Karl von Frisch

Karl von Frisch (1886–1982) was an Austrian ethologist who investigated honeybee senses and communication. He shared the 1973 Nobel Prize in Physiology or Medicine for discoveries about animal behavior.

Nobel Prize in Physiology or Medicine: An annual international award recognizing discoveries in physiology or medicine. Frisch shared the 1973 prize with Konrad Lorenz and Nikolaas Tinbergen for discoveries about animal behavior.
Waggle dance: A honeybee movement pattern that communicates the direction and distance of a food source. Frisch demonstrated that the dance conveys navigational information to other bees.
Animal cognition: The mental capacities animals use to perceive, learn, remember, and solve problems. Frisch's tests of bee perception raised questions about what insects can know.
Animal communication: The transmission of signals between animals that influence behavior or convey information. The waggle dance became a landmark case in the study of animal signaling.
Konrad Lorenz: An Austrian zoologist who helped establish ethology as the study of animal behavior. Lorenz shared the 1973 Nobel Prize with Frisch and Tinbergen.
Honeybee communication: The exchange of information among honeybees through movement, chemicals, sound, and touch. Frisch's best-known research established that bee dances communicate food locations.
Classical conditioning: A learning process in which an association forms between a stimulus and a response. Frisch trained bees to associate visual cues with a sugar reward.
Animal behavior: The actions and responses of animals in relation to their environments and one another. Frisch's work helped make behavior experimentally tractable as a biological subject.
Nikolaas Tinbergen: A Dutch ethologist who developed experimental methods for studying animal behavior. Tinbergen shared the 1973 Nobel Prize with Frisch and Lorenz.
Honeybee vision: The visual abilities of honeybees, including color and pattern discrimination. Frisch tested bees' color vision and showed they can distinguish colors.
