?I will describe my formative years in England and my career in the United States, starting in 1964 at the University of Rochester, NY, and, since 1967, at Goddard.?? I will summarize our present understanding of how solar flares work, derived partly from observations made with more-and-more advanced X-ray and gamma-ray spectrometers, culminating with the Ramaty High Energy Solar Spectroscopic Imager (RHESSI).? Finally, I will review possible advances in instrumentation that could lead to major breakthroughs in the future.
