John Chipman Gray (July 14, 1839 – February 25, 1915) was an American scholar of property law and professor at Harvard Law School. He also founded the law firm Ropes & Gray, with law partner John Codman Ropes. He was half-brother to U.S. Supreme Court associate justice Horace Gray, and a grandson of merchant and politician William Gray.
Gray was born in Brighton, Massachusetts to Horace and Sarah Russell (Gardner) Gray, and graduated from Boston Latin School. From there, he went on to Harvard University, where he earned his Bachelor of Arts degree in 1859, and Harvard Law School, where he earned his law degree in 1861. Gray''s politics, prior to the Civil War tended toward the Whig Party. However, he transited into the Know-Nothing Party when the Whigs collapsed. Although he became a Republican, he opined, while serving as a judge advocate, that President Abraham Lincoln did not possess the constitutional authority to issue the Emancipation Proclamation.[1] However, when the Civil War began, he argued that the defeat of slavery was imperative for the survival of the nation.
