Laura Katharina Marholm (1854–1928) was a Baltic-German writer of literary criticism, biographies about women, and novels.

While using the pen name Leonhard Marholm, she wrote theatre reviews, articles, author biographies, and newspaper writings.

[3] Marholm's book Wir Frauen and unsere Dichter (1895) examined works that were written by men to determine what was considered masculine about women.

Six Modern Women: Psychological Sketches, a non-fiction book of biographies, was also published in 1895 and was translated into Swedish, Norwegian, English, Dutch, Russian, Polish, Czech, and Italian.

Three of the women who were written about within the work were Anne Charlotte Edgren Leffler, Amalie Skram, and Sonja Kovalevsky.

There was backlash against Six Modern Women because of traditional gender roles, with feedback that included "an absurd book" and "pathological eroto-mania".
