The Bergamo Brothers were comprised of Luciano and Pietro Bergamo when they were twelve. It was also the name of their circus act, "The Amazing Bergamo Brothers and their Symphony of Smells."
Pietro Bergamo, and his identical twin brother, Luciano Bergamo, were born in Italy in the 1910's. He and his twin brother Luciano lived with their parents and had a mostly happy life, (even playing with their neighbor's daughter, until their twins' synesthesia prompted them to tell her that she was writing her name with the wrong color chalk, causing her to be upset) until the fascist dictator Benito Mussolini came to term in 1922.
Their parents sent them to the United States, hoping for the brothers to stay with relatives in Kansas, Missouri. While on the ship headed to America, the brothers entertained sailors with card tricks their father had taught them, leading them to discover their talent for magic.
After getting lost in the wrong part of Kansas, the two live on the streets until they sneak into a circus, and subsequently join said circus. After working several odd jobs at the circus, they manage to impress the ringmaster's daughter with their tricks, gaining their own act; The Amazing Bergamo Brothers and Their Symphony of Smells.
The mentioned "Symphony of Smells" appears to them after they start their act, sent by a mysterious donor, "The Golden Lady". One day, the donor, referred to as "The Golden Lady", supposedly takes Luciano out to dinner, yet he never returns.
From there, Pietro finds out that they were sold by the circus ringmaster to "The Golden Lady" for a large amount of money and he runs away, thus ending their act.
