Max Weber was a German sociologist born in 1864 in Erfurt, Germany. He is best known for his book The Protestant Ethic and the Spirit of Capitalism, which argued that Protestant beliefs, especially Calvinism, influenced the development of capitalism. Specifically, the Calvinist beliefs in predestination and dedicating oneself to their earthly calling encouraged hard work and abstaining from pleasures. This opened the possibility for the spirit of capitalism to take hold in Europe where work became an end in itself. This was one of the first analyses of how religion influences economic systems.
