   Harvard University is on the both sides of the Charles River. The oldest institution

of higher learning in the United States was founded in 1636. In 1638 it was named for John

Harvard, its first founder. During the 1640s the college was enlarged although it was short

of money. Meant to be an institution for the education of Puritan ministers (清教牧师),

it grew to be an institution of general education (普通教育), and new and more subjects and

policies (政策) were introduced. In the 18th century, particularly under John Leverett

(1708-24) the number of the students and campus equipment increased while the religious (宗

教的) color decreased. In its early years, the college was largely supported by the English

colony and the New England community as a whole, but support soon came in the form of gifts,

and in 1823 the state money was received for the last time. Under Charles W. Eliot, the

college became a great modern university. Its basic courses improved and enlarged, the

graduate school was set up for those who finished their four-year undergraduate study, and

the law and medical schools were reorganized. Eliot is also famous for his introduction

of the elective system at Harvard. Besides Harvard College, the university includes schools

of divinity (1816), law (1817), arts and science (1872), education (1920), engineering (1935),

reorganization of Lawrence Science School of l847, public administration (1935). Harvard also

has schools of business administration (1908), medical (1782), public health (1922), and dental

health (1941). Radckiffe college for women is connected with Harvard; its students are

taught by Harvard professors and receive diplomas given by Harvard. The university 1ibrary,

among the nation's finest, houses over 8 million volumes and the Fog Museum of Art is one

of the finest university museums in the world. Harvard is closely connected with a large

number of research institutions as well.
