BTL 1961 - Dates in American Telephone Technology

paul-f@verizon.net (Paul F) — Wed, 26 Aug 2026 15:39:53 -0700

148 pages. By Dean Hanscom, Historian, BTL. Covers topics from prehistory through the mid-1950s. From the author's introduction:

This book lists important facts and dates for ready reference. It does not
elaborate and references are given only as sources for the dates indicated: other
and more detailed references may exist. With exceptions, 1956 is the closing date:
later advances must in general be covered in later editions.
The references are (with only a few exceptions) to published articles and books.
All such publications are in Bell Laboratories Library, Historical Collection, or
files. References to original laboratory notebooks and files are not given. Different
authors sometimes quote different dates for the same event; I have tried to establish
facts or a weight of evidence from published sources, but in some cases there
are unresolved differences. In a book of this scope, some errors are inevitable.
