Jonathan Adolf Wilhelm Zenneck (/ˈzɛnɛk/; German: [ˈjoːnatan ˈtsɛnɛk]; 15 April 1871 – 8 April 1959) was a German physicist and electrical engineer.
Zenneck improved the cathode-ray tube by adding a second deflection structure at right angles to the first, which allowed two-dimensional viewing of a waveform. This two-dimensional display is fundamental to the oscilloscope.
