Hein Hvatum was born in Norway and educated in engineering in Sweden. He came to Green Bank in 1958 as one of our many early research scientists who visited for observing projects. He was hired as staff in 1961 and within the year had become the head of electronics. Hvatum later moved to the Charlottesville, Virginia offices where he headed up development of the 36-foot millimeter-wave telescope on Kitt Peak in Arizona. He served as the NRAO Acting Director in 1984 between Mort Roberts and Paul Vanden Bout. Hvatum led the Very Long Baseline Array (VLBA) project before retiring in 1987. He frequently enjoyed the challenging 120-mile bicycle journey from Charlottesville to Green Bank.
