Long time collector, historian, and electrical engineer Lloyd Espenschied (1889-1986), lived through some very exciting years in wireless technology and his writings can still be viewed as important. The following are a few. Lloyd became a amateur radio operator in 1904 and during summer vacations worked for United Wireless Telegraph Company. He graduated in 1909 from the Pratt institute with a degree in applied electricity. He gained a job with the American affiliate of the Telefunken Wireless Telegraph Company. His job was to install the Telefunken quenched gap systems for the US Navy. He joined Bell Labe for AT&T in 1910 until he retired in 1954. This was just the beginning for Lloyd. I will provide a link with much more info at the end of this article.

The 6 scans above are from the original paper in this author,s paper collection that Lloyd wrote in 1950 about his employment with the Telefunken Company of America. Who asked for the history is not known but my source was collector Will Jensby. I should guess that these were his notes for an AWA presentation or some such use.

This Lloyd Espenschied 1952 article appeared in the TCA magazine in Vol. 16, #2, 2014 Issue. Thanks to Keith Thrower for the submission.

Lloyd wrote several articles regarding DeForest inventing the audion, this being the first from the AWA Old Timers Bulletin Vol. 4, #1, 1963, shown above.

Lloyd wrote a second article on the same subject as above before his death in 1986. It was a bit larger and appeared in the AWA Old Timers Bulletin vol. 31, #3, 1990.

An article by Lloyd called “An Early Chapter in Radio-Electronics” was featured in Vol. 31, #1, 1990 of the AWA Old Timers Bulletin. Rare picture of Tyne and McCandless together.
