The Johns Hopkins University opened in 1876.
The university has nine academic divisions and campuses throughout the Baltimore-Washington area. The Krieger School of Arts and Sciences, the Whiting School of Engineering, the School of Education and the Carey Business School are based at the Homewood campus in northern Baltimore. The schools of Medicine, Public Health, and Nursing share a campus in east Baltimore with The Johns Hopkins Hospital. The Peabody Institute, a leading professional school of music, is located on Mount Vernon Place in downtown Baltimore. The Paul H. Nitze School of Advanced International Studies is located in Washington's Dupont Circle area.
The Applied Physics Laboratory is a division of the university co-equal to the nine schools, but with a non-academic, research-based mission. APL, located between Baltimore and Washington, supports national security and also pursues space science, exploration of the Solar System and other civilian research and development.
Johns Hopkins also has a campus near Rockville in Montgomery County, Md., and has academic facilities in Nanjing, China, and in Bologna, Italy. It maintains a network of continuing education facilities throughout the Baltimore-Washington region, including centers in downtown Baltimore, in downtown Washington and in Columbia.
When considered in partnership with its sister institution, the Johns Hopkins Hospital and Health System, the university is Maryland's largest employer and contributes more than $10 billion a year to the state's economy.
