Sarah Margaret Fuller Ossoli, commonly known as Margaret Fuller, (May 23, 1810 – July 19, 1850) was an American journalist, critic, and women's rights advocate associated with the American transcendentalism movement. She was the first full-time female 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. She later had more formal schooling and became a teacher before, in 1839, she began overseeing what she called "conversations": discussions among 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, 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. Her seminal work, Woman in the Nineteenth Century, was published in 1845. A year later, she was sent to Europe for the Tribune as its first female correspondent. She soon became involved with the revolution in Italy and allied herself with Giuseppe Mazzini. She had a relationship with Giovanni Ossoli, with whom she had a child. All three members of the family died in a shipwreck off Fire Island, New York,..
