A reader: “(Quoting me) ‘The correct pronunciation of Euler’s name can be deduced from the following tribute…’ Only a eejit would not know how to pronounce Oiler. I thought you would tell the hoi polloi how to pronounce Leonhard. Hard ‘d’ or soft? Lee-o or Ley-o?” [Me] Funny, no-one ever asked me that before. I have always heard, and said, “LAY-on-hart,” but I will take correction from any Swiss-German readers of The Corner. And btw I was always told that “the hoi polloi” is a pleonasm, as “hoi” means “the.” But I’ll take correction on that, too, since I know no Greek.
