Original Note:
This wasn't the Rockefellers (or the Nazis). The change was suggested by the American Standards Association in 1936. In 1955 the International Standards Organization made the 440 Hz A their ISO 16. There is nothing magical about either tuning standard. https://skeptoid.com/episodes/4474 https://www.reuters.com/article/factcheck-musical-pitches-idUSL1N2P915O
