Louise M. Shadduck (October 14, 1915 – May 4, 2008), also called the "Lioness of Idaho," was an Idaho journalist, political activist, public servant, author, speaker and lobbyist, and the first woman in the United States to serve at the state cabinet level. As Idaho's popular Secretary of Commerce and Development, often leading visiting business executives on horseback adventures in the mountains, she stimulated the state's economy to its ten best years of growth. She was also administrative assistant to two governors, a U.S. Senator and a Congressman.
