Adam Smith was a great scientist who made extraordinary contributions in economics.
He was born in 1723 in Kirkcaldy, a small fishing town near
Edinburgh, Scotland. His father was a customs officer. He died before
his son was bom.
At the age of 28 Adam Smith became a Professor of Logics at the
University of Glasgow. It was his first academic appointment. Some time
later he became a tutor to a wealthy Scottish duke. Then he received a
grant of £300 a year. It was a very big sum, 10 times the average income
at that time.
With the financial security of his grant, Smith devoted 10 years to
writing his work which founded economic science. Its full title was An Inquiry into the Nature and Causes of the Wealth of Nations. It was published with great success in 1776.
Adam Smith made economics a science. This Scottish economist is often regarded as the founder of political economy too.
