The Age of Jackson
Farmers found their work eased by 
such inventions as John Deere’s steel 
plow (1837) and Cyrus McCormick’s 
automatic reaping machine (1831), 
which replaced workers who had 
previously cut grain with hand-held 
scythes. 
In 1844 an American inventor, 
Samuel F. B. Morse, developed a 
working model of the fi rst magnetic 
telegraph. This invention provided 
instant communication over long 
distances, something never previously 
achieved in the history of humankind. 
While the inventor of the cotton 
gin, Eli Whitney, had also pioneered 
the manufacturing system that relied 
on interchangeable parts in gun 
manufacture, it was Samuel Colt who 
made the fi rst successful, repeating 
revolver (1836) using interchangeable 
parts.
Everything from the sewing 
machine (1846) to the rotary printing 
press (1847), suspension bridges 
spanning major rivers (1847), an 
effi cient steel-making process (1852), 
the passenger elevator (1853), and 
the vacuum evaporator for canning 
food products with a long shelf life 
(1846) came into reality during the 
years prior to the Civil War. America 
became more reliant on such 
inventions for quicker transportation, 
better communication, and greater 
productivity.
percent!  The  money  supply  was  infl ated.  Businesses  were 
overextended. The Bank of the United States called in piles 
of loans, including those to states that had borrowed to pay 
for internal improvements, such as canals and railroads. The 
Bank of the United States and other Eastern banks refused to 
accept paper money for debt payments. State banks, having 
dramatically  overextended  themselves,  were  driven  out  of 
business. The Panic of 1837 loomed across the country.
An Economic Mess
Perhaps ironically, Jackson was not blamed for the economic 
collapse, even though it was partially of his making. Many 
factors, including bank collapses, did not kick in until the
