William Dizer, a former president of DuPont Japan Ltd. and former head of the American Chamber of Commerce in Japan, died July 12 in Hawaii. He was 79.

Born in the United States, Dizer served as a Japanese-language translator for the U.S. Army during World War II and later joined the staff of Gen. Douglas MacArthur in connection with the formation and administration of the Japanese government after the war.

When he retired and left Japan in 1990, Dizer was decorated by the Japanese government for his services during his career in Japan, which spanned nearly four decades.

His funeral service will be held on Maui. Donations in his memory may be made to the Alzheimer's Association of Maui and the Maui Memorial Medical Center Foundation.
