Frankie Darro was born on Saturday, December 22, 1917 in Chicago, Illinois as Frank Johnson, Jr. His parents, Frank Johnson, Sr. and his wife Ada were known as The Flying Johnsons, a flying circus act with the Sells Floto Circus; it was a profession that his father attempted to train him in, and he cured Frankie's fear of heights by having him walk on a length of wire, and then gradually raised the height of it until his son had mastered the trick.
