I think the exact origin is unknown. SOme say it morphed from one white and one black flag waving to signal the end of the race and some say it was used in place of actual men in checkered shirts signifying the finish line.
I have never seen the difinitive answer.

bodyshop, been there. Best they have is 1904. I have sent the Milwaukee mile an e-mail asking them if they used the checkered flag for the first car race at the mile on September 11, 1903.
Black and white because ?? a relatively higher percentage of men (rather than women) are color blind?? Black and white checker versus a specific color to signal the end of a race?
Green at the start wouldn't be a problem, yellow out on the course shouldn't be a problem, but if not a "checkered" flag at the end, you might not know (if you're color blind) what the heck the guy is waving at the END of a race??
I don't think there will ever be a definitive answer to this frequently asked question. The best theory I know of came from a panel of experts more than 50 years ago determining that the checkered flag evolved out of bicycle racing in France in the 1860s, two decades before there was any such thing as an automobile. It has been suggested that it was introduced to this country by Alexander Pope who was legendary in the bicycle industry. It appears to have been used in automobile racing since the very beginning.
