This park is named for David Sheridan, a member of an old prominent Riverdale family who was killed in World War II. Sheridan enlisted in the United States Army as a private in 1940, and reached the rank of Second Lieutenant. He died in 1945, killed in action on the Rhine River. Riverdale is located in the northwestern section of the Bronx, and west of the Henry Hudson Parkway. Once a railroad station called Riverdale-on-Hudson, the Riverdale area began to develop into a residential neighborhood during the 1930s, when mansions were built on the picturesque land that overlooked the Hudson River. Today, Riverdale is a thriving affluent neighborhood that has remained suburban despite heavily traveled thoroughfares that cut through the area as Riverdale Avenue.
