Irenäus Eibl-Eibesfeldt
Austrian ethologist who founded human ethology as a science.
Irenäus Eibl-Eibesfeldt was an Austrian zoologist, evolutionary biologist, behavioral scientist, and ethologist who pioneered the field of human ethology. He applied the methods and perspectives typically used to study animal behavior to humans, most notably in his book *Human Ethology*. His career was deeply intertwined with that of Konrad Lorenz, Hans Hass, and Otto Koenig, with whom he studied both animal and human behavior. Eibl-Eibesfeldt made several foundational contributions to marine biology and ethology, including being the first to describe cleaning symbiosis in reef groupers, the tournament behavior of marine iguanas, and the schooling behavior of fish. He also detailed the behavior of the cleaner wrasse and its mimic, *Aspidontus taeniatus*, and described multiple subspecies of the marine iguana on the Galapagos Islands, as well as several species of tube eels in the Indian Ocean. His work led to the creation of the world’s largest film documentary series on human behavior across different cultures, the discovery of universal patterns in human biology and culture, and the establishment of a research station on the Galapagos Islands. He was a passionate advocate for nature conservation. Born in Vienna in 1928, he was descended from an ancient knightly family. His father was a botany professor and his mother an art historian. After his father died from a World War I injury in 1941, his school performance suffered. Drafted in 1944, he served as an air force assistant but continued his studies, earning a wartime high school diploma. He began studying natural sciences at the University of Vienna in May 1945, later earning his Ph.D. in 1949 with a study on the mating biology of the common toad. He worked with Otto Koenig from 1946 and joined Konrad Lorenz’s institute in 1949. He participated in the first Xarifa expeditions to the Caribbean and Galapagos in 1953–54, and a second UNESCO mission in 1957, which led to the founding of the Charles Darwin Research Station. He later held professorships at the University of Chicago and LMU Munich, where he became a full professor in 1970.

Lore & Background
Born in Vienna, Austria, Irenäus Eibl-Eibesfeldt was a descendant of the ancient Regensburg knightly family Eibl von Eibesfeldt. His father, a professor of botany, and his mother, a trained art historian, fostered his early interest in zoology; by age ten he was reading natural history magazines. After his father died from war-related complications in 1941, his school performance declined and he was placed in a boarding school. In January 1944, at age fifteen, he was drafted as an air force assistant following four weeks of training. He earned a wartime high school diploma and began studying natural sciences at the University of Vienna in May 1945. He studied under Ludwig von Bertalanffy and Wilhelm von Marinelli, meeting Otto Koenig through Marinelli’s group. From 1946 to 1949 he worked at the Biological Station Wilhelminenberg, then became a research associate with Konrad Lorenz in 1949. He earned his Ph.D. in 1949 with a study on the mating biology of the common toad. He later moved to the Max Planck Institute for Comparative Behavioral Research, working in Buldern and then Seewiesen. In 1953 and 1954, he joined Hans Hass’s first Xarifa Expeditions to the Caribbean and Galápagos, where he drafted a memorandum on island protection. In 1957, on behalf of UNESCO and the IUCN, he surveyed the Galápagos, leading to the founding of the Charles Darwin Research Station and protected areas. He served as scientific director of Hass’s second Xarifa expedition to the Indian Ocean in 1957–58. He qualified as a professor in zoology at LMU Munich in 1963 and became a full professor in 1970. He was the first to describe cleaning symbiosis in reef groupers, tournament behavior in marine iguanas, and schooling behavior in fish, as well as the cleaner wrasse and its mimic. On the Galápagos he described several subspecies of marine iguana, and in the Indian Ocean, several species of tube eels. After two decades in animal ethology, he turned to human behavior in the 1960s, creating the world’s largest cross-cultural film documentary series on human behavior and establishing human ethology as an independent science.
Reader's Guide
Eibl-Eibesfeldt's significance lies in his pioneering role in establishing human ethology as an independent branch of behavioral biology. By applying methods from animal ethology to humans, he demonstrated that many behaviors—such as facial expressions of emotion and greeting rituals—are universal and likely innate, challenging theories that attributed all social behavior solely to socialization. His cross-cultural film documentation, spanning forty years and multiple indigenous groups, created an unparalleled archive of human behavior. His work on animal behavior, including the discovery of cleaning symbiosis in reef fish and descriptions of marine iguana tournament behavior, also contributed foundational knowledge to ethology.
