The small blue forget-me-not flower was first used by the Grand Lodge Zur Sonne, in 1926, as a Masonic emblem at the annual convention in Bremen, Germany. In 1938 the forget-me-not badge – made by the same factory as the Masonic badge – was chosen for the annual Nazi Party Winterhilfswerk, a Nazi charitable organisation which collected money so that other state funds could be freed up and used for rearmament. This coincidence enabled Freemasons to wear the forget-me-not badge as a secret sign of membership.
After World War II, the forget-me-notflower was again used as a Masonic emblem at the first Annual Convention of the United Grand Lodges of Germany in 1948. The badge is now worn in the coat lapel by Freemasons around the world to remember all those that have suffered in the name of Freemasonry, especially those during the Nazi era.
