His face is on a dollar bill. People still learn from his ideas today.

Arthur Lewis was a famous thinker. He studied how money and work help countries grow.

He was born in Saint Lucia. As a boy, he was a very gifted student. He wanted to be an engineer. But, white firms would not hire a black engineer. So, he chose to study business instead. He won a scholarship to study in London. He was the first black person to go to that school. Later, he became a teacher in Britain. He was also the first black lecturer there.

Lewis had a big idea called the "dual-sector model." He said poor countries have two parts. One part is for farming. The other part is for modern industry. He showed how workers could move from farms to factories. This move helps a country build more wealth.

He helped many leaders in Africa and the Caribbean. He even helped Ghana make its first big plan. In 1979, he won the Nobel Prize in Economics. This is a very big honor. His face is on a 100-dollar bill in the East Caribbean.

Sir W. Arthur Lewis was a very important thinker. He was an economist who studied how countries grow. He is famous for his ideas about money and work. Lewis was also the only black person to win the Nobel Memorial Prize in Economic Sciences. This is a huge honor in the world of science. His work helped many new nations find their way.

Lewis had a special idea called the "dual-sector model." He said a poor country has two main parts. The first part is the traditional sector. This sector is mostly about farming and simple work. The second part is the modern capitalist sector. This sector is about factories and new industry. He showed how workers move from farms to factories. This move helps a country build more wealth and grow.

Arthur Lewis was born in Saint Lucia in 1915. His father, George Ferdinand, died when Arthur was only seven. His mother, Ida Lewis, raised five sons alone. Arthur was a very smart student in school. He wanted to be an engineer when he was young. However, white firms would not hire a black engineer. So, he decided to study business and law instead.

He won a scholarship to study in London. He was the first black person at the London School of Economics. He studied many subjects like accounting and statistics. Later, he became a teacher in Britain. He was also the first black lecturer there. In 1948, he became a full professor at Manchester. He later taught at Princeton University in the United States. He held the title of James Madison Professor of Political Economy.

Lewis helped many leaders in Africa and the Caribbean. He was an advisor for countries like Ghana and Nigeria. He helped Ghana make its first Five-Year Development Plan. In 1963, the British government gave him a knighthood. He also helped start the Caribbean Development Bank. In 1979, he won the Nobel Prize. Today, his face is on a 100-dollar bill in the East Caribbean.

Sir William Arthur Lewis was a pioneering economist from Saint Lucia. He studied how nations develop and grow their wealth. Lewis is most famous for his work in development economics. This field looks at how poor countries can become modern ones. He was the first black person to win the Nobel Memorial Prize in Economic Sciences. This happened in 1979 when he shared the award with Theodore Schultz. His research focused on the specific problems of developing countries.

Lewis developed a famous idea called the "dual-sector model." He called this the "Lewis model" in a 1954 paper. He described a poor country as having two distinct parts. The first is the traditional or subsistence sector. This sector is largely agricultural and relies on informal social norms. The second is the modern capitalist sector. This sector focuses on industrial growth and factory production. The model explains how these two parts interact to create change.

In the Lewis model, the traditional sector has a surplus of labor. This means there are more workers than there are jobs in farming. Because there is so much labor, the capitalist sector can grow easily. It can hire these extra workers without needing to raise wages immediately. This process allows capitalists to earn higher returns on their money. They then reinvest these profits back into their businesses. This reinvestment leads to more capital accumulation and more jobs. Eventually, the extra labor is absorbed into the modern sector. This transition point is known as the Lewisian turning point. At this stage, the balance of power shifts toward the workers.

Lewis's life was marked by many significant achievements and obstacles. He was born in Castries, Saint Lucia, in 1915. His father died when Arthur was only seven years old. His mother, Ida Lewis, raised five sons by herself. Arthur was a very gifted student and finished school at age 14. He originally wanted to be an engineer. However, he found that white firms would not employ a black engineer. He decided to study business and law instead. In 1932, he earned a scholarship to the London School of Economics. He was the first black individual accepted there. He later became the first black faculty member at that school.

His career took him to many important academic positions. In 1947, he became a lecturer at the Victoria University of Manchester. He was Britain's first black lecturer and became a full professor in 1948. Later, he moved to the United States to teach at Princeton University. He was the first black instructor to receive a full professorship there. He held the title of James Madison Professor of Political Economy. He also served as the Chancellor of the University of Guyana from 1966 to 1973. Lewis was a deeply respected figure in the global academic community.

Lewis used his expertise to help many new nations. As former colonies gained independence, they needed economic guidance. He served as an advisor to Nigeria, Ghana, Jamaica, and Barbados. In 1957, he was the first economic advisor to Ghana. He helped create their first Five-Year Development Plan for 1959 to 1963. He also helped establish the Caribbean Development Bank. In 1970, he became its very first president. His work helped shape the economies of the Caribbean and Africa.

His writings explored many different social and political ideas. In his 1939 book, he wrote about the labor movement in the Caribbean. He is now seen as an early supporter of reparations for colonial wrongs. In 1965, he wrote about politics in West Africa. He argued that the "winner-takes-all" political model might not work there. He suggested that power-sharing through coalition governments would be better. This was because many African states are divided by linguistic and tribal lines. Lewis believed institutional design could help maintain democracy in these regions.

Today, the legacy of Arthur Lewis remains very strong. His face appears on the East Caribbean 100-dollar bill. Many schools and buildings are named in his honor. The Sir Arthur Lewis Community College is located in Saint Lucia. The University of Manchester holds annual lectures in his name. His personal papers are kept at Princeton University for researchers. He passed away in 1991 in Barbados. His ideas continue to help scholars understand economic development today.
