(Dr. Seuss) Geisel’s pen name is regularly pronounced /ˈsjuːs/ SEWSS, an anglicized pronunciation inconsistent with his German surname. He himself noted that it rhymed with “voice” (his own pronunciation being /ˈsɔɪs/ SOYSS).
Alexander Liang wrote of him:
You’re wrong as the deuce
And you shouldn’t rejoice
If you’re calling him Seuss.
He pronounces it Soice (or Zoice)
