Georg Simmel (March 1, 1858 – September 28, 1918) -
Georg Simmel, German Sociologist, while not received especially well in his own time, has seen much greater influence since his passing. His prescient work, The Metropolis and Mental Life, presented as a lecture in 1903, analyzed the effects of the city and technology on the mind of the individual. The nuance of the essay has kept it relevant, refusing to define city life as harmful, just different.
He was also a pioneering force in sociological thought on social structure and social networking. Simmel's other most well-known sociological and philosophical works are The Philosophy of Money, The Stranger, and The Web of Group Affiliation.
