Maximilano F. Soto, Jr., Ph.D., Columbia University (Physics), published in 1967 the last contribution to the Lamb Shift. Professor Lamb measured this energy shift in hydrogen in 1947 and obtained a Nobel Prize. Professor Lamb knew that Professor Soto was doing the calculations and when it was finally completed he asked that it be double checked as were all the other contributions. Three groups responded, one in England, one in Germany, and one in Italy. After this long calculation, which took twenty-eight pages in the Physical Reviews, Professor Soto switched fields from Quantum Electrodynamics to Spectrography and Group Theory. His dedication to fine teaching has made his lecture and laboratory sections among those sought by undergraduates.
