In 1964, he became a full professor at the University of California, San Diego, coordinating activities at the Institute of Geophysics and Planetary Physics. In 1979, the Association for the Advancement of Medical Instrumentation (AAMI) awarded Holter with the AAMI Foundation Laufman-Greatbatch Prize for his contributions to medical technology.
Holter was the son and grandson, respectively, of Montana pioneers Norman B. Holter and Anton M. Holter. Anton M.
