Pen names

Geisel's most famous pen name is regularly pronounced / s uː s /, an anglicized pronunciation of his German name (the standard German pronunciation is German pronunciation:). He himself noted that it rhymed with "voice" (his own pronunciation being / s ɔɪ s /). Alexander Laing, one of his collaborators on the Dartmouth Jack-O-Lantern, wrote of it:

You're wrong as the deuce And you shouldn't rejoice If you're calling him Seuss. He pronounces it Soice (or Zoice)

Geisel switched to the anglicized pronunciation because it "evoked a figure advantageous for an author of children's books to be associated with— Mother Goose " and because most people used this pronunciation. He added the "Doctor (abbreviated Dr.)" to his pen name because his father had always wanted him to practice medicine.

For books that Geisel wrote and others illustrated, he used the pen name "Theo LeSieg", starting with I Wish That I Had Duck Feet published in 1965. "LeSieg" is "Geisel" spelled backward. Geisel also published one book under the name Rosetta Stone, 1975's Because a Little Bug Went Ka-Choo!!, a collaboration with Michael K. Frith. Frith and Geisel chose the name in honor of Geisel's second wife Audrey, whose maiden name was Stone.
