Louis Sullivan is considered to be the creator of the modern skyscraper and the father of modernism. He was the mentor to Frank Lloyd Wright and an influential figure to the Chicago group of architects that came to be known as the Prairie School. Born in Boston in 1856, Sullivan studied architecture for a year at MIT before leaving for the École des Beaux-Arts. Sullivan’s most famous works were the National Farmers Bank of Owatonna, Merchants National Bank, and Peoples Federal Savings and Loan. In 1944, he won the AIA Gold Medal.
