Word Origin and History for cracker-jack

also crackerjack, "something excellent," 1895, U.S. colloquialism, apparently a fanciful construction. The caramel-coated popcorn-and-peanuts confection was said to have been introduced at the World's Columbian Exposition (1893). Supposedly a salesman gave it the name when he tasted some and said, "That's a cracker-jack," using the then-popular expression. The name was trademarked 1896. The "Prize in Every Box" was introduced 1912.

[late 1880s+; origin uncertain; perhaps a fanciful extension of cracker in the mid-19th-century British sense ''something approaching perfection,'' which is also reflected in terms like crack shot, crack troops, etc, and based on an echoic expression of speed; hence also cracking; the term is reinforced in the US by late 19th-century trademark Cracker Jack for a popcorn and peanut confection]
