Smith Hempstone, who served as U.S. ambassador to Kenya from 1989 to 1993, died on Nov. 19 in Bethesda, Md., of complications of diabetes. As ambassador, Mr. Hempstone became an effective, aggressively undiplomatic critic of the country's president, Daniel arap Moi.

Mr. Hempstone and his wife, Kitty, participated in the activities of the Friends of Kenya, continuing their interest in the people and affairs of Kenya.

The Friends of Kenya board and its members express their condolences to Kitty, their daughter and grandson.
