The "Yankee" Jewish women of the first half of the twentieth century created the infrastructure of American-Jewish women's organizational activities. The founding of synagogue sisterhoods began with the Reform National Federation of Temple Sisterhoods in 1913, followed by the Women's League for Conservative Judaism in 1918, and the two Orthodox sisterhoods, Mizrachi Women’s Organization of America (AMIT) in 1925 and Emunah in 1935. Pictured here is the Orthodox Congregation B'nai David Sisterhood of Detroit, Michigan, ca. 1950. Among those seated are Rebbetzin Yetta Sperka (top left), wife of the synagogue Rabbi Joshua Sperka; Mrs. Hyman Adler (top right), wife of the congregation's cantor; and Mrs. David J. Cohen (second row, center).
