It has been reported that on 18th August 1913, in a game of roulette at the Monte Carlo Casino, the ball fell on black 26 times in a row. This anecdote is often mentioned in the context of the gambler's fallacy (see the wiki).
I am looking for information about the roulette wheel in use in Monte Carlo in 1913
In particular: was it the "European" type with one zero or the "American" type with two zeros? I would also appreciate a description --- even better a photo or sketch --- of the pattern of the numbers and colors around the wheel. These patterns have changed over the years and I have no information about the one that would have been in use back in 1913 in Monte Carlo.
My uneducated guess is that it would be a "European" type. But I have not found a reliable source of information on the matter. I have gleaned a few bits and pieces: The "American" roulette was originally the "French" roulette (introduced into what is now the United States via the French-owned Louisiana territory), while the "European" roulette was originally the "German" roulette. At some point (presumably by the end of the nineteenth century), the European/German model (which offers a better deal to gamblers) had displaced the American/French model throughout Europe. This did not happen in the United States, where the American/French model remains the most prevalent to this day. Given my limited information I venture to guess that by 1913, the European/German roulette would have completely replaced the American/French roulette in Monte Carlo.
But Monte Carlo being an atypical semi-enclave bordering France, perhaps their roulette was also atypical of the time and place?
I opted to post this question under "History of Science and Mathematics," but that was a bit of a gamble and I welcome suggestions to move it if there is a better outlet! (moderators, feel free to move it if convenient)
