the Arizona Cactus Garden, the Stanford University Arboretum, Green Library and the Dish. Frank Lloyd Wright's 1937 Hanna–Honeycomb House and the 1919 Lou Henry Hoover House are both listed on the National Register of Historic Places. White Memorial Fountain (also known as "The Claw") between the Stanford Bookstore and the Old Union is a popular place to meet and to engage in the Stanford custom of "fountain hopping"; it was installed in 1964 and designed by Aristides Demetrios after a national competition as a memorial for two brothers in the class of 1949, William N. White and John B. White II, one of whom died before graduating and one shortly after in 1952. Administration and organization Stanford is a private, non-profit university administered as a corporate trust governed by a privately appointed board of trustees with a maximum membership of 38. Trustees serve five-year terms (not more than two consecutive terms) and meet five times annually. A new trustee is chosen by the current trustees by ballot. The Stanford trustees also oversee the Stanford Research Park, the Stanford Shopping Center, the Cantor Center for Visual Arts, Stanford University Medical Center, and many associated medical facilities (including the Lucile Packard Children's Hospital). The board appoints a president to serve as the chief executive officer of the university, to prescribe the duties of professors and course of study, to manage financial and business affairs, and to appoint nine vice presidents. The 11th and current president of Stanford University is Marc Trevor Tessier-Lavigne, a Canadian-born neuroscientist. The provost is the chief academic and budget officer, to whom the deans of each of the seven schools report. Persis Drell became the 13th provost in February 2017. As of 2018, the university was organized into seven academic schools. The schools of Humanities and Sciences (27 departments), Engineering (nine departments), and Earth, Energy & Environmental Sciences (four departments) have both graduate and undergraduate programs while the Schools of Law, Medicine, Education, and Business, have graduate programs only. A new School of Sustainability will supersede the School of Earth, Energy, & Environmental Sciences in September 2022. The powers and authority of the faculty are vested in the Academic Council, which is made up of tenure and non-tenure line faculty, research faculty, senior fellows in some policy centers and institutes, the president of the university, and some other academic administrators. But most matters are handled by the Faculty
