About Arthur Lewis
Sir William Arthur Lewis (23 January 1915 – 15 June 1991) was a Saint Lucian economist and the James Madison Professor of Political Economy at Princeton University. Lewis remains the only black person to have won the Nobel Memorial Prize in Economic Sciences. W. Arthur Lewis was a pioneering development economist, especially famous for his “dual-sector model” of economic development. In his 1954 paper “Economic Development with Unlimited Supplies of Labour,” he described a poor country as having two sectors: a traditional (largely agricultural) sector with surplus labor, and a modern capitalist sector. Lewis showed how surplus labor could be transferred from the traditional sector into the capitalist sector, fueling industrial growth. After Lewis graduated in 1937 with first-class honours, LSE gave him a scholarship to read for a PhD in industrial economics, under the supervision of Arnold Plant. Lewis would become the first black faculty member at LSE: in 1938 he was given a teaching appointment, and in 1939 was made an Assistant Lecturer, continuing to work as a member of the LSE staff until 1948.
