Tom Brenna was working in a Philadelphia office building when he noticed a black bag. The bag contained a book.
This chance discovery ended a 12-day search by the Library Company of Philadelphia for a historical treasure – a 120-page diary kept 190 years ago by Deborah Logan, “a woman who knew everybody in her day,” James Green, the librarian told the magazine American Libraries.
Most of the diary is a record of big events in Philadelphia. It is also includes a description of British soldiers burning Washington, D.C. in the war of 1812. She describes President James Madison on horseback as “perfectly shaking with fear” during the troubled days. George Washington, she writes, mistook her for the wife of a French man, and praised her excellent English.
