Adam Smith (baptised 16 June 1723 – 17 July 1790 [OS: 5 June 1723 – 17 July 1790]) was a Scottish moral philosopher and a pioneer of political economy. One of the key figures of the Scottish Enlightenment, Smith is the author of The Theory of Moral Sentiments and An Inquiry into the Nature and Causes of the Wealth of Nations. The latter, usually abbreviated as The Wealth of Nations, is considered his magnum opus and the first modern work of economics. Adam Smith is widely cited as the father of modern economics.[1][2]

Smith studied moral philosophy at the University of Glasgow and Oxford University. After graduating he delivered a successful series of public lectures at Edinburgh, leading him to collaborate with David Hume during the Scottish Enlightenment. Smith obtained a professorship at Glasgow teaching moral philosophy, and during this time wrote and published The Theory of Moral Sentiments. In his later life he took a tutoring position which allowed him to travel throughout Europe where he met other intellectual leaders of his day. Smith returned home and spent the next ten years writing The Wealth of Nations, which was published in 1776. He died in 1790.

Adam Smith is known for his explanation of how rational self-interest and competition, operating in a social framework depending on adherence to moral obligations, can lead to economic prosperity and well-being. His invisible hand metaphor, which he used to describe this process, has gained widespread use in the discussion of free markets. Smith's work helped create the modern academic discipline of economics and provided one of the best-known rationales for free trade.
