Richard Nickel was a prolific and passionate letter writer. Here are a few quotes:
"I am on earth in [Sullivan's] behalf, and I have only begun to fight."
"What is going on in Chicago?. . .Many smaller insignificant Adler and Sullivan buildings have gone, but now the Garrick?"
"Great architecture has only two natural enemies: water and stupid men." "Marvelous being in a work of art under rape. How often do you experience the bones, veins, skin of a work of art, even if it be in dissection?"
"What a fool I must be. Why am I horsing around, moving the stones from one warehouse to another, while everybody else is making a dandy living, have their own lives and apartments and houses, etc.? It's even a problem for me to buy a car." (reacting to a magazine's praise of the parking garage that replaced the Garrick) "They wreck one of [Sullivan's] masterpieces, and you conclude it is a tribute? Would you say that if someone wrecked St. Peter's Cathedral in Rome and erected a garage. . .that that was a tribute to St. Peter?"
