Leconte Hall

Built 1924. This was the site of the world's first atom smasher, built in 1931 by Ernest O. Lawrence, Berkeley's first Nobel laureate. With eight Nobel Prizes in physics held by UC Berkeley faculty and four more awarded to Berkeley alumni, LeConte Hall (designed by John Galen Howard) has been home to an impressive array of Nobel-caliber work. The building was named in honor of brothers John and Joseph LeConte, professors of physics and geology who came to Berkeley in 1866 following a stint running the Confederate powder works during the Civil War. John was university president from 1877-81.
