Dear PIGs: Petr Cerny passed away peacefully at home on Saturday, April 7, at the age of 84 years. To the many PIGs who knew and appreciated Petr, I suggest that you raise a tipple of Famous Grouse, his favorite beverage by any measure, in tribute to a great man and his great career. Petr would surely give his wry sideways smile, squinty eyes, and nods of approval. David London Stubbman-Drace Presidential Professor, Norman R.
