High Quality Content by WIKIPEDIA articles! Isaac Newton Blackford (November 6, 1786 – December 31, 1859) was the second Chief Justice of the Indiana Supreme Court, the court`s longest serving Justice, and among the longest serving jurists in the history of the United States. He wrote an eight volume work entitled Blackford`s Reports recording all the early decisions of the court. The books became a staple legal source among Indiana’s lawyers and received national and international acclaim for its style, accuracy, quality, and concision in dealing with common law. As a jurist, Blackford was the most influential ever to serve on Indiana`s courts, according to current Chief Justice Randall Shepard. He was nickname the "Indiana Blackstone" because of a comment made by Washington Irving regarding the popularity of Blackford’s books. During his lifetime he was nationally renowned as one of the most prominent jurists in the United States.
