Charles Lutwidge Dodgson (a.k.a. Lewis Carroll, author of Alice’s Adventures in Wonderland) practiced memory techniques. His memory system has some similarities with the Major System but seems more complicated in its letter choices: 1. “b” and “c,” the first two consonants in the alphabet. 2. “d” from “duo,” “w” from “two.” 3. “t” from “tres,” the other may wait awhile.
