Weber Sr.'s involvement in public life immersed his home in both politics and academia, as his salon welcomed scholars and public figures like philosopher Wilhelm Dilthey and jurist Levin Goldschmidt.[26] The young Weber and his brother Alfred, who also became a sociologist and economist, passed their formative years in this intellectual atmosphere. For Christmas in 1877, a thirteen-year-old Max Weber gifted his parents two historical essays, entitled "About the Course of German history, with Special Reference to the Positions of the Emperor and the Pope", and "About the Roman Imperial Period from Constantine to the Migration Period".[27]
