It is unusual to write an obituary seven years after the death of a person, but we had only insufficient biographical data about Antoine Senglet until recently. Since we have received several requests for information about him during the last few years (mostly in connection with studies on spiders from Iran), and considering his long-lasting association with the Natural History Museum of Geneva (MHNG) and his remarkable contribution to its arthropod collections, we feel that there is a need to publish a short notice about his life and his scientific achievements.

Antoine Senglet was born on 19 September 1927 in the village of Le Muids (today Arzier-Le Muids), in the French-speaking Swiss canton of Vaud. He was very proud of his “Romand” identity. In his manuscripts submitted to the “Revue suisse de Zoologie” he usually mentioned “Romandie” in his postal address, which the subject editor had to replace with “Switzerland” in order to avoid any possible confusion with “Roumanie = Romania” and because the “Romandie” is not a country but a linguistically defined region. After undergoing primary education, young Antoine attended the “Ecole d'horticulture de Châtelaine” which then was moved to Jussy (also in the canton of Geneva) and became the “Haute école du paysage, d'ingénierie et d'architecture de Lullier”. He subsequently went to work as a horticulturist in England and, when back in Geneva, took up various other jobs, including salesman for vacuum cleaners, pilot of small public boats (called “Mouettes genevoises”) on Lake Geneva, and coalman. The latter he pursued until his retirement in 1993, when he moved to the village of Vich in the canton of Vaud to live in the house of his mother. He had a great interest in zoology, computers and all things technical, and since he received no formal academic education he became an autodidact. When one of us (PJS) first met A. Senglet in 1999, he arrived with a laptop holding a sophisticated self-programmed database (including detailed drawings and photographs of taxonomic characters) on the spider groups he was interested in.

Without the need to sustain a family (he had no wife or children, but a female companion later in his life), A. Senglet usually worked in Geneva in autumn and winter, and then took several months off in spring and/or summer to visit warmer countries and pursue his passion: collecting arthropods. Between 1962 and 1970 he assembled a considerable collection of Odonata from Morocco, Spain, Portugal, France, Italy, Switzerland, ex-Yugoslavia, and Greece. Surprisingly he never published anything on this collection or on other Odonata. In 1978 he sold the collection to the MHNG. He quite abruptly abandoned his interests in Odonata in favour of another, even deeper passion which he pursued for the rest of his life: Araneae. In 1971 he started to publish on faunistics and taxonomy of spiders, later he also turned to mating behaviour and coupling mechanisms between male and female copulatory organs. Between 1967 and 2013 he collected thousands (if not tens of thousands) of spiders in the southern half of Europe (Spain, Portugal, France, Italy, Switzerland, ex-Yugoslavia, Romania, Bulgaria, Greece, Turkey), Morocco, Iran and Afghanistan. In many of these countries he could – and had to – communicate with the locals in their own language. Apart from being francophone, he was fluent in English and Greek, and he had basic knowledge of German, Russian and Persian. In 1973 he made an agreement with Claude Besuchet (1930-2020) and Villy Aellen (1926-2000), former curator of the Department of Entomology 2 and former director of the MHNG, respectively, which provided the financial basis for two extensive collecting trips to Iran in 1973 and 1974, and one to Iran and Afghanistan in 1975. The MHNG purchased the beetles (about half of them meanwhile mounted on cardboard), ants, cockroaches, earwigs, springtails, millipedes, centipedes, mites, pseudoscorpions, and other groups (of which little material is present) that A. Senglet brought back from these trips, and he kept the spiders to himself. It is unclear whether he also collected Opiliones from Iran, a group that is not included in his collection. Three times A. Senglet drove all the way from Geneva to Iran (in these days more open to westerners than at the moment) and back again in a Renault R4, into which he squeezed not only his long legs but also a bed and a refrigerator, and out of which he operated by collecting by hand, with a Winkler/Moczarski eclector and with a backpack aspirator (= suction apparatus). All specimens were preserved in alcohol. The “non-spiders” were sorted and labelled by MHNG staff; the spiders (which he retained) were neatly labelled and separated to families by himself. A considerable portion of the spiders he also identified to species or genus level. In general his material is well preserved, often species are represented by large series from numerous localities, and geographical coordinates are given, which usually allow to identify localities even if their names have changed. When his private collection was donated to the MHNG and arrived on 15 August 2014, it looked overwhelming in terms of volume and specimen numbers, but actually it was all nicely prepared for being incorporated into the spider collection of the museum, a process now complete. Senglet himself published on some of the pholcid spiders he collected in Iran and Afghanistan (besides pholcids, tetragnathids and gnaphosids from the Mediterranean Region). Through the mediation of the MHNG several other colleagues have studied or are currently examining other parts of this collection: Bernhard Huber further pholcids, Andrei Tanasevitch the linyphiids, Dmitri Logunov the salticids, philodromids and some lycosids, and Alireza Zamani & co-authors most of the remaining spiders. Selvin Dashdamirov has studied Senglet's pseudoscorpions from Afghanistan and is currently working on those from Iran; Adrian Smolis & Dariusz Skarzynski published on Senglet's neanurid springtails from Iran; several coleopterologists published on Senglet's beetles from Iran and Afghanistan. Thus, the collections of A. Senglet have proved to be a treasure trove for various taxonomic groups; much has already been published on it – more will hopefully follow in the coming years. His sampling of the previously little-known spider fauna of Iran is of special scientific importance. Alireza Zamani (Tehran, Iran), who is currently working on this fauna for a Ph. D. project at the University of Turku (Finland) and who has examined all Iranian spiders available in scientific collections, rates Senglet's collection, though mostly taken from the northern part of the country, as by far the most extensive and diverse in the world.

Antoine Senglet visited the MHNG whenever he needed to borrow specimens, deposit type specimens that he had described, pick up or bring back specimens which he borrowed from other museums and which were sent to the MHNG, discuss his manuscripts submitted to the “Revue suisse de Zoologie” with the editors, and when he had to take SEM-micrographs.

Back from a collecting trip to Greece in July 2013, A. Senglet suffered a stroke from which he never fully recovered and which left him confined to a wheelchair. He was admitted to a care facility in Yens (canton of Vaud), and when he arrived there he demanded to be allowed to bring along his spider collection. Quite understandably this was refused – it would have completely filled his room. On 29 March 2015 he peacefully passed away listening to his beloved opera music. His body was cremated and his ashes scattered in the garden of his house. He will be remembered by his colleagues, friends and siblings (brother and sister) as a quiet and shy (though occasionally fairly outspoken), rational and dedicated person, and by the arachnological community as an exceptionally prolific collector and as an arachnologist who produced very detailed, high-quality illustrations and descriptions of taxonomic characters (non of his taxa names have so far been synonymized) and genital coupling mechanisms. His scientific legacy lasts on in the collections of the MHNG.


We are very grateful to Lilette Déglon (Morges, Vaud, Switzerland; A. Senglet's sister) and to Claire-Lise Bouquet Studer and Fernand Studer (Combe Varin, Neuchâtel, Switzerland; friends of A. Senglet since 1975) for providing biographical information. The latter two also took care of A. Senglet's spider collection after his stroke. Ivan Löbl (Veyrier, Geneva, Switzerland) kindly sent us a list of beetle species dedicated to A. Senglet and explained his association with the MHNG. Bernhard Huber (Zoologisches Forschungsmuseum Alexander König, Bonn, Germany) sent us a photo of A. Senglet and provided additional information. John Hollier (MHNG) checked the English text.
