Tennessee Celeste Claflin, Viscountess of Montserrat (October 26, 1844 – January 18, 1923), also known as Tennie C., was an American suffragist best known as the first woman, along with her sister Victoria Woodhull, to open a Wall Street brokerage firm, which occurred in 1870.

[5] Roxanna has been identified at various times as the niece of a prosperous saloon owner and as the illegitimate daughter of a maid.

[4] By 1860, Tennessee was advertised as a precocious fortune teller with the ability to cure diseases "from cold sores to cancer.

Authorities charged the family with nine crimes including disorderly conduct and medical fraud (quackery).

[10] In late 1869, Victoria Woodhull and Tennessee Claflin rented two rooms at the posh Hoffman House at 44 Broad Street in New York City.

[3] In an article entitled "Wall-Street Aroused," The New York Times questioned the sisters' potential for success, not because they were women, but because of their association with spiritualism and other unorthodox causes.

[3] Harper’s Weekly dubbed them "Bewitching Brokers" in a cartoon while another article in the magazine questioned whether there were enough female investors to make the firm a success.

Society wives and widows, teachers, small-business owners, actresses, and high-priced prostitutes and their madams sought out Woodhull, Claflin, & Company and the firm was an immediate financial triumph.

[11] Woodhull and Claflin used their newspaper to advocate for Free Love, a movement which in the nineteenth century pushed to separate sex from marriage.

As biographer Myra McPherson explained, “In arguing that a woman had a right to freedom regarding her own body, to choose her mate, to decide when she wanted sex, and actually to enjoy it, the sisters were so far ahead of the era that they were openly called prostitutes in print.”[11] Woodhull & Claflin’s Weekly was also the first paper in America to print The Communist Manifesto.

[2][16] Woodhull was nominated for President of the United States by the newly formed Equal Rights Party on May 10, 1872.

[19] On November 2, 1872, Woodhull & Claflin's Weekly published a report that triggered the famous adultery trial of Henry Ward Beecher.

[20] One hundred thousand copies of Woodhull & Claflin's Weekly were published on November 2, 1872 with "The Beecher-Tilton Scandal Case" on the cover.

Woodhull gave her sources as Elizabeth Cady Stanton, Isabella Beecher Hooker, and Paulina Wright Davis.

[5] In the same issues, Tennessee threatened further revelations about other important men by printing a letter from an anonymous madam who claimed to have recorded the names and addresses of her clients.

[14] Woodhull and Claflin spent the next few months in and out of jail on a variety of trumped-up obscenity charges brought by the rising vice crusader Anthony Comstock.

[11] Evidence suggests that the sisters' move was funded by the heirs of the recently deceased Cornelius Vanderbilt, who wanted them out of the way during a fight over the family inheritance.

[8] As the wife of a British baronet, Claflin was thereafter correctly styled "Lady Cook", and in Portugal was also Viscountess of Monserrate.

The couple lived at Doughty House in Richmond Hill, Surrey, now part of Greater London,[4] and at Monserrate Palace.
