-The Famous Crack-
There are no records of why or when the Bell first cracked. It is widely believed that the crack developed after about 90 years of use in the early 1840's. Metalworkers started repairing it in 1846 in preparation for George Washington's birthday holiday. The crack was widened so the cracks wouldn't spread. The repair failed, however, as a second crack developed, silencing the bell forever.
