[3] In 1912, Hendley founded the Anthony League to preserve the history of the woman's suffrage movement, and to build support for a memorial to Susan B. Anthony in Washington, D.C.[4] The group also took positions on education, child labor, marriage laws, and prison reform.

[7][8] She was president of the organization for fourteen years; it changed its name to the Susan B. Anthony Foundation in 1925.

[1] She also owned a large 1890 portrait of Anthony by S. Jerome Uhl,[14] and hung it at the Foundation's headquarters in the Shoreham Hotel.

The painting was presented to the League of Women Voters by 1932,[15] and to Woodrow Wilson High School in 1938; it has since disappeared.

[16] Anna Elizabeth Mills married federal employee Julian Paul Hendley in 1882.
