Series I. James O’Hara Papers, 1777-1880

Scope and Content Notes:

James O’Hara (1753-1819) left his home in County Mayo, Ireland, in 1773 to settle in Philadelphia. In 1774, he was appointed a government Indian agent, and traveled to western Pennsylvania where he traded with Indians at Fort Pitt on behalf of an eastern company, and purchased extensive lands from the federal government. In 1788, James became the second president of the Bank of Pennsylvania, and two years later he wed Mary Carson (1760-1834) of Philadelphia, and brought her to Pittsburgh. George Washington appointed him Quartermaster General of the United States Army in 1792. During his military career, James served in western Pennsylvania to quell the Whiskey Rebellion and in General Anthony Wayne’s expedition against the Western Confederation. Anne Hemphill Herbert notes that James is credited with "saving the army with his efficient business methods and remarkable understanding of the Indian character and their various dialects."

In 1793, James purchased land at the forks of the Ohio from the United States government, and four years later he and his partner, Major Isaac Craig, built the first glass works in America on the southern banks of the Monongahela River. James became Pittsburgh’s first burgess and was a founder of the First Presbyterian Church. Materials in this series provide information on early frontier life in Pennsylvania through various personal and professional letters as well as official government reports. Also included are copies of James and Mary O’Hara’s wills, which are critical in understanding the inheritance of significant property holdings that are now important to Pittsburgh’s history, including Schenley Park and the Fort Pitt Block House. Accompanying these materials is H.M. Brackenridge’s critique of James O’Hara’s will. An obituary of James O’Hara and newspaper articles describe his role in the early development of Pittsburgh and his dealings with the Indian tribes. James O’Hara’s papers have been divided into subseries that separate personal and business papers from materials describing his legacy and estate.
