Henrietta Skelton (née, Hedderich; pen names, H. S.; Madame Skelton; November 5, 1839/1842 – August 22, 1900) was a 19th-century German-born Canadian-American social reformer, writer, organizer, and lecturer in the German Spanish, and English languages. She was the superintendent of the German work for the National Woman's Christian Temperance Union (NWCTU), and president of the State Union of Idaho,[1] In that capacity, she traveled all over the United States, lecturing in English and German, and leaving behind her local unions of well-organized women. Skelton's name was known by thousands of German citizens of the United States as one of the most dedicated workers in the temperance movement. For a time, she edited the temperance paper known as Der Bahnbrecher, besides writing several books published in the English language, including The Man-Trap (Toronto), a temperance story; Clara Burton (Cincinnati), a story for girls; and The Christmas Tree (Cincinnati), a description of domestic life in Germany.[2] Skelton died in 1900.
