The Congress was planned and organized by a committee created by the Pereire Society, a group that was against sign language. More than half of the people invited were known oralists; therefore, the Congress was biased and most, if not all, of the resolutions that were voted on by the delegates gave results in favor of the oral method. Many of the resolutions were worded in ways that supported the oral method, such as "Considering the incontestable superiority of speech over signs in restoring the deaf-mute to society, and in giving him a more perfect knowledge of language,/Declares –/That the Oral method ought to be preferred that of signs for the education and instruction of the deaf and dumb".[19] Until the 1890s, deaf education in the United States was limited to children, but Lillie Eginton Warren and her assistant, Edward B. Nichie, expanded the teaching to adults.[20]
