Bertha Eckstein-Diener

Bertha Eckstein-Diener (18 March 1874, Vienna – 20 February 1948, Geneva), also known by her American pseudonym as Helen Diner, was an Austrian writer, travel journalist, feminist historian and intellectual.

[1] She was a member of the "Arthurians," a group of European intellectuals active in the 1930s, each of whom adopted a name from Arthur's Round Table (Diner was Sir Galahad).

Diner set out to document a feminist history of women, and infused her book Mothers and Amazons (Mütter und Amazonen) with lyrical and poetic language.

Her 2nd son, Roger (born 1910) was fathered by Theodore Beer, but was placed with a foster family and did not make contact again with his mother until 1936 by letter and in person only in 1938 in Berlin.

Besides her books, she wrote a series of articles for newspapers and magazines and translated three works of American journalists and the esoteric writer Prentice Mulford.
