Suzuki, David Takayoshi (1936-) is a geneticist, broadcaster, and author known for his stand on environmental issues.

Suzuki was born in Vancouver, British Columbia. After the attack on Pearl Harbor in 1941, sentiments against Japanese ran high. Even though his parents were Canadian-born, when Suzuki was 6 years old, his family, along with hundreds of other Japanese-Canadian families, was interned in a camp in the Canadian interior.

He was awarded a scholarship to Amherst College in Massachusetts, from which he received a B.A. degree in biology in 1958. He earned a Ph.D. degree in zoology from the University of Chicago in 1961. That same year he was a summer fellow at the Rocky Mountain Biological Laboratory in Crested Butte, Colorado, and from 1961 to 1962 was a research associate at Oak Ridge National Laboratory in Oak Ridge, Tennessee.

In 1962, Suzuki became assistant professor of genetics at the University of Alberta in Edmonton. He joined the faculty of the University of British Columbia in Vancouver in 1963, where he was appointed professor of zoology in 1969, and is currently an associate of the Sustainable Development Research Institute there.

An interest in communications led him to agree to do three half-hour science television programs for the Canadian Broadcasting Corporation in 1969. He did several other science programs for television and radio, and in 1979 became host for a program on CBC called The Nature of Things, which became internationally syndicated.

In 1990, Suzuki and his wife, Tara Cullis, established the David Suzuki Foundation to research and publicize environmental issues.

He is the author of more than 30 books, including 15 geared toward children. He was elected an officer of the Order of Canada, a fellow of the Royal Society of Canada, and a fellow of the American Association for the Advancement of Science.
