Coe Signal Company

The Coe Signal Company was founded by Douglass Coe in 1903, and was primarily a experimental laboratory that conducted research on the commercial applications of radio waves. Within the emerging field of radio, the company pioneered its use in military applications. In 1912 the company had been less profitable than Coe had hoped, and he merged it with the Douglass Coe Wireless Telegraph Company, his company focused on consumer telecommunications. The company kept the Coe Signal name. After Coe's death in 1925, his wife Gwendolyn formed all of the businesses under his name into Coe, in which the assets from the company evolved into the Telecommunications Department within Coe.
