Early life and education
David Tab Rasmussen was born in Salt Lake City, Utah on June 17, 1958 to Deon and David I. Rasmussen. After living briefly in Michigan and California, his family moved to Tempe, Arizona where he grew up. Both his father and grandfather, Daniel Irvin Rasmussen, were biologists. His interest in the natural world and native cultures began during his childhood with his exploration of the surrounding
Sonoran Desert. Throughout his youth and early adulthood, he and his siblings freely explored the mountains and
arroyos
Arroyo often refers to:

Career
After completing his doctoral studies, Rasmussen was employed for one year as a visiting professor at
Rice University and then worked as an assistant professor for the
University of California, Los Angeles until 1991. That year he joined the Department of Anthropology in the Arts & Sciences at
Washington University in St. Louis (WUSTL), and ten years later achieved tenure as a full professor. Courses he taught at WUSTL included the history of physical anthropology and human

primate biology,
evolution, functional

paleobiology and
phylogeny. He also co-taught a course on human evolution as represented in film and culture together with a
cultural anthropologist and taught Environmental Studies starting in 1993. Rasmussen was the director of the graduate program and was a member of the Graduate Council in Arts & Sciences, both from 1993–1996 and 2004–2006, and was part of the university's
Fulbright Committee starting in 1999.

Throughout his career, he traveled both locally and internationally for his paleontological and archeological research. In the western United States, he visited California, Wyoming, Utah, Arizona, and New Mexico. He spent several summers with his colleague, Glenn Conroy, in the
Uintah Basin of Utah searching for the fossils of early mammals. Other fossil collecting trips included locations such as Egypt, Kenya, Libya, Ethiopia, Namibia, South Africa, Madagascar, Ecuador, and Colombia. His studies of

ns. In addition to his studies of fossil mammals, Rasmussen studied
ornithology, reporting on bird populations in Ethiopia and
sea eagle populations in the
Solomon Islands. He studied primates and birds in the
Neotropics, and in Costa Rica and Brazil, he studied the behavior of monkeys,
woolly opossums, and birds.

In 1996, he described a new genus and species of fossil primate, ''
Chipetaia lamporea'', an early
tarsiiform primate from
Middle Eocene found in present-day Utah. He also coauthored descriptions of the fossil primate genus ''
Aframonius'' and the family
Plesiopithecidae.
He wrote over 85 research articles during his career and was a doctoral advisor to nine graduate students at WUSTL.
Honors
Rasmussen is commemorated in the name of the fossil mammal ''
Widanelfarasia rasmusseni'', named in 2000 in recognition of his contributions to Egyptian paleontology.
During his tenure at WUSTL, he was acknowledged with the Excellence in Mentoring award twice by the Graduate Student Senate of College of Arts and Sciences. He also received the Outstanding Teaching Award and a
Mortar Board Teaching Award from the student body.
Following his death in 2014, Field Projects International created a scholarship in his honor, allowing a student from a

American Association of Physical Anthropologists on March 27, 2015.
Personal life
Rasmussen died in his home in Edwardsville, Illinois, at the age of 56 on August 7, 2014. He was survived by his parents and three siblings, Jan, Lora, and Brian Rasmussen.
