. In 1945, Thompson purchased McConnell Island off Washington State, financed through the sale of his valuable stamp collection. In 1951, Thompson's efforts in the field of oceanography were rewarded when the University of Washington established a department of oceanography. Thompson was recognized as one of the world's leading oceanographers and one of the pioneers of our understanding of the chemistry of the sea. Late in his life he was promoted to professor emeritus. He died in Seattle, Washington, on August 10, 1961.
