Although the park was created to commemorate Private Finn’s death, the site conjured up memories of his father, Daniel E. Finn, also known as “Battery Dan,” who was a Tammany Hall politician and Democratic leader of Lower Manhattan (Fitzpatrick). Elder Finn earned fame through successfully opposing the construction of commercial piers Battery Park for the necessity for open space in a crowded neighborhood. His brave and honest actions in protecting community’s interests earned him the title “idealist” and “a friend of the people,” (Fitzpatrick).
Among the memorials of the Great War, Finn Square was the first park to be named after and dedicated to New York casualty of WWI (Fitzpatrick). During the regiment's 164 days of front-line combat, the total casualties amounted to 644 killed in action and 2,587 wounded (Harris). The park was dedicated to commemorate the lost lives in the war and remind the public about their sacrifices. Finn Square is no longer marked but a single plaque informs passersby of its brief historical significance. For almost 70 years, the park was neglected by the city. However, in April 1998, the park was revived under the leadership of Greenstreet who gathered community volunteers to plant flowers and maintain the garden (New York City Department of Parks & Recreation). This major transformation turned the untamed triangle into an attractive green space.
