Seymour “Sy” Seplowe was a community activist and youth advocate. He was born in the Bronx, served in World War II, then settled in northeastern Queens during the early 1950s. Seplowe organized the Little Neck-Douglaston Memorial Day Parade and, in 1953, founded the Little Neck-Douglaston Youth Club, an organization of 1,200 members dedicated to providing community youth with athletic opportunities. Seplowe was also a founding member of Community Board 11 and the president of the Little Neck-Douglaston Community Council. Throughout his life, Seplowe worked to promote baseball, and served as the Little League administrator for School District 26 for 35 years.

In 1951, the City of New York acquired the land adjacent to P.S. 94 and constructed a park for the school’s use. The City named the new park in honor of Seplowe. In 1985, Parks renamed the property Admiral Park; however, the playground within the park continues to be known as Sy Seplowe Playground.
