I came across the below article today that discusses the history of billiard balls, from wood, to ivory, to early plastics, and to the modern phenolics. It was quite interesting to me, especially in light of the recent Cyclop ball being a new option on the ball scene. I think the article was written in the mid 80's, and then whoever put it on the web updated it with further information in the past 5 years.
One interesting part near the end of the article was that the Rashig company invented the modern phenolic ball, and its head guy being Jewish fled Germany during the war and shared his knowledge with the competitor companies to keep him out of Germany.
