Venerable House, formerly known as Ruddock House, was constructed in 1960 in honor of Albert Billings Ruddock, then the Chairman of the Caltech Board of Trustees. It was renamed in 2021 in honor of Grant Venerable ('32), the first black undergraduate student at Caltech, due to Ruddock's involvement with the Human Betterment Foundation, a eugenics organization. Approximately 160 Caltech undergraduates are members of the house and approximately 80 reside in the house. Members of the house are known as "Vens" and were formerly nicknamed "Rudds." During the week, student waiters serve family-style dinners in the dining room; some notable dinner traditions include the throwing of bread rolls and "floating" members who break dinner rules by pouring water on them. The hallways, referred to as "alleys" by undergraduates, are adorned with various murals including reproductions of M. C. Escher works, a Monopoly Board, Simpsons characters, and a two-story mural of an astronaut. This mural, called "The Spaceman," is based on a photograph of Ed White's spacewalk during Gemini 4. The painting was made completely by Phil Cormier ('79) in a day's worth of work. A few years later Rusty Schweickart Jr. (whose father walked in space on Apollo 9) was elected house president. Another Ven connected to the space program is Philip Engelauf ('78), who later became a flight director at Johnson Space Center. Other Vens include Bill Gross of idealab!, MIT's Peter Shor (1981) – applied mathematician best known for Shor's algorithm in quantum computation, and Nobel Prize recipients Eric Betzig (Chemistry 2014) and Michael Rosbash (Physiology/Medicine 2017).
