Terry Erwin’s race to document arthropod diversity inspired taxonomists, systematists, ecologists, evolutionary biologists, and the conservation community at large, as his curatorial work of more than 50 years at the Smithsonian’s National Museum of Natural History and prolific publication record attests. The biography compiles public records, publications, as well as personal memoirs to describe the context in which Erwin’s studies with carabid beetles evolved as formalization of concepts, such as biological diversity, megadiverse countries, biodiversity loss, and conservation biology, will become central for science in the upcoming years. Awareness to explore new frontiers such as the forest canopy and Erwin’s studies in tropical forests, his easy-going personality, and dedicated mentoring attracted colleagues, students, and the general public, making him one of the leaders of tropical biology in the world.

Terry’s early exposure to nature was nurtured by his outdoorsy family and his surroundings. He grew up in the small town of Vallejo, California, located in the region of the San Pablo and San Francisco Bays, the Coastal Redwood forests, the Napa Valley, and the Sierra Nevada. Terry (and sisters Jeani and Toni) spent his childhood summers camping and fishing with his grandfather in the magical world of Giant Sequoia forests, an experience that inspired his sense of self and wonder of nature (Fig.
Terry’s mother, June Gephardt, was a government clerk, and his father, Ed Erwin, worked at Mare Island Shipyard building submarines during WWII and the Cold War. Ed was also a racing car driver in the California circuit and Terry quickly followed in his footsteps, building his own hot rod at the age of 12 (Fig.
As a child, Terry enjoyed comics with stories of superheroes saving the world; later on, he became an avid reader of the stories and adventures of explorers and naturalists. When he discovered the book “The Naturalist on the River Amazons” (
After finishing high school (1961) in Vallejo Junior College, Terry required some collegiate wanders to find his call to biology, but once found it, he was determined to succeed in his studies. He worked at the Mare Island Shipyard to put himself through college, a dangerous job as in those years, many asbestos-containing products were incorporated into the construction and repair of war submarines and other navy vessels. Asbestos was not known to be toxic until the middle part of the 1970s and he undoubtedly had some exposure. Fortunately for Terry, life took him into a career away from the shipyard. In 1963, Terry married his school sweetheart La Verne Magarian, who was a supportive companion throughout his graduate studies and early career, until their divorce in 1980.
Crucial to Terry’s education was the guidance of gifted and insightful professors with whom he shared his curiosity for the natural world and a passion for studying beetles and mentoring. He earned his B.Sc. (1964, Biology) and his M.A. (1966, Biology) degrees from San Jose State College (now San Jose State University) under the guidance of Professor J. Gordon Edwards, whom Terry credited with inspiring his interest in beetles. Edwards, a coleopterist and professional mountain climber, was the ultimate natural history teacher (Fig.

By the time Terry started his professional life as Associate Curator of Coleoptera, the Smithsonian had become a vibrant educational and cultural institution and was at the peak of its growth due to the vision of Secretary S. Dillon Ripley (
By 1975 Terry had conceived a project to explore the forest canopy, one of the richest but least well known and understood environments of the planet, using the fogging technique to collect canopy arthropods (
In 1976 Terry organized the 1st International Symposium of Carabidology in Washington DC, as part of the activities of the XV International Congress of Entomology (
In 1979, Terry had the opportunity to revive his boyhood dream of visiting the Amazon rainforest, but now as a beetle specialist in the new “Minimum Critical Size of Ecosystems Project (now The Biological Dynamics of Forest Fragments Project) under the lead of Tom Lovejoy. This was a collaborative effort between the Smithsonian Institution and the Instituto Nacional de Pesquisas da Amazônia (
In 1979, Terry also embarked on a new project in the Amazon. Encouraged by his colleague and friend David Pearson (then a professor at Pennsylvania State University), he visited the Explorer’s Inn, one of the first ecolodges on the Tambopata River in southeastern Peru. The site had attracted several tropical biologists such as Al Gentry from the Missouri Botanical Garden and Gerardo Lamas from the Museo de Historia Natural San Marcos (Lima, Peru), both of whom would set world records for the number of plants and butterfly species found in one single locality based on data from the Amazon. Also, in Tambopata Terry met legendary ornithologist Ted Parker from Louisiana State University with whom he shared his love of observations of birds, his other natural history hobby in addition to beetles. Gentry, Parker, Lamas, and Terry, among others later, have established Tambopata Explorer’s Inn as one of the best sites for comparative biodiversity and ecological research in the Amazon. At the time, however, the logistics of doing research in remote locations were cumbersome and chaotic. There was no reliable communication with the outside world from Tambopata, particularly during the rainy season when bad weather caused flight cancellations and resulting shortages of supplies that could limit research for days or even weeks at a time. Working there was a difficult task on a limited research budget. In 1985, after a devastating fire in the central building of the lodge, a season’s worth of Terry’s valuable insect collection, field notes, and equipment burned despite the efforts of everybody present at the station.
Terry, Gentry, and Parker would later reunite in St. Louis, Missouri in 1992, when Terry took a sabbatical year while I was doing my M.S. at the University of Missouri at St. Louis. Every Friday afternoon, Gentry held an open botany class at the Missouri Botanical Garden that everyone attended, including Terry and Ted. After the session, the “beer hour” was announced by loudspeaker in a recorded message translated to every language in the world and many informal but highly stimulating science discussions ensued. Terry and I also much enjoyed the opportunity to observe birds with Ted on the weekends. Unfortunately, a plane accident took the lives of Gentry and Parker in 1993 while they were searching for a new locality for the Rapid Assessment Program from Conservation International. The sense of loss hit us hard, but overall, the botanical, ornithological, and conservation communities were devastated.
Terry dramatically expanded our concept of terrestrial insect diversity with the publication of “Tropical forests: their richness in Coleoptera and other arthropod species” (
During the 1980’s the study of biological diversity had steadily picked up momentum and publications regarding species diversity, deforestation rates, species extinction, and fragmentation were abundant. Furthermore, both the scientific community and the general public began to appreciate the close linkage between conservation and economic development. In this context, in 1986, Walter G. Rosen, from the National Academy of Sciences, and Edward W. Bastian, from the Smithsonian Institution, organized ‘The National Forum on Biological Diversity’ (Washington, D.C., 21–24 September). Terry and 70 other leading participants converged at this session, bringing huge scientific expertise, interdisciplinary commitment, and conservation concern to the forum (
During 1986, Terry was appointed Director of the Biological Diversity in Latin America Program (BIOLAT), a new initiative of the Smithsonian Institution and the United Nations Educational, Scientific and Cultural Organization (UNESCO) (Miller in
In 1994, Terry did some environmental impact studies at the Onkone Gare Station in Yasuní National Park, Ecuador, one of the last high-biodiversity protected areas in the western Amazon (

Terry’s commitment to students was a priority in his life, he never missed an opportunity to participate as invited professor in field courses for the Organization for Tropical Studies (OTS) in Costa Rica and Peru; or to serve as external advisor in graduate student committees (Riley; Maveety; Zamorano; this volume). Through his students he developed associations with many universities in the US and overseas. Terry was always eager to provide opportunities for young scientists, hosting interns and fellows at the Department of Entomology at the Smithsonian, sponsoring them to attend meetings and conferences, and trying to connect them further according to their interests (Simms; Garner; this volume). He really believed he stood on the shoulders of giants and kept reaching down and pulling up younger scientists to stand on his shoulders (Neisbitt in
Terry’s fogging technique for collection of canopy arthropods was pretty spectacular. He appeared in National Geographic and the Discovery Channel documentaries, that he later recommended to film director, Steven Spielberg, when asked for advice about the first sequence of the movie “Arachnophobia”. The movie not only recreated very well the fogging of trees in a tropical forest, but they actually replicated the clothes Terry was wearing … right up to the pink bandana around the neck! (Fig.

Terry’s publication about the “30 million species” reached the public in unexpected ways. Gary Larson a popular cartoonist, produced a couple of single-panel cartoons published in newspapers in the 1980s that built on this theme (Fig.
As characterizes any good taxonomist, Terry considered that species were not just names, points on an evolutionary tree, nor abstract sequences of DNA, but rather encode the results of countless millennia of complex interactions and processes. To understand the diversity of life on Earth, and the true rate at which species are disappearing, Terry started by naming each new carabid falling from the canopy. Describing and naming species is the first step to unlock, through additional scientific work, the details about their biology, evolutionary relationships with other species, and a functional understanding of the complex tropical ecosystem. Naming species is a serious business in its own right, but it does not mean taxonomists cannot have some fun doing it, particularly if they are sharp and witty. Terry collected so many new species that after he arranged them in groups for revision, he could dedicate them through their names to scientists (e.g., the genus Batesiana to Bates, Agra eowilsonii to E. O. Wilson, etc.); professors (e.g., Bembidion edwardsi to J. G. Edwards, the genus Geballusa to G. E. Ball, etc.); friends (e.g., Brachinus kavanaughi to D. Kavanaugh, Valeriaaschero to Valeria Aschero), family (e.g., Agra grace to me), and collecting localities (e.g., Asklepia pakitza, to the Pakitza station in Manu National Park, Asklepia biolat to the BIOLAT project, the genus Inpa to the Instituto Nacional de Pesquisas da Amazonia, Hyboptera tiputini to Tiputini Biological Station, etc.). He also accepted suggestions from colleagues and used plays on words (e.g., Agra cadabra, Agra vation, etc.) (Steiner, this volume). In his search for new and unique names, he started dedicating species to stars in movies such as Titanic (Agra katewinsletae to Kate Winslet), Armageddon (Agra liv to Liv Tyler), or just to emphasize a physical attribute (Agra schwarzeneggeri to Arnold Schwarzenegger in recognition of the swollen biceps-like middle femora) (Fig.
A Agra katewinsletae Erwin, 2002 dedicated to Kate Winslet from ‘Titanic’. “Her character did not go down with the ship, but we will not be able to say the same for this elegant canopy species, if all the rain forest is converted to pastures” B Agra schwarzeneggeri Erwin, 2002 dedicated to Arnold Schwarzenegger, in reference to the “markedly developed (biceps-like) middle femora of the males of this species reminiscent of the actor’s physique” C scientific names in ‘Ripley’s Believe it or Not’.
Terry’s endless motivation and energy was borne of a sense of wonder, enjoyment, satisfaction, and challenge from his everyday work on the beetle collections. He was very proud to introduce himself as a ‘taxonomist’; however, his contribution to the world of science and conservation of tropical forests went much further than simply naming and counting species. Terry was a pioneer in neotropical conservation biology and canopy research. His holistic approach to field biology, with Carabidae at its core, enabled him to understand the relatedness of species as well as the mechanisms that drive the evolution of such incredible diversity. Terry’s thoughts will live on in the many scientists, educators, environmental advocates, and nature lovers that he influenced both through direct contact and his scientific work.
