标题： The Discovery of Millisecond Pulsars: Don Backer and the Response to the Unexpected

摘要： 自1982年底Don Backer及其合作者发现毫秒自转周期脉冲星（MSP）B1937+21以来，已经过去了四十多年。 这一全新类别的天体的发现彻底改变了脉冲星天文学，并为未来数十年的创新科学探索提供了灵感，这种影响一直持续到今天乃至更远的未来。 在此，我们根据档案资料、个人书信和几位参与者的亲身经历回顾了导致这一发现的一系列事件。 我们还将简要回顾MSP在过去40年中对物理学和天文学产生的巨大影响，通过突出与MSP相关的重大科学成果来说明这一点。 显示英文摘要

摘要： It has now been just over four decades since the first discovery of a millisecond spin period pulsar (MSP), B1937+21, by Don Backer and collaborators in late 1982. This finding of an entirely new class of astronomical object revolutionized pulsar astronomy and provided inspiration for novel scientific investigation for decades to come, continuing to the current day and beyond. Here we review the events leading to the discovery, based on archival material, personal correspondence, and first-hand accounts of several of the participants. We also briefly review the enormous impact that MSPs have had on physics and astronomy by highlighting major MSP-related science of the past 40 years.
