Has there been a popular park or a recreation
center named after a deaf person?

The Gertrude Ederle Recreation Center in
Manhattan (New York City) is named after
Gertrude Ederle, a deaf woman, who was
the first woman to swim across the English
Channel. She achieved that feat in 1926.

It is located on the block between
West 59th Street and West 60th
Street, between Amsterdam Avenue
and West End Avenue.
