> TIL that "Bethe" is spelled "Bethe", and not "Beta". I can't remember seeing the name written down before, mostly heard it in audiobooks about Feynman's life.
Yes, it's pronounced "Bethe"... and the potential for a pun here led to the famous [Alpher-Bethe-Gamow](https://en.wikipedia.org/wiki/Alpher%E2%80%93Bethe%E2%80%93Gamow_paper) paper in which Gamow and his student Alpher showed that the Big Bang would create hydrogen and helium in the amounts we actually see! Bethe was roped in as a coauthor just for a joke.
Gamow later wrote:
> The results of these calculations were first announced in a letter to _The Physical Review_, April 1, 1948. This was signed Alpher, Bethe, and Gamow, and is often referred to as the 'alphabetical article.' It seemed unfair to the Greek alphabet to have the article signed by Alpher and Gamow only, and so the name of Dr. Hans A. Bethe (in absentia) was inserted in preparing the manuscript for print. Dr. Bethe, who received a copy of the manuscript, did not object, and, as a matter of fact, was quite helpful in subsequent discussions. There was, however, a rumor that later, when the alpha, beta, gamma theory went temporarily on the rocks, Dr. Bethe seriously considered changing his name to Zacharias.

C. Herman (who stubbornly refuses to change his name to Delter.)
