From 1942, when he began his doctoral studies, to the present time, Bob Beyer has been a leading voice in the discovery and discernment of acoustical phenomena, the development of educational programs to support students in acoustics, and the dissemination of information regarding acoustics. This introductory presentation will summarize the ‘‘parameter space’’ over which Bob has modestly but impressively held sway. It will include the fields of acoustics to which he contributed, his career as teacher–scholar at Brown University, his activities with the Acoustical Society of America, the American Institute of Physics, and other professional societies and organizations, and his many activities to aid in the internationalization of science, in general, and acoustics, in particular.
