 Longacre had married Eliza Stiles in 1827 ; between 1828 , when their daughter Sarah was born , and 1840 , they had three boys and two girls . Sales of the Gallery lagged due to the Panic of 1837 ; Longacre was forced to declare bankruptcy and travel through the southern and midwestern states , peddling his books from town to town , with his wife and elder daughter managing shipping and finances at home . Later in 1837 , he was able to return to Philadelphia and open a banknote engraving firm with partners , Toppan , Draper , Longacre & Co . With great demand for engraving for notes being issued by state banks , the firm prospered , and had offices at 60 Walnut Street in Philadelphia and a branch at 1 Wall Street in New York . According to Snow , Longacre was known as the best engraver in the country .
