John Gates worked for Hickok and was associated with the clone oscilloscopes.  In 1960 he took a job with Tektronix and worked on the 82 dual-trace plug-in, the 81A plug-in, and the 581 and 585 oscilloscopes.  He designed the 82, 84, and 86 plug-ins as well as the vertical amplifier for the 545B.  I also worked in John Kobbe's Advanced Instrument Design group on future concepts.

In May of 1965 he was responsible for the first Sony/Tektronix development project, the design of the 323 mini-oscilloscope. This Summer/Fall 1968 TekTalk describes his contributions to Sony/Tek and the development of the 323 mini-oscilloscope. Click on the image to view the PDF.
