Jasper Yeates

Jasper Yeates (1745–1817) was a lawyer and judge from Pennsylvania, a justice of the state Supreme Court from 1791 to 1817.

Jasper Yeates was born in Philadelphia on April 9, 1745 to John and Elizabeth Sidebotham Yeates. He graduated from the College of Philadelphia with a Bachelor of Arts in 1758 and later received a Master of Arts degree. He studied law and was admitted to the Bar of Philadelphia in 1765. He traveled to England to study at the Inns of Court for his legal training, as was typical of other colonial aspiring families.

His career began in Lancaster, Pennsylvania, west of Philadelphia where he became a prominent member of the bar. On December 30, 1767 he married Sarah Burd, eldest daughter of Colonel James Burd and his wife Sarah Shippen. During the American Revolution, he sided with the Patriot cause. In 1776, he served as a commissioner to investigate Native American affairs in Pittsburgh. Yeates was a prominent lawyer in Lancaster and during his career he built a fine library of legal books in several languages totaling 1,043 volumes in all. Most were purchased in Dublin and London. The library today is housed in its entirety in the library of LancasterHistory.org in Lancaster, Pa. where it is available for scholarly research.

After the Revolution, Yeates was a delegate to the Pennsylvania convention that ratified the United States Constitution in 1787.

Appointed as a justice on the Pennsylvania Supreme Court in 1791, he served until his death in 1817. A Federalist, he was appointed by the Washington administration in 1794 to serve on a commission sent to negotiate an end to the Whiskey Rebellion. Yeates died in Lancaster, Pennsylvania on March 14, 1817 and is buried in St. James Episcopal Church cemetery along with his wife Sarah, who died October 25, 1829.
