This paper is basically a history of the evolution of the astronomical X-ray telescope as designed and engineered at American Science and Engineering, Inc. To that end, certain telescope designs have been selected which represent milestones along the evolutionary path taken by X-ray astronomy during the past few years. The developmental mile-stones presented here have been selected largely on the basis of a steady improvement in resolution paralleled by rather dramatic increases in collecting area.
