Max Weber
Max Weber was a German sociologist, philosopher, and political economist who is widely regarded as one of the founding figures of sociology. His work has had a profound influence on the development of modern social theory.

Key Concepts
- Rationalization: Weber's concept of rationalization refers to the increasing dominance of rationality and efficiency in all aspects of social life. He argued that modern societies are characterized by the rationalization of the economy, bureaucracy, law, and even religion.
- Protestant Ethic: Weber famously explored the relationship between Protestantism and the rise of capitalism in his book "The Protestant Ethic and the Spirit of Capitalism." He argued that the Calvinist ethic of hard work and frugality played a crucial role in the development of capitalism.
- Authority: Weber identified three types of legitimate authority: traditional authority, charismatic authority, and rational-legal authority. He believed that authority is essential for the functioning of society.
