Adam Smith was an influential Scottish economist born in 1723. He is known for his book The Wealth of Nations published in 1776 which discussed concepts like the division of labor and free market capitalism. The document discusses Smith's life and work, including his theory of work specialization which argued that breaking down jobs into smaller tasks and assigning them to specialized workers improves productivity. An example given is Smith's pin factory example which demonstrated how separating the 18 steps of pin production among 10 workers could dramatically increase output.
