Pinckney H. Walker, born in Kentucky, moved to Rushville, Ill., in 1834, and then to Macomb, where he read law with his uncle, Cyrus Walker. After his admission to the bar, he practiced in each town. Elected to the circuit court, 5th circuit, in 1853, he was appointed and then elected to the Illinois Supreme Court in 1858, to the first of three nine-year terms.
This collection contains two pocket notebooks used by Walker to record notes for his judicial opinions in 1860 and 1861. The Illinois Historical Survey acquired these notebooks in 1942.
