This archival photograph, dated March 7, 1969, is on display at The Lawrence Hall of Science and is hung on the wall leading up to the BELLA lab in Berkeley Lab's Building 71. In the photo, seven Berkeley Lab Nobel laureates pose in front of E. O. Lawrence’s 37-inch cyclotron magnet. The laureates, from left to right, are: Owen Chamberlain, Edwin M. McMillan, Emilio G. Segrè, Melvin E. Calvin, Donald A. Glaser, Luis W. Alvarez, and Glenn T. Seaborg. Weighing 85 tons, the 37-inch cyclotron superseded the original 27-inch cyclotron and from 1932 to 1939 led to many discoveries, including creating radioisotopes and the first artificial element, technetium.
