Wireless Telegraphy and Telephony: An Outline for Electrical Engineers and Others

First published in 1921, this book was originally intended to supplement the knowledge of electrical engineers with limited experience of wireless telegraphy. Turner examines various branches of the technology’s development, focusing especially on the thermionic method of wireless, and compares telegraphy to telephony. This book will be of value to anyone with an interest in the history of science, telegraphy in particular.
