Massachusetts Institute of Technology holds its first classes.

Known originally as Boston Tech, it is founded by William Ware and begins as informal architecture classes in the Boston offices of Ware and Henry Van Brun in 1863. The first formal classes are held in rented rooms on Rowe Place and in the Mercantile Building at 16 Summer Street on February 20, 1865. The first four-year architectural school in the U.S., its first class of 15 students includes Louis Sullivan. William Barton Rogers is the first president. The school moves to a new building (first) on Boylston Street in 1866,* and by 1907 is located in 10 buildings and laboratories scattered throughout the Back Bay. It moves to a new campus in Cambridge in 1916.*
