Leo Tolstoy was so influenced by Mallory's magazine, the monthly spiritualist,[2] The World's Advance Thought,[3] that he called her the "greatest woman in America".

[8][11] On June 24, 1860, she married Rufus Mallory,[12] who afterwards represented Oregon in Congress, and who was later one of the most successful lawyers in the Pacific Northwest, and was the senior member of the extensive law firm to which Senator Joseph N. Dolph belonged.

[4][8][11] In 1874, the old slavery prejudice was so strong in Oregon that some forty-five African American and mulatto children were prevented from attending the Salem public schools and kept from all chance of acquiring an education, as no Caucasian teachers would condescend to teach them.

Her course shamed the people into a sense of duty, and within three years, friction and opposition ended, and the children were admitted into the public schools and classes.

[4][8][11] In 1886, she used the fund for the purchase of a printing plant, and soon after, started her monthly magazine, the World's Advanced Thought, with Judge Horatio N. Maguire for assistant editor.

After Maguire retired from editorial connection, on account of the pressure of other business affairs, he still contributed to its pages, while Mallory, who was always the proprietor, had full control.

In addition to her reading room and periodicals, Mallory kept parlors open for meetings held twice or three times a week.
