The first periodical dedicated to male homosexuality, Der Eigene was published from 1896 to 1932 in Berlin. Remarkable not only for the subject matter but for the longevity and philosophy of its editor and publisher Adolf Brand. Germany made same sex relations illegal with the passage of "paragraph 175" in 1871 a law that was not revoked until 1994!
The magazine included lyric poetry, prose, political manifestoes as well as reproductions of the male nude figure as represented in art, sculpture and photography. Posted here is the only example of Der Eigene I have been fortunate to own. From 1906 a bound volume with four issues including artworks and photographs by the Baron Wilhelm von Gloeden.
