American journalist and abolitionist (abolitionism) who countered vocal and sometimes physical opposition to her publications supporting women's rights (women's movement) and decrying slavery.

Jane Grey Cannon taught lace making from 1823 to help support her family, and she became a schoolteacher at age 14. In 1836 she married James Swisshelm, whose demand for her subservience contributed to her later devotion to women's rights. While living in Louisville, Kentucky, in 1838, she witnessed slavery firsthand and thenceforth was also dedicated to the abolition movement (abolitionism); for a short time she worked for the Underground Railroad.

Swisshelm's career in journalism began when she submitted stories and poems to Philadelphia papers in 1842, and in 1844 her first byline appeared in the Pittsburgh Spirit of Liberty. Her own abolitionist weekly, the Pittsburgh Saturday Visiter, first appeared in 1848. It soon advocated women's rights as well, but in a much less aggressive manner than most reformers of the time; Swisshelm urged women not to make unreasonable demands lest their entire movement be rejected. She further distinguished herself by insisting that women's rights and abolitionism be dealt with separately.

In 1850 Swisshelm made history as the first woman in the Senate press gallery. In 1857 she left both her husband and the Visiter to move to St. Cloud, Minnesota, where the following year she reestablished her paper as the St. Cloud Visiter. The venture was short-lived; a group of men supporting slavery destroyed her printing press in March 1858. By the summer of that year, however, Swisshelm had launched the St. Cloud Democrat in its place. She sold the business in 1863. During the Civil War she volunteered as a nurse and then retired to Swissvale, Pennsylvania, where she continued to write. Her memoirs, Half a Century, were published in 1880, after which she lived as a recluse.
