Digital Restoration: The Normandy Liberty Bell

 

The Story:
The Liberty Bell is one of America’s most iconic and important symbols always representing independence, freedom and equality. The bell was first cast in London in 1752, but cracked while it was being hung to test the sound. A second bell was cast locally and was quickly raised in Pennsylvania’s Statehouse Steeple in 1753.

The famous bell tolled throughout the history of colonial Pennsylvania and the early United States, marking historical moments such as the Boston Tea Party, the signing of the Declaration of Independence and the ratification of the Constitution.

Nearly 100 years after the bell was cast, the bell had begun to crack. In February of 1846, while being rung in commemoration of Washington’s Birthday, the bell retained the crack that we are all familiar with today.  The infamous cracked bell traveled the country visiting expositions, celebrations and the Chicago World’s fair. The bell was continually “tapped” to symbolize liberty and independence on monumental occasions such as the 150th Anniversary of American’s independence and on the WWII D-day invasion of Normandy.

The Challenge:  
Direct Dimensions was given the task of creating an exact digital replica of the Liberty Bell that would be cast to look and sound before it cracked in 1846.                                                                                                                                                                                                                                                                          return to full slide show

The Solution:

• 3D scan the bell on-site using multiple types of scanners
• Compile the data to create a high-resolution digital replica of the bell
• Measure an average thickness of the bell while working with experts to determine the dimensions of the 1753 bell
• Create a 3D surface model of the bell as it  would have looked with no crack nor other defects from casting and aging
  
• Send the final data to Cornille- Havard bell foundry in France where they cast the bell used the traditional methods used by Pass & Stow in casting the original bell                                                                                                                                                                                                                                        return to full slide show
