You are certainly correct that pronunciation of a persons name is his/her prerogative, within reason.
But that the person does not correct others from misprounouncing it does not prove that it is being pronounced as it should be. Robert Muller might not care, consider it frivolous, a forlorn hope.
I myself have an 11 letter long Polish name which has been invariably mispronounced by Americans, tho a telling difference is I am not well known as notable figures are.. to me a shoulder shrug.
It was mainly tv talking heads who mispronunced circa 2010's as Muller rhyming with duller, rather than his father grandfather et al and generally Germans with the name Muller, pronouncing It properly as Myooler.
That was the point of the thread, that the reason the E appears after the U in Muller, to 'force' the U to be pronounced as a long U.
The thread pertains as well to other pronunciations of umlauted A O U German words.

Sorry, discretion prevents me from writing your pseudonym! But cheers nonetheless!

Emrys: I think Coch in German is better explained as ch having a k sound, rather than ch since ch implies itch. I know what you are saying in the Germanic pronunciation, but English speakers likely won't.
A k sound with a slight exhalation of sorts.
