James H Knapton (? – d. 2024)
From Tekscope V.3 No.4 July 1971:
James H. Knapton started his career with Tektronix in November, 1967 with design of the horizontal amplifier and calibrator in the 647, Tek's first solid state lab scope.
After a period of working with pulse generators and time mark generators, he tackled the chore of developing a replacement for the 575 Curve Tracer.
Jim contributed many of the fine features found in the 576, and recently added the 176 Pulsed High-Current Fixture.
Jim received his BSEE in June of '48 from the University of California at Berkeley.
