We didn't have diodes in 1924. My generator didn't need diodes.
"The-Life-of-Me-an-autobiography"
Johnson, Clarence Edgar
This man was very fond of Diocles, a victor in the Olympic games, and when he left his country from a disgust at an improper passion which his mother Alithoe had entertained for him, and settled at Thebes, Philolaus followed him, where they both died, and where they still show their tombs placed in view of each other, but so disposed, that one of them looks towards Corinth, the other does not; the reason they give for this is, that diodes, from his detestation of his mother's passion, would have his tomb so placed that no one could see Corinth from it; but Philolaus chose that it might be seen from his: and this was the cause of their living at Thebes.
"Politics A Treatise on Government"
Aristotle
Three green diodes flashed, then two yellow ones, after which a white light came on and I heard a continuous hum, a dial tone.
