Bigg (1939–1990) was a Canadian marine biologist who is recognized as the founder of modern research on killer whales.
With his colleagues, he developed new techniques for studying killer whales and conducted the first population census of the animals.
Bigg's work in wildlife photo-identification enabled the longitudinal study of individual killer whales, their travel patterns, and their social relationships in the wild, and revolutionized the study of cetaceans.
