and Men (1888), he advocated equality of opportunity and equality of rights for men and women. In 1874, Higginson was elected a member of the American Antiquarian Society. In 1891, Higginson became one of the founders of the Society of American Friends of Russian Freedom (SAFRF). He edited its public appeal "To the Friends of Russian Freedom". Later, in 1907 Higginson was the vice-president of the SAFRF. In 1905, he joined with Jack London, Clarence Darrow, and Upton Sinclair to form the Intercollegiate Socialist Society. Higginson was an Advisory Editor for the second attempt at the Massachusetts Magazine. Higginson died May 9, 1911. Although his death record states that he was buried at Mount Auburn Cemetery in Cambridge, Massachusetts, he is actually buried in Cambridge Cemetery in Cambridge, Massachusetts at the intersection of Riverview, Lawn, and Prospect paths. Beliefs Higginson's deep conviction in the evils of slavery stemmed in part from his mother's influence. He greatly admired abolitionists, who, despite persecution, showed courage and commitment to the worthy cause. The writings of William Lloyd Garrison and Lydia Maria Child were particularly influential to Higginson's abolitionist enthusiasm during the early 1840s. Higginson claimed that Child's book, An Appeal in Favor of That Class of Americans Called Africans, first convinced him to speak against slavery. Homeopathy Higginson was a strong advocate of homeopathy. In 1863, he wrote to his wife Mary Channing Higginson: "and also Ms. Laura Towne, the homeopathic physician of the department, chief teacher and probably the most energetic person this side of civilisation: a person of splendid health and astonishing capacity....

Emily Dickinson, a 32-year-old woman from Amherst, Massachusetts, sent a letter to Higginson, enclosing four poems
