Every schoolchild knows that the Liberty Bell is cracked; the crack is almost as famous as the bell itself. But just when and why the crack appeared is a much more esoteric matter. It is sometimes assumed, patriotically but mistakenly, that the bell cracked out of overenthusiasm while being rung to celebrate the Declaration of Independence in 1776. Somewhat more solid evidence suggests that it broke in 1835, either in July while tolling a knell for Chief Justice John Marshall or on Washington’s Birthday, when a group of small boys pulled too energetically on the rope. One of the boys, Emmanuel Rauch, was interviewed in 1911 and stuck to that story, observing besides that for any funeral the bell’s clapper would have been muffled and unlikely to cause damage. In 1846 an attempt was made to put the great bell in ringing order by drilling out the edges of the crack to prevent their rubbing together. This worked about as well as the dentistry characteristic of the period; and when the bell was rung on February 23 of that year (Washington’s Birthday having fallen on Sunday), the crack suddenly split open farther.
