Theodore J. Walker

Theodore J. Walker was an American biologist, oceanographer, and author best known for his work on whales, especially the California gray whale. Reference sources describe him as a noted marine biologist who was born in Great Falls, Montana, on January 7, 1915, and died in Seattle, Washington, on February 28, 2003.

His academic path took him from Montana State University, where he earned a B.A. in 1938, to the University of Oklahoma for an M.S. in 1940, and then to the University of Wisconsin–Madison, where he completed his Ph.D. in 1947 after serving as a lieutenant in the U.S. Navy during World War II. Reports published after his death said he became widely respected as a leading authority on the California gray whale and helped spark broader public interest in whale watching on the West Coast.

For readers, Walker is closely associated with books such as Whale Primer: With Special Attention to the California Gray Whale and Red Salmon, Brown Bear: The Story of an Alaskan Lake. Late in life, he also volunteered at the Seattle Aquarium, where he shared his love of ocean life with children and visitors — a fitting extension of the same generous, explanatory spirit found in his writing.
