The Society for the Prevention of Calling Sleeping Car Porters “George” was a lighthearted association with a useful, if incidental, cause. Most railway porters were black, and many passengers called them all George, following the racist custom of naming slaves after their masters. (George Pullman ran the company that made the cars, so the porters were regarded as his servants.)
Strangely, the prevention society was founded not by the black porters, but by white railway employees who were actually named George. Apparently they were either annoyed by the tradition or thought that such a society would be a good joke.
People did think it was funny, or at least inoffensive. At its peak, the society had 31,000 members, including King George V of the United Kingdom, Babe Ruth (whose given name was George), and French politician Georges Clemenceau.
