Lucie Marie Ludovika Anastasia Adelheid Karola Hedwig Reventlow (1884–1984) was a German-born Danish philanthropist who is remembered for supporting the scout movement in Denmark. In particular, she adapted her home, Brahetrolleborg Manor on the island of Funen, as a scouting school. In addition, she created a housekeeping school on the premises. After spending the Second World War in England, where she served in the Air Raid Precautions, she returned to Brahetrolleborg, upholding its historical traditions until she died, almost 100 years old.
