Sarah Margaret Fuller Ossoli was an American journalist, editor, critic, translator, and women's rights advocate associated with the American transcendentalism movement. She was the first American female war correspondent, writing for Horace Greeley's New-York Tribune, and full-time book reviewer in journalism. Her book Woman in the Nineteenth Century is considered the first major feminist work in the United States.
Born Sarah Margaret Fuller in Cambridge, Massachusetts, she was given a substantial early education by her father, Timothy Fuller, who died in 1835 due to cholera. She later had more formal schooling and became a teacher before, in 1839, she began overseeing her Conversations series: classes for women meant to compensate for their lack of access to higher education. She became the first editor of the transcendentalist journal The Dial in 1840, which was the year her writing career started to succeed, before joining the staff of the New-York Tribune under Horace Greeley in 1844. By the time she was in her 30s, Fuller had earned a reputation as the best-read person in New England, male or female, and became the first woman allowed to use the library at Harvard College.
