The publisher of Jacques-Yves Cousteau’s biography claims he has a 1941 letter that reveals an anti-Semitic side of the undersea explorer. Portions of the letter were reproduced in the daily France-Soir on Thursday. (Cousteau died two years ago at the age of 87.) The letter was written shortly after Cousteau was transferred to Marseilles to work with French naval intelligence against the Nazi occupation. In the letter Cousteau complained of having trouble finding proper housing for his family. He said “there will not be a decent apartment until all those ignoble k—s burdening us are kicked out.” In response to the letter, Cousteau’s widow, Francine, vigorously denied that her husband was anti-Semitic.
