East Campus has the complexes of Stern, Wilbur, and Gerhard Casper Quad and the standalone dormitories of Branner, Toyon, Mirrielees, and Crothers.[6] The founders, Leland and Jane Stanford, rejected the idea and decided that the recently built Hôtel Kursaal de la Maloja in Switzerland would be the model for the original men's dorm, Encina Hall, housing 300.[6] Encina Hall proved problematic as a dorm and now houses administrative offices and the Political Science department.Jane Stanford insisted that both men and women be admitted in the first class and so new plans were drawn up for a building using Ernest L. Ransome's reinforced concrete instead of sandstone and it was built in 97 days.[8] Stanford then paused its construction program and no new halls were built for several decades, though the Manzanita trailer park was set up in 1969 to provide temporary housing.In 2015 the new Ng House was opened and in 2016 the Manzanita Park complex was renamed Gerhard Casper Quad.Most graduate housing consists of apartment complexes such as Lyman, opened in 1997, Munger, Rains, and GSB (the last has priority for business students).A legacy issue with the pre-1978 construction is the widespread presence of exceptionally hazardous toxins in the building materials.As the old housing stock is demolished and rebuilt, these toxins at time are released through carelessness into toxic dust clouds.[24][25] Toyon Hall is an upperclassman dorm, designed by Bakewell and Brown and built in 1923 to house 150 men.[26] Toyon was the home of the Stanford Eating Clubs, a system of originally all-male organizations which served a social function as well as a food service plan.It was built in the late 1940s and represents an architectural departure from Stanford's usual theme of sandstone-colored, arcaded buildings with red tile roofs.[29] Florence Moore Hall, often abbreviated as FloMo, consists of seven different houses: Alondra, Cardenal, Faisan, Gavilan, Loro, Mirlo, and Paloma.[34] As a result of Stanford's Neighborhood System, Adams and Schiff have since become independent of each other and each house ~100 freshman and upperclass students in a non-themed environment.[35] The names of the suites honor former Stanford academic leaders and faculty members: Melville Best Anderson, the first head of the English department; James Owen Griffin, who was invited by President Jordan as one of the first faculty; Oliver Peebles Jenkins, first professor of Physiology and Zoology; and Charles David Marx, the first professor of Civil Engineering.Meals for the suites are served in four Dining Clubs: Avanti, Beefeater, Bollard and Middle Earth.These houses are Eucalipto (eucalyptus), Granada (pomegranate) and Adelfa (oleander) on the west side, and Naranja (orange) and Ujamaa (which consists of two buildings formerly named Olivo and Magnolia) on the east.Ujamaa (Swahili for extended family) is the home of the African American theme program and Adelfa has a writing focus.All of the row houses are owned by the university, except 550 Mayfield which was formerly home to fraternity members of Sigma Chi.
