The Library is named for Thomas Balch, who was born in Leesburg in 1821, the son of Judge Lewis P. Balch and Elizabeth Weaver. At age 5, he moved with his family to Frederick, Maryland, and later to Philadelphia. A noted attorney of his day, Thomas Balch was also a keen student of history throughout his life, becoming a corresponding member of numerous historical societies. He earned his own niche in history at the close of the American Civil War when his plan for resolution of the famous "Alabama Claims" resulted in a $15 million settlement for the United States against Great Britain and earned him the title of "Father of International Arbitration."

In 1922, the Thomas Balch Library was dedicated by his sons, Edwin Swift Balch and Thomas Willing Balch, who had donated $10,000 to build a public library in their father's memory to be located in the town of his birth. In recognition of Thomas Balch's lifelong love of history, the library was dedicated with a special requirement—that it maintain and foster a section dedicated to local history.


The Georgian Revival library building was designed by the noted Washington architect Waddy Wood. Wood is known for the design of the Woodrow Wilson House and Federal Triangle. In May 2001, a rededication ceremony was held to commemorate a new addition and the renovation of the Library. The Thomas Balch Advisory Commission and the Town of Leesburg chose the Bowie Gridley Architects firm of Washington, DC. A plaque at the Thomas Balch Library to Bowie Gridley reads: "Washington Chapter, The American Institute of Architects Merit Award"—Outstanding Achievement in Historic Resources, Thomas Balch Library, November 9, 2002. Bowie Gridley Architects." The certificate hangs in the foyer at the Library.

Mural and other works of art

Thomas Balch Library has been the recipient of numerous works of art, including sculpture, paintings, and a "A Loudoun County Story," a four-panel mural depicting the evolution of the region. The mural was commissioned by Friends of Thomas Balch Library, Inc., during the 2000-20001 renovation and expansion of the Library. It was installed in 2002 and made possible in part by a generous donation from Toll Brothers. The artist is William Woodward, a renowned artist and professor emeritus of Fine Arts at the George Washington University. He won the contract through a selection process that started with the solicitation of some 300 artists who were sent invitations resulting in 23 submissions.

Two additional paintings by William Woodward are also in the Library's collection. Meeting the Piscataway was made possible through a generous donation of Mr. and Mrs. Clarence Dodge, Jr.; Perseverance Through Faith and Strength was a gift of the Friends' Black History Committee to the Library. 

Friends of the Thomas Balch Library also commissioned Kurt Schwartz, a local artist residing in Waterford, to paint portraits of five individuals who played major roles in the life of Loudoun County: (below, left to right) Margaret Mercer, John Janney, John Elbert Divine, Westmoreland Davis, and Howard Willard Clark.
