ABSTRACT
Most stabilized-image studies in the United States derive from the work of either L. A. Riggs or D. H. Fender (a student of R. W. Ditchburn in the U.K.). My long-time friendship with Derek Fender has been a source of much pleasure, but my scientific heritage is more directly connected to Riggs by the influence of his students, particularly Tom Cornsweet and Ulker Tulunay-Keesey. There was no formal collaboration, but even Riggs eventually served as a subject in one of my experiments. I had been interested in stabilized-image experiments ever since graduate school (when I wrote to ask Riggs about some data), but I had no opportunity to participate in the field until I moved to SRI in 1966.
