A cracker is a thin and crispy piece of baked bread. Crackers can be eaten by themselves, but they can also be eaten with things on them called toppings. Common toppings include cheese, peanut butter, and sliced meats. Crackers are most often eaten as a snack, or crumbled into soup.
It was 1792 when Theodore Pearson of Newburyport, Massachusetts, made a cracker-like bread that was made from only water and flour which he called "Pearson's Pilot Bread." This was the first cracker bakery in the United States, and made crackers for more than a century.
