My personal favorite is Antoine de Saint-Exupery’s dedication on The Little Prince. What are your favorites?
“To Leon Werth
I ask children to forgive me for dedicating this book to a grown-up. I have a serious excuse; this grown-up is the best friend I have in the world. I have another excuse: this grown-up can understand everything, even books for children. I have a third excuse: he lives in France where he is hungry and cold. He needs to be comforted. If all these excuses are not enough, then I want to dedicate this book to the child whom this grown-up once was. All grown-ups were children first. (But few of them remember it.) So I correct my dedication:
To Leon Werth When he was a little boy”
This technically isn’t a dedication, but the first line of the first chapter of the textbook Statistical Mechanics by David L. Goodstein. Does it count?
“Ludwig Boltzmann, who spent much of his life studying statistical mechanics, died in 1906, by his own hand. Paul Ehrenfest, carrying on the work, died similarly in 1933. Now it is our turn to study statistical mechanics.”
I think you missed the bit about Ehrenfest also killing his children in a murder-suicide? But yes, that page hangs on my pinboard
