Henry Hobson Richardson was an American architect born in 1838 in Louisiana. He studied in New Orleans and Paris and is considered the first American architect for breaking from European traditions. He developed the Richardsonian Romanesque style characterized by stone walls, arched windows, and dynamic interior spaces. His most famous work was Trinity Church in Boston constructed from 1872-1877, which featured a clay roof, rough stone, heavy arches, and a massive tower. Geometry played an important role in the symmetrical and Victorian design of the church, ensuring its structural integrity and longevity.
