Inez Milholland Boissevain (August 6, 1886 – November 25, 1916) was a leading American suffragist, lawyer, and peace activist.
From her college days at Vassar College, she campaigned aggressively for women’s rights as the principal issue of a wide-ranging socialist agenda. In 1913, she led the dramatic Woman Suffrage Procession on horseback in advance of President Woodrow Wilson's inauguration as a symbolic herald. She was also a labor lawyer and a war correspondent, as well as a high-profile New Woman of the age, with her avant-garde lifestyle and belief in free love. She died of pernicious anemia on a speaking tour, traveling against medical advice.
