Zoia Horn

Zoia Markovna Horn was an American librarian who in 1972 became the first United States librarian to be jailed for refusing to share information as a matter of conscience. Horn, an outspoken member of the American Library Association's Intellectual Freedom Committee, worked at Bucknell University in Lewisburg, Pennsylvania, in the early 1970s. Horn was jailed for nearly three weeks for contempt of court after refusing to testify for the prosecution in the 1972 conspiracy trial of the "Harrisburg Seven" anti-war activists.
