WORLD Bank president James Wolfensohn on Thursday hailed former Tanzanian leader Julius Nyerere as a founder of modern Africa and recalled his “high ideals, moral integrity and personal modesty.” Nyerere, who guided his country to independence from Britain in 1961 and then served as its president from 1964 to 1985, died in London Thursday at age 77.”While world economists were debating the importance of capital output ratios, President Nyerere was saying that nothing is more important for people than being able to read and write and have access to clean water,” Wolfensohn said in Washington.
