Stanford University, officially known as Leland Stanford Junior University, is a private research university located in Stanford, California. It was founded in 1891 by Leland Stanford, a railroad magnate and former California senator and governor, and his wife Jane Lathrop Stanford, in memory of their son, Leland Stanford Jr. Prior to 1920, all tuition fees were waived, but the death of Leland Stanford in 1893 and the devastating 1906 earthquake that damaged the campus led to severe financial difficulties. After World War II, Frederick Terman, the university’s provost, strongly supported alumni and faculty in developing local industries, which contributed to the rise of Silicon Valley. The main campus is located in the northwest part of Silicon Valley, near Palo Alto, between San Jose and San Francisco. The university consists of 3 academic schools and 4 professional schools. Graduate programs are not only academically prestigious but also a breeding ground for talent in California's Silicon Valley. Notable schools include the Graduate School of Education, the School of Engineering, the Law School, the School of Medicine, and the Graduate School of Business, which is considered one of the world’s dream schools. Stanford currently fields 36 competitive athletic teams, 19 intramural sports teams, and 37 club sports teams. Their athletic teams are officially named the "Stanford Cardinal," referring to the cardinal red color, not the bird. Stanford's biggest rival is the University of California, Berkeley, and the winner of the annual "Big Game" earns the right to hold the "Stanford Axe" trophy. Many tech companies such as Google, HP, Nike, Instagram, Snapchat, and Yahoo were founded by Stanford alumni. These companies generate over $2.7 trillion in annual revenue, making them equivalent to the 10th largest economy in the world. The university has produced 30 billionaire entrepreneurs, 17 astronauts, U.S. President Herbert Hoover, and golfer Tiger Woods, and is one of the top institutions for producing U.S. Congress members. Stanford is also home to 60 Nobel laureates who have either studied or worked at the university.
