
Eric Duffey was born in Leicester on the 2nd January
1922, from a Swiss father and a Belgian mother. Eric’s
father, Leon Marius Felicien Duffey (1886–1966), was from
a farming family, living in the Vaud mountains, Switzerland.
He entered commerce when he came to England in search
of work in 1911, but loved the countryside and encour-
aged Eric in his interest in natural history. Eric’s mother,
Marcelle Alphonsina Julia van den Bosch (1892–1972), was
a refugee from Antwerp during the First World War. Eric
had two brothers and three sisters, and was the second born.
Only his youngest brother, Fred, survives him.
Eric’s interest in natural history began on family excur-
sions into the Leicestershire countryside, particularly
Charn wood Forest, where his father passed on to him a great
love of trees. As a young teenager, he developed a passion
for birds, and was also fascinated by the diversity of aquatic
life. His rst job on leaving school at 16 was in the Leicester
City Museum where he became adept at mounting birds and
helping in the construction of displays. Realizing that this
was a fairly dead-end job, he joined a team of foresters for
a year, but tree felling in Charnwood Forest was an activity
which he would later deeply regret, when he saw how many
of the ne Leicestershire oak woods had been destroyed
and replaced with conifer plantations. Later, to his credit,
using this unfortunate episode as a starting point, young
Eric undertook a thorough eld study and published his
rst scientic paper devoted to the 11-year succession of
bird populations during the growth of a conifer plantation
(Duffey 1947). While still at the City Museum (1938–1940),
he made enquiries about the formation of a birdwatching
group and, in 1941, became a founder member of the
Leicestershire and Rutland Ornithological Society, still in
existence today with about 600 members.
During World War II, Eric volunteered for the Fleet Air
Arm (FAA) in June 1941 to train as a pilot on aircraft carriers
protecting the North Atlantic eets, and obtained the rank
of Lieutenant in the Royal Naval Volunteer Reserve. He
made good ornithological use of his four-year war service,
recording birds observed while ying, occasionally disap-
pearing from the radar screens much to the annoyance of the
air controllers. His diaries written at that time concentrated
on the birds seen rather than the tactics of ying. He made
contact with an ornithologically minded naval doctor, Surg.
Lt. Neal Rankin, who served on a destroyer protecting the
Arctic convoys. As Bourne (1996: 17) nicely put it, these
“naturalists normally observed their birds over the sights of
a gun”. After the war, he and Rankin compiled a detailed
paper on their joint bird records (Rankin & Duffey 1948).
Eric was discharged from the FAA in July 1945; the ship’s
captain certied that he had served appropriately on HMS
Shrike from 1 September 1944 to 30 July 1945, and had
conducted himself to his entire satisfaction “as a keen and
capable ofcer”. In 1946, Duffey and Rankin helped to
organize the Royal Naval Birdwatching Society, with its
own journal Sea Swallow which started in December 1947
(Bourne 1996). In the following years, Eric published six
papers based on his eld observations on British birds
(Duffey 1950, 1951; Duffey & Creasey 1950, etc.). They
came to the notice of Max Nicholson (1904–2003), the
Director General of the newly formed Nature Conservancy
(now Natural England), a pioneering environmentalist and
keen ornithologist himself, and were perhaps partly instru-
mental in Eric’s appointment in 1952 as its rst Regional
In 1947–1950, he read zoology with botany at Leicester
University College. In 1948, one of his student activities
was to lead an expedition to Bear Island in the Barents Sea
to study birds, terrestrial and marine life (Duffey & Sergeant
1950). During this Arctic eld work, a total of 54 skins of
15 different bird species was collected and deposited in the
Leicester City Museum. After obtaining his B.Sc., Eric went
to Oxford University to study for a Ph.D. at the Bureau of
Animal Population under the direction of Charles Elton
(1900–1991), a prominent zoologist and one of the founders
of animal ecology in Britain, who had the greatest inuence
on his ideas and future research (Sheail 1998). It was Elton
who rst pointed him in the direction of spiders, suggesting
that he went out into the eld to see what might interest him
for his Ph.D. studies (Duffey 1956). Eric was at Oxford in
1950–1952, and continued actively to publish on birds (see

48 Eric Duffey
As an arachnologist, Eric published 99 scientic papers
on spiders, of which over 20 were devoted to faunistics and
taxonomy of British and European spiders, and particu-
larly the spider/invertebrate faunas of Norfolk and Suffolk
(Duffey, Locket & Millidge 1957; Duffey 1959; Duffey
& Morris 1966, etc.), the main areas where his conserva-
tion studies took place. He also published a few papers on
spiders of Spain: e.g., a report on the spider fauna of the Jaca
region (Duffey & Brignoli 1981; Duffey 1983), collected in
1972–1973. A distinctive feature of his faunistic and taxo-
nomic papers is that he always provided detailed data on
habitat preferences of the recorded species, searching for
possible causative factors (moisture, vegetation structure,
and/or microhabitat types, etc.) that could explain their
presence and distribution. From the 1950s to the 1970s,
Eric found and recorded seven spider species that were
new to the British list (Duffey 1953, 1963, 1967; Parker
& Duffey 1963, etc.). Even more importantly, he collected
and described two species new to science: Karita paludosa
(Duffey, 1971) (Linyphiidae) from Ireland (Duffey 1971a:
sub. Carorita p.), and Iberina microphthalma (Snazell &
Duffey, 1980) (Hahniidae) found in chalk grasslands in
Dorset (Snazell & Duffey 1980: sub. Hahnia m.).
A series of Eric’s papers was devoted to aerial dispersal
in spiders, starting from detailed regional observations of
this phenomenon in Berkshire (Duffey 1956) to the factors
inuencing this behaviour (Duffey 1998). He showed that
aerial dispersal seems to be stimulated by overcrowding
and food shortage, but also by physiological factors, among
which thermal conditions during spider development could
be important (see also Bonte 2012).
In his early career, Eric also had a research connection
with the South Atlantic. In 1957, the British Ornithologists’
Union wished to celebrate their 100th anniversary with a
major expedition, and invited members to put forward
suggestions. Eric’s proposal to choose Ascension Island
was accepted and he was able to join the 19-month expe-
dition for three months to study the terrestrial ecology of
the island, while other expedition members concentrated on
the bird life. As a result of this eld work, Eric published a
substantial paper (Duffey 1964a), which provided the rst
comprehensive account on the entire island biota, its history,
and ecology, including checklists of all plant and animal
species recorded from the island to that date (see Ashmole
& Ashmole 1997 for further details). Based on his extensive
invertebrate collections, many new species and genera were
described from Ascension Island (Beier 1960; Cooke 1964;
Ferrara & Taiti 1981; Davis & Mendel 2013, etc.), some
of which were dedicated to Eric: e.g., the ground spider
Prodidomus duffeyi Cooke, 1964 (Gnaphosidae), the pseu-
doscorpion Stenowithius duffeyi Beier, 1960 (Withiidae),
and the terrestrial isopod Niambia duffeyi Ferrara & Taiti,

Being interested in wildlife and its conservation, Eric felt
that the new Nature Conservancy would be an excellent job
choice and, in 1952, he began working as Regional Ofcer
for East Anglia. Arachnology had to take a back seat while
the difcult task of creating and managing National Nature
Reserves and the scheduling of Sites of Special Scientic
Interest was under way. Eric was awarded the Order of the
British Empire (OBE) for these services in 1962, when
he moved to the Nature Conservancy’s new Monks Wood
Experimental Station, where his reputation as a pioneering
conservation research scientist was established. As head of
the Conservation Research Section he led a team of zool-
ogists and botanists working on the conservation ecology
of grasslands and grass heaths (e.g. Duffey et al. 1974). In
addition to work on grasslands, applied ecological research
carried out by his team included a survey of Scottish sand
dunes prior to drilling investigations (Duffey 1968), and
a study of Birmingham Sewage Works, where employees
were being bitten by spiders when there were mass spider
migrations (Duffey 1975b). From an early age, Eric had real-
ized the importance of historical land use, particularly after
attending lectures on the history of the English landscape
by William Hoskins (1908–1992), and talks with Charles
The discovery of Dolomedes plantarius (Clerck, 1757),
one of Britain’s largest spider species, at Redgrave and
Lopham Fen in 1956 (Duffey 1958, 1960a) was particularly
important. By the 1980s, artesian abstraction had desiccated
the Fen and brought the D. plantarius population to the brink
of extinction. Eric’s campaign for funding for systematic
census work kept the conservation spotlight on this species,
and its adoption by English Nature’s (now Natural England)
new Species Recovery Programme in 1991 was the rst step
on a long road to recovery. This combination of rigorous
census methodology and associated research by various
authors (e.g. Smith 2000; Vugdelic et al. 2003; Duffey
2012) on the autecology and conservation management of
D. plantarius, showed how vital a key species could be in
raising awareness of the importance of “sustained manage-
ment of the right kind”, based on scientic criteria (Sheail
2000: 125), for which Eric always appealed in his conserva-
tion programmes and initiatives (e.g. Duffey 1960b, 1971b).
Despite a signicant output on spider faunistics and
taxonomy, Eric’s main interest in spiders over 60 years
concentrated on their habitats and population ecology, a
eld that attracts very few arachnologists. He published over
30 papers on this topic, starting from population studies of
spiders in limestone grassland (Duffey 1962a,b) at Wytham
Woods near Oxford. Methodologically, Eric’s population
studies of spiders always included a detailed description of
the vegetation structure and its microclimate, because both
parameters inuence the composition of the spider fauna.
In his early works, he followed the habitat classication
proposed by his former supervisor, Charles Elton (Elton
& Miller 1954), but later developed his own classication
based “on ecologically signicant features relevant to
spiders” (Duffey 2010: 2), specially for the British fauna.
In his ecological work on spiders, he paid special attention
to historical factors, particularly in the context of man-mod-
ied or articial environments such as sewage treatment
works (Duffey 1975a, 1993, 1997, etc.). Research on the
history of land use is crucial for selecting suitable strate-
gies for conservation of a chosen site, because changes
in management may have contributed to its uniqueness.
Examples include the Norfolk Broads (Duffey 1964a) or
heathlands whose distinctive wildlife cannot be conserved
without appropriate management (Sheail 2000). In order to
draw other arachnologists’ attention to ecological studies,
Eric published a series of papers describing standardized
sampling and recording methods (e.g. Duffey 1972) and
even organized a general discussion on the methodology
of ecological spider research during the Tenth International
Arachnological Congress in Spain (Duffey 1986), in which
16 colleagues from eight countries participated. Some of
the sampling methods advocated by Eric were quite novel
for that time; for instance, vacuum sampling of grassland
spiders (Duffey 1974a, 1980). Eric’s advocacy of the crit-
ical importance of quantitative sampling in arachnology
was pioneering—and something that we still struggle to
achieve! In a nal effort to encourage others to take up the
eld of spider ecology, in 2016 he submitted a number of
his published papers to the University of Leicester, and was
awarded a D.Sc.
In recognition of Eric’s impressive contribution to spider
taxonomy and especially ecology, two new species were

science (Sheail 2000). Eric undertook two tours of European
national parks and nature reserves in thirteen countries (in
the late 1960s and 1970s) and a trip to Australia (in 1989) to
study different practices in conservation research and their
implementation (Duffey 1982). This gave him a wide range
of contacts which he used for developing a broad interna-
tional outlook for the journal. In 1992, he took on the role
of Editor-in-Chief, nally handing over the reins in 1997 to
the English editor, Brian Davis. He also wrote a number of
books and articles on wildlife ecology (e.g. Duffey 1974b).
In 1997, Eric and his wife Rita decided to move to the
Limousin in France, attracted by the more abundant wildlife
and the temptation of y-shing (one of his great loves) in
his own lake. He thoroughly surveyed the spider fauna of
the 8 ha of his land and was one of the main contributors
of new faunistic records to the recently published book
on spiders of the French Limousin region (see Cruveillier
2014: 15). Eric also met Marcel Cruveillier, the author of
that book, to discuss the foundation of a French arachno-
logical society. This came to fruition in 2006 as the Associ-
ation Française d’Arachnologie (AsFrA), with 28 founding
members, which now numbers 102, with an active website
forum. In 2016, AsFrA made Eric its rst honorary member.
He was also an honorary member of the British Arachnolog-
ical Society and the International Society of Arachnology
and, in 1993, was elected as an active member of the Amer-
ican Academy of Sciences. Eric was a past President of the
Elton at Oxford. He felt this to be vital to understanding
nature reserve management, and was the rst to appoint a
historical geographer to his team. Another concept he devel-
oped was that of recreational ecology: the effect of human
leisure activities on the natural environment. The impact
of human activity was paramount in the fens and marshes
of the Norfolk and Suffolk Broads (Duffey 1964b). During
Eric’s time as Regional Ofcer for East Anglia, the Broads
were discovered by Joyce Lambert (1916–2005) to have
been man-made peat cuttings (Lambert & Smith 1960), now
in danger after some 600 years of natural inlling. In addi-
tion to consultations with water authorities and commercial
interests to devise suitable management, Eric organized an
in-depth study of these wetlands with a group of arachnolo-
gists in the 1970s (Duffey & Feest 2009).
In 1974, Eric was invited to become the editor of Biolog-
ical Conservation, a journal that was started by Nicholas
Vladimir Polunin (1909–1997) in 1967. He willingly took
on the task and edited the journal single-handed with the
professional assistance of his wife Rita for 15 years. This
was a labour of love for both of them. Under Eric’s editor-
ship, the journal grew considerably (from four to 12 issues
per year) and allowed him to appoint an Associate Editor
for American papers in 1989. Running the journal was a
wonderful chance for Eric to promote conservation-oriented
research both in the UK and throughout the world, making
the journal a truly international medium for conservation

Throughout all his professional life, Eric collected
spiders and undertook many arachnological eld trips, both
within the UK and abroad. He assembled a large spider
collection, which is now deposited in the Manchester
Museum, as is his archive (223 items, mostly correspond-
ence). When rst donated to the Museum in 2011, the spider
collection contained 138 jars with about 5700 sample tubes,
representing some 560 British and 110 overseas species
(Logunov 2011), together with over 70 jars (some 300
samples) with unsorted and undetermined material from the
Balkans, France, and Spain (Breitling 2018). The collection
was in perfect order, thanks to meticulous curatorial work
by Eric’s wife and trusted companion, Rita. All samples in
this collection are clearly labelled and rich in data, including
detailed habitat information; and all identied samples are
also documented in an electronic database. To date, the
identied part of Eric’s collection has been fully re-curated
and amalgamated with the Museum’s main spider collec-
tion. The undetermined material is still under re-curation
and review, with several scientic papers based upon it
already published (Breitling & Bauer 2015; Breitling 2018)
while others are in preparation. There are also some 20 jars
of unsorted and undetermined British spider material (from
Royston, Hertfordshire: 1973–1975, and later years).
Eric is survived by Rita, his wife of 50 years, his son
Malcolm, daughter Christine, and grandchildren William,
Sophie and James. For fellow arachnologists and a wider
scientic community, Eric Duffey will always be remem-
bered as a pioneer innovator who established a golden
standard on how to approach, scrutinize and resolve scien-
tic and administrative challenges, whether related to spider
taxonomy, conservation science, or both.
I wish to thank sincerely Eric’s widow, Rita Duffey,
for sharing the biographic information on Eric with me,
for answering lots of my questions about him and his life
and for her massive help with the transfer of Eric’s spider
collection and archive to the Manchester Museum. I am also
grateful to John Sheail, Anthony Russell-Smith and Helen
Smith for their comments, helpful suggestions and linguistic
help during the preparation of this obituary.
