Pendleton's Lithography (1825 – 1836) was an American lithography firm active in Boston during the early 19th century. The firm was founded by brothers John and William Pendleton when the acquired some lithographic material from a Boston merchant named Thaxter, who apparently acquired them in Europe but did not understand their use. The Pendleton's subsequently became the first lithographers in Boston. Their work was respected for portraiture, landscape prints, music covers, and other illustrations. John Pendleton left the firm in 1828 but it continued to operate under William. William sold the firm to his bookkeeper Thomas Moore, who changed the name but maintained the same business practices. IN 1840 Moore sold out to Benjamin W. Thayer. Pendleton's Lithography was based in three separate locations in BostonL: Harvard Place (1825-1826), Graphic Court (1826-ca.1832), and finally Washington Street (ca.1836).
