Sid Sackson (1920-2002) is considered by many one of the greatest game designers of all time. A civil engineer by training, he devoted his time, later in life, to playing, collecting, and designing games of all kinds. His financial game Acquire was among the first published in the famous 3M bookshelf game series, and it is still in publication. Within his game collection he had a very early version of the game Avalon Hill later published, Baseball Strategy. The earliest versions of this game were made by a different firm. Avalon Hill very likely purchased this rights to the game from that firm.
