John Mihelich, Professor Emeritus of Physics, has passed away in Fort Collins, Colorado, on March 10. John was a long-time member of our faculty and our nuclear physics group, joining Notre Dame in 1954 from Brookhaven. While here, he gained a national reputation in gamma-ray spectroscopy, training in his lab many of the later leaders in the field. He and his wife, Jan, raised three children in South Bend, spending their free time in travel, camping, and classical music. John retired in 1989, and he and Jan eventually moved to Fort Collins.
