摘要

George O. Squier, the inventor of the Muzak system, was the inventor as well, in 1910, of telephone carrier multiplexing, the forerunner of microwave frequency multiplexing after World War II, and its current incarnation as optical wavelength multiplexing. Squier was a Major in the United States Army Signal Corps at the time, later becoming Major General and Chief Signal Officer. His invention was initially rejected by AT&T engineers as not being commercially viable. This view was not shared by others in the engineering community, including John Stone Stone, a distinguished independent telephone engineer. After prodding by Stone, AT&T officials began a reappraisal of the "wired wireless" system, as Squier chose to call it, and by 1914 development of a commercial system, was underway. By 1918, however, when the AT&T system went into service, AT&T was claiming that Squier's work had only been "suggestive" and that its system was based on inventions of its own engineers. We describe the sequence of events, beginning with Squier's invention, that led to the AT&T commercial rollout of carrier multiplexing. We also offer some possible reasons, based on archival documents, as to why AT&T downplayed Squier's invention.

Squier于1910年也是电话载波多路复用的发明者，它是第二次世界大战后微波频率多路复用的先驱，其当前的化身是光波长多路复用。斯奎尔当时是美国陆军信号兵团少校，后来成为少将和首席信号官。他的发明最初被AT＆T工程师拒绝，因为它不具有商业可行性。工程界的其他人，包括杰出的独立电话工程师约翰·斯通·斯通（John Stone Stone），都没有这种观点。在斯通的敦促下，AT＆T官员开始重新评估“有线无线”系统，Squier选择将其命名为“有线无线”系统，并在1914年开发了商用系统。但是，到1918年，当AT＆T系统投入使用时，AT＆T声称Squier的工作只是“建议”，其系统是基于其自己的工程师的发明。我们从Squier的发明开始描述事件的序列，这些事件导致了AT＆T载波复用技术的商业推广。基于存档文件，我们还提供了一些可能的原因，以说明AT＆T为何低估了Squier的发明。
