A Harvest of German Verse is a collection of German poems, selected and translated by Margarete Münsterberg, with a foreword by Kuno Francke, printed 1916 in New York. It contains a few poems and poets which probably never have been translated into English by anyone else.
I could not find out much about Margarete Anna Adelheid Münsterberg. She was born in 1889 in Freiburg, Germany, the daughter of psychologist Hugo Münsterberg, whose biography she wrote in 1922. She wrote at least two novels, Anna Borden’s Career (1913) and Red Poppies (1915). About her further life, nothing is known.
