Want to write a new Wikipedia article but can’t think of a subject not
already covered? Here are some items that are notable and
should be easy to source:

  movement and designer of playgrounds, including the famous one in
  New York’s Central Park near 67th Street.

  case that held that while cookbooks are protected by copyright,
  the recipes themselves are not.
