What did Elmer Johnson help the National FFA develop?

Elmer Johnson played a significant role in helping the National FFA develop its archives. Archives are essential for preserving the history and legacy of an organization, ensuring that important documents, records, photographs, and materials are maintained for future generations. Through establishing a well-organized collection of historical items, Elmer Johnson contributed to the National FFA’s ability to reflect on its past, honor its traditions, and educate members about the organization's origins and evolution. This focus on historical preservation supports the FFA's mission of developing leaders and building strong communities by fostering an understanding and appreciation of the agricultural education movement's roots.

The other options focus on different aspects of organizational development. While someone may have worked on curriculum development, membership programs, or leadership training, Elmer Johnson's specific contributions were centrally focused on archives. This distinguishing factor highlights the importance of recorded history within the agricultural community and the FFA itself.
