In Fantasia, what is the name of the sorcerer?

In Fantasia, the sorcerer is named Yen Sid.

Yen Sid appears in “The Sorcerer’s Apprentice,” the 1940 Fantasia segment in which Mickey Mouse serves as his inexperienced apprentice. Before taking a break, Yen Sid casts spells and leaves his magical hat behind. Mickey puts it on a broom, giving the broom a life of its own, but loses control when the enchanted helper multiplies and floods the sorcerer’s cavern. Yen Sid eventually returns and reverses the spell.

The name “Yen Sid” is Disney spelled backward. The character was created for the film and is not named in Goethe’s original 1797 poem, “The Sorcerer’s Apprentice,” or in Paul Dukas’s orchestral adaptation. Yen Sid’s stern, imposing design contrasts with Mickey’s impulsive curiosity and makes the segment’s lesson about magical power especially clear.

A frequent mix-up is Chernabog, the huge demon from “Night on Bald Mountain,” another Fantasia segment. Leopold is not the sorcerer; Leopold Stokowski conducted the score. Yen Sid later appeared in Disney games and other media, including Kingdom Hearts and Fantasia: Music Evolved.
