Named in memory of Bernard G. Hooghoudt (1924–1995), key engineer for Dutch radio telescopes, having designed the Dwingeloo telescope (1956) and the Synthesis Radio Telescope at Westerbork (1970). As a private consulting engineer he designed and led the construction of some of the world’s larger telescopes, not only for radio wavelengths, but also for millimeter and optical wavelengths.
