Birthday William Holabird!! This American architect was from New York, born in 1854. Holabird studied at the United States Military Academy, West Point, for a time then moved to Chicago to begin his career as an architect. He helped establish the architectural style known as the “Chicago School”. The Marquette Building in Chicago features Chicago windows or “sash” windows where a large window is flanked by narrower windows on either side that open to let in air. He was a pioneer in creating the skyscraper as well.
