Hilb's Day is a longstanding Illinois Tech tradition to celebrate the shortest day of the year. Ludwig K. Hilberseimer (1885–1967) was a German architect and urban planner best known for his ties to the Bauhaus and Mies van der Rohe. He was founder and chair of Illinois Tech’s Department of City and Regional Planning where he taught from 1938 until his passing in 1967. At Illinois Tech, he developed a universal, adaptable system, which planned for the darkest day of the year (“Hilb’s Day”) in order to produce environments with as much light as possible.

Every year this event is held “live” in the Carr Chapel, but this year it is going to be conducted virtually via ZOOM to allow all friends locally, nationally and internationally to toast Professor Hilberseimer on December 13!
