What was discovered

In 1926, without knowing of each other, Mayer in Germany and Norton in the United States separately reached the same conclusion: any circuit of resistances with voltage and current sources can be replaced by a single equivalent current source in parallel with an equivalent resistance.

This is a clear case of simultaneous independent discovery: Mayer published in the German journal Telegraphen- und Fernsprech-Technik and Norton in an internal Bell Labs technical memo; English-language literature settled on Norton's name, though it is sometimes cited as the Mayer–Norton theorem.

What it led to

  • Standard simplification of electrical circuit analysis
  • Symmetric counterpart to Thévenin's theorem in electronics education
