According to TFA, the name was coined by Andy Pavlo, who did his undergrad in New York, Doctorate in Rhode Island, and now teaches in Pittsburgh. I see no indication that he is German.
Andy Pavlo, ask anybody who knows him, is a very interesting character. I’m not sure if he really coined the name, or ist just a joke, as the one about his daughter (which I do both find funny at all). The database world (in which I was, is very interesting!) ;)
