The successful design, construction, and operation of the Chandra X-Ray Observatory.

Concerns and suggestions for the future development of X-ray astronomy.

Abstract

I summarize the excitement of my role primarily in the early years of X-ray Astronomy. As a "second-generation" X-ray astronomer, I was privileged to participate in the enormous advance of the field, both technically and astrophysically, that occurred in the late 1960's and 1970's. The remainder of my career has concentrated on the design, construction, calibration, operation, and scientific maintenance of the "cathedral" that is the Chandra X-Ray Observatory. I contrast my early experiences with the current environment for the design and development of instrumentation, especially X-ray optics, which are absolutely essential for the development of the discipline. I express my concerns for the future of X-ray astronomy and offer specific suggestions that I hope will advance the discipline at a more effective and rapid pace.
