July 4, 1915 was 139 years after July 4, 1776.
In 1915, 500,000 schoolchildren signed a petition asking the city of Philadelphia to send the Liberty Bell to the Panama-Pacific International Exposition of San Francisco.
During World War I, the Liberty Bell made a trip from Philadelphia by railroad, including the
train station outside
Elizabethtown, PA. It reached the west coast and then returned to Philadelphia where it has been ever since.
It was the Liberty Bell's last trip outside Philadelphia. Jacob N. Olweiler arranged for the Bell to stop in Elizabethtown.
