Amelie Posse

During her second marriage, some fourteen years she lived in Rome, and in Alghero, Sardinia, where she and her husband Oki were forced into exile for about one year due to the fact that during the First World War Oki, born in Pardubice being of Bohemian origin, of Austro-Hungarian nationality, was considered an enemy of Italy and so was his wife Amelie.

From this experience Amelie published her first book in 1931, Den oförlikneliga fångenskapen, which made her famous internationally in 1932 with the subsequent publication in English, Sardinian Sideshow, and after 66 years was also translated and published in Italian with the title Interludio di Sardegna in 1998.

The club was in fact inaugurated the same day Nazi Germany occupied Norway, on 9 April 1940.

Tisdagsklubben was to be used as the center of the Swedish resistance movement in case Sweden was ever occupied by Nazi Germany.

Amelie Posse was, like other members of the club, listed in German records as "Untrustworthy Swedes".
