Here we have the photo that would have Rudolf Steiner in it (#19). Not so! This photo was in all likelihood taken during the 1927 international convent of Le Droit Humain in Paris.
The photo with names came from a drawer of the Finish federation of Le Droit Humain. They also added some names. Ironically they mistook their own representative for Steiner!
I was a bit confused to not find the Dutch representative in this photo. In 1924 Franz Farwerck became Dutch representative, yet according to the report of the Dutch federation, somebody else was supposed to go. The same report said that due to the number of members of the Dutch federation, only one representative was allowed. Still, the French Bulletin of this time lists two Dutch names:
Farwerck and Sister Schlesinger-Kerdijk. Neither was the supposed Dutch representative, but Kerdijk went as stand-in. She was also present during the first international convent of 1920.
A bit odd in the story is that there are two Fins on the photo while the Finish federation was considerably smaller than the Dutch one. Apparently the Dutch were more led by the rules than other federations.
So, the Finish photo filled in some names. I can add two myself.
03. Ellen Brille Brahe (Marie Antoinette von Lowzow) (Denmark)
08. Amelie André Gedalge (France)
10. Eugène Piron (Grand Master / France)
11. Annie Besant (UK)
12. Louis Goaziou (USA)
14. Anne Schlesinger-Kerdijk (Netherlands)
19. F. Vitikka (Finland)
20. Blanche Mesagne (France)
24. Pekka Ervast (Finland)
29. James Ingall Wedgwood (UK)
Who’s helping to fill in more names? I have a high resolution of the photo, so I can provide details if needed.
