I recently obtained a copy of A History of The General Radio Company, published in 1965 by Arthur E. Thiessen Board Chairman of General Radio. The management style and policies of GR as Tek employees later referred to it, were strikingly similar to those of Tektronix.
Furthermore, General Radio, who was a quality leader in instrumentation before Tektronix was born, was also started by an Oregon native named Melville Eastham. Eastham was born on June 26, 1885 in Oregon City, OR. He left school at an early age, but his main philanthropic interest was the Massachusetts Institute of Technology, and many GR employees hailed from MIT.
An interesting piece of history is related on pages 39 & 40. GR developed The Electron Oscillograph Type 535-A in 1931, that was made in two parts. The CRT was mounted separately on a stand, and the power supply in a separate cabinet, and was connected to it by a cable. Following the invention of the so-called linear sweep circuit by Professor Frederick Bedell of Cornell University, GR produced the first commercial linear sweep circuit, called the 506-A Bedell Sweep Circuit. It was housed in a separate cabinet, so that a complete oscilloscope consisted of three parts.
The rest of the story, and the development of the monolithic scopes 687-A, and the 770-A to follow, and their dissolution, is explained in the attached .pdf excerpt from the book.
