Heinrich Vogeler’s (not to be confused with Heinrich Max Vogel) work appeared a few times in Jugend. Here are a couple paintings by Vogeler. I like the translucence of the girls’ dresses and the way they seem to be dancing in the first one. I wonder if this piece was influenced by Isadora Duncan’s little dancers. Remember, Duncan opened her first dance school in Grunewald, Germany in 1904, and there is a cartoon of Duncan with some of her young students in one of the 1904 issues of Jugend. Anyway . . .
Note how Vogeler transitions from pure Impressionism to a more Expressionistic style over the years. A lot of new styles were emerging in the late Victorian period and throughout the first half of the twentieth century, and artists from that era often experimented with a number of them. Gauguin really set the tone for this, I think.
