Karl Marx
Karl Marx, a German philosopher, is well-known for his political, economic, and philosophical concepts. He was an outspoken critic of the governmental system from 1836 to 1860. He is best known for penning The Communist Manifesto in 1846, which has been studied by generations of people all around the world. Marxism, as it is currently understood, was his view that the working class could unite and defeat the capitalist system to create a world without classes.
Jack London
Jack London, who was born into poverty, tried his hand at gold mining before embarking on his writing career. Because the majority of people had never read science fiction before, his writing style was innovative for the time. Many of his books, including The Call of the Wild (1903), White Fang (1906), and The Sea Wolf (1904), were big successes. His personal life was not without controversy, as he was an avowed socialist and member of the radical literary collective “The Crowd” in San Francisco.
