Das Vergissmeinnicht "The Forget-Me-Not"
The True Story Behind This Beloved
Emblem of the craft in Germany
As early as the year 1934, soon after Hitler's rise to power, it became apparent that Freemasonry was in danger. In the same year, the German Grand Lodge of the Sun in Bayreuth (one of the pre-war German Grand Lodges) realised the imminent problems facing them and elected to waer a little blue flower, The Forget-Me-Not (Das Vergissmeinnicht) in lieu of the traditional Square and Compasses, as a mark of identification for masons. It was felt the new symbol would not attract attention from the Nazis, who were in the process of confiscating and
appropirating Masonic Lodges and property. Masonry had gone underground and it was necessary that the Bretheren have some readily recognizable means of identification.
Throughout the entire Nazi era, a little blue flower in a lapel marked a Brother. In the Conzentration Camps and in the cities a little blue Forget-Me-Not distinguished the lapels of those who refused to allow the Light of Masonry to be extinguished.
In 1947, when the Grand Lodge of the Sun was reopened in Bayreuth by Past Grand Master Beyer, a little blue -Forget-Me-Not- pin was proposed and adopted as the official emblem of the first annual convention of those who survived the bitter years of darkness bringing the Light of Masonry once again into the Masonic Tempels.
At the first Annual Convent of the United Grand Lodges of Germany, AF & AM in 1948, the pin was adopted as an official Masonic emblem honoring those valiant Bretheren who carried out their work on under adverse conditions. At the Grand Masters Conference in the United States, Dr. Theodor Vogel, the Grand Master of the newly formed VGLvD, presented one of the pins to each of the representatives of the Grand Jurisdictions of which the VGLvD enjoyed fraternal relations.
Thus did a simpel flower blossem forth into meanningful emblem of Fraternity and became perhaps the most widly wom pin among freemasons in Germany. In most lodges, the Forget-Me-Not is presented to a new Master Mason, at which time its history is briefly explained.
