The practice of referring to married women by their husband's first and last names, which only died out in the late 20th century, has been criticized since the 19th century. When the Reverend Samuel May "moved that Mrs Stephen Smith be placed on a Committee" of the National Women's Rights Convention in Seneca Falls, Lucretia Mott quickly replied: "Woman's Rights' women do not like to be called by their husbands' names, but by their own". Elizabeth Cady Stanton refused to be addressed as "Mrs Henry B. Stanton". The practice was developed in the mid-18th century and was tied to the idea of coverture, the idea that "By marriage, the husband and wife are one person in law; that is, the very being or legal existence of the woman is suspended during the marriage."
