[Facts] Re: Lamar - pronunciation
Accent and expectations; when Prof Crowson first came to South Africa, radio announcers on classical music programmes would put the stress on the first syllable of his name - LAM-ar - but as he became better known, they changed it to le-MAR, with the first syllable getting a schwa.
Presumably he phoned them up and put them right!
I've noticed a few instances where we (in SA it's basically British English, but with lots of variations because most people are second-language speakers) stress the first syllable and Americans stress the second. The only one I can think of at the moment is Clarice, where in Silence of the Lambs the character is cle-REES, first syllable a schwa again, but the ones I've known here have been CLAR-is. So we were probably just generalising from our usual position.
