Bleeker (1909-1971) was the author of:

The Sea Hunters: Indians of the Northwest Coast (New York: William Morrow, 1951). Illustrated by Althea Karr. Giving an overview of the cultural practices of the tribes in the Pacific Northwest, this book delves into the practice of the potlatch, how the natives of the coast had to create a civilization without access to decent clay or copper, and other unique qualities that belong to the tribes of the Pacific Northwest.
