Abstract: The Hat Creek 85-foot telescope produced the first complete surveys of HI in the Northern sky–superseded only recently–and initiated measurements of the interstellar magnetic field using Zeeman splitting of the HI line in emission. These endeavors required state-of-the-art electronics and spectrometers. Here I review the role of the Berkeley Radio Astronomy Laboratory and its 85-foot telescope in their initiative roles for these three areas of science and technology and trace their evolution to the present. The present emphasizes the great single dishes of our times, the Green Bank Telescope (GBT) for Zeeman splitting and Arecibo for HI mapping; Fourier-transform spectrometers using FPGA technology; and sustaining the future with the synergy of research and education.
