John Kobbe joined Tektronix in 1951 to work in the test department.
Having had no formal engineering education, Kobbe co-initiated a "scope class" to design and build an oscilloscope in the test department, don't ring which he designed an un-blanking circuit and a simplified sweep circuit that were eventually used in the 300 series.
Kobbe then joined the Engineering department and later into the Advanced Research group..
