Joseph Arthur de Gobineau
Joseph-Arthur, comte de Gobineau was a French author and diplomat. He was the first to formulate the racial Aryan master race theory in his infamous Essay on the Inequality of the Human Races.
He was an establishment snob who believed the upper classes were better than everybody else and he attributed this superiority to genetic traits. Gobineau's ideas were deeply influential with thinkers in Nazi Germany. Gobineau's ideas have been referred to as Gobinism, and the most well-known people influenced by these ideas were Houston Stewart Chamberlain, Alfred Rosenberg, and Adolf Hitler.
