Two insurance policies in the KDSC archives issued by the Firemen’s Insurance Company of New York (seen below) from 1832 and 1836 include the signature of the company’s president, John Leonard. Insurance may not have been the only industry Mr. Leonard was involved in. An article from the New York Tribune written on May 1st, 1841 may reveal that Mr. Leonard was involved in patenting tailor’s shears. The article states that the U.S. Circuit Court was involved in a case entitled “Rochus Heisiesch vs. John Leonard and Herman Wendt,” regarding the “infringement of a patent right for an improved fashion of tailors’ shears.” It is uncertain whether the John Leonard involved in the case is indeed John Leonard, former president of the Firemen’s Insurance Company of New York.
The insurance policy signed by Leonard in 1832 also includes the signature of James W. Bleeker. Those involved in the New York Stock Exchange may recognize this name, as Bleeker served as the NYSE’s 4th president from 1827 to 1830.
