REMARKS ON THE OCCASION OF RECEIVING THE 1980 ISMAR AWARD

In 1948, in the Institute of Hans Kopfermann in Gottingen, where I had just completed my experimental diplom-arbeit under Peter Brix, it was well known that I was supporting myself and my studies by the repair and barter of pre-war radios. So when Hubert Kruger, then one of Kopfermanns assistants, wanted to launch a search for rf spectra in solids, I was a natural choice and was signed on as his doctoral student. Prompted by the work of Pound (1) on <100 KHz quadrupole splittings in the NMR lines of single ionic crystals, Kruger suggested to me to choose a suitable compound, grow a single crystal as large as a child's head and build a superregenerative spectrometer (see Figure 1) as described by Roberts (2) and begin a search for the zero magnetic-
