"Photo shows Dr. Luis Alvarez, Nobel Laureate in the University of California Lawrence Radiation Laboratory, Berkeley, with some of the liquid hydrogen bubble chambers he developed, starting in 1953. In his hand he holds the primitive 2 inch glass chamber, with which he first explored the liquid hydrogen bubble chamber technology. Not visible are the subsequent 4 inch and 10 inch chambers. The 15 inch chamber is just below the 2 inch. The optical glass for the 72 inch chamber, which went into operation in 1959 and is the prototype of the large liquid hydrogen bubble chambers, is in the foreground. This chamber, remodled at Berkeley as an 82 inch instrument, is now in use at the Stanford Linear Accelerator Center.
"The photograph was taken shortly after Alvarez was awarded the 1968 Nobel Prize in physics for decisive contributions to elementary particle physics, in particular the discovery of a large number of resonance states made possible through development of the technique of using hydrogen bubble chamber and data analysis.
"Professor Alvarez's work was financed by the U. S. Atomic Energy Commission, which supports the basic research program of the Lawrence Radiation Laboratory."
