About Thomas Mundy Peterson Park
The park honors Thomas Mundy Peterson, the first African-American in the entire U.S. to cast a vote under the 15th Amendment to the U.S. Constitution.
Although enslaved African-Americans had been freed by the 13th Amendment in 1865, the 15th Amendment was ratified in 1870 to extend voting rights to men (not women) of all races. However, after the 15th Amendment, many African-Americans throughout the U.S. were still denied the right to vote by state constitutions & laws, poll taxes, literacy tests, and outright intimidation.
Yet, on March 31, 1870, Peterson was allowed to vote in Perth Amboy.
While in this park, check out the informative Arthur Kill sign towards the water. Then look across the water, to the north, to spot the Tottenville station of the Staten Island Railway, which ends at Saint George for the Staten Island Ferry.
