A seemingly simple math problem about the ages of Mary and Ann, first published around 1903, captivated the nation, appearing in newspapers like the New York World and the New York Times. The puzzle, which asks "Mary is 24 years old. She is twice as old as Ann was when Mary was as old as Ann is now. How old is Ann?", sparked widespread discussion and a variety of incorrect answers.

This "How Old Is Ann?" phenomenon became a cultural sensation, inspiring songs, theatrical productions, and even cartoons. People from all walks of life, including policemen and prominent citizens, offered their solutions, highlighting the puzzle's perplexing nature. Some, like Frank R. Shattuck, confidently declared Ann was 12, while others, like Timothy P. Sullivan, arrived at 19. A correspondent for the Kansas Journal even claimed Ann was 63.

Despite its initial popularity, the craze proved short-lived. By December 1903, the puzzle was being humorously advertised as missing, signaling the end of its brief but memorable reign in public consciousness.
