摘要

Donald V.Helmberger was an unparalleled observa-tional seismologist,and theoretician.His pioneering work in seismic waveform modeling,and the numerical methods he developed to simulate seismograms to study the structure of the Earth and the nature of earthquake sources have become techniques that are now commonplace.But,that wasn't always the case.He once confided in me that when he was first proposing the modeling of whole waveforms there were not many who believed him that it was possible,and was'laughed at.'I don't know if that later part is true or not,but perhaps it was his way of teaching a young scientist about humility,and to give him confidence that the current scientific struggle will succeed with tenacity and hard work.
