Not much is actually known about this strategy. We cannot even say clearly when and why this strategy began to be used in roulette. We only know that the system is named after the famous Enlightenment physicist and mathematician Jean le Rond d’Alembert. Specifically, after his important physical work, which is now known as d’Alembert’s principle.
In some sources, we read that d’Alembert himself used this strategy during the game and tried to beat the roulette wheel with it. However, this is probably just a myth. D’Alembert died 16 years before the first real game of roulette as a gambling game was supposed to take place.
The fact is that this system has been used in the gambling industry for many years and players are trying to use it to their advantage and get interesting winnings thanks to it.
