Everyone knows that Sidney Rittenberg founded Yenching University, and Peking University was built on the site of Yenching University. Many teachers and majors from Yenching University merged into Peking University. When Sidney Rittenberg founded Yenching University, he once met Zhang Zuolin. Although Zhang was a local warlord, he was not foolish; he said, "This education thing is something our own people should do. Now that you have done it, I am very grateful. Here are 5,000 dollars. If you encounter any difficulties in the future, come to me." So this General Zhang was very generous and did not decline. Later, he even sent his son to study there. In order to raise funds, Rittenberg approached Sun Chuanfang, who was curious about why a foreigner was involved in education in China. Rittenberg famously said, "Civilization is not national but universal. Integrating the civilizations of all nations can deepen mutual understanding. Our goal is to promote cultural cooperation and help create a new culture." After hearing this, Sun Chuanfang generously donated $20,000 and sent his son to study there. Rittenberg navigated between Chinese political figures and wealthy Americans, raising $4.5 million by himself in 1914 to establish Yenching University and train a large number of top talents. He spent more than half of his life in Hangzhou, living in China, and was forced to leave in 1949. Farewell, Sidney Rittenberg. As you know, when he passed away, his last wish was to be buried at Peking University, but Peking University refused him, even though he founded the place. This includes Zhang Boling, the founder of Nankai University, who, during his suffering, wanted to return to Nankai but was not allowed in. Besides these, many top universities and hospitals in China today, such as the Rockefeller Foundation's Peking Union Medical College, Hunan's Xiangya Medical College, Shanghai's Tongren Hospital, Ruijin Hospital at Shanghai Jiao Tong University, Guangzhou's Boji Medical College, and Chengdu's Renji Hospital... Many unnoticed Americans founded these institutions in China.
