The School of Law was founded in 1925 as a part of the then private, nonprofit University of Baltimore, with the first class of 38 students receiving their diplomas in 1928. Created initially to serve the working population of the Baltimore area with a part-time evening program, the school added a full-time day division in 1969.
In September 1970, the University of Baltimore School of Law merged with Eastern College and its Mount Vernon School of Law, which was founded in 1935. On January 1, 1975, the school became a public institution when the University of Baltimore joined the State of Maryland's system for public higher education.
After its grand opening on April 30, 2013, the new John and Frances Angelos Law Center will host classes for the student body beginning with the summer 2013 session. This 12-story facility, located on the northeast corner of the intersection of North Charles Street and West Mount Royal Avenue, houses all of the school's clinics, centers and classrooms, and affords students countless options for indoor and outdoor study spaces. Perhaps most notably, an effort is underway for the building to be designated Leadership in Energy and Environmental Design (LEED) platinum by the U.S. Green Building Council.
An alumni network of approximately 13,000 graduates includes many prominent figures, such as Peter Angelos, owner of the Baltimore Orioles; Maryland's first lady, Judge Catherine Curran O'Malley; Thomas Condon, largely considered to be the most powerful agent in professional football; and United States Congressman C.A. Dutch Ruppersberger III. Nearly a third of Maryland's sitting judges are UB School of Law graduates, and the number of University of Baltimore law alumni who serve among Maryland's 188 elected officials is second only to that of the University of Maryland, College Park.
