Samuel Freeman Miller (April 5, 1816 – October 13, 1890) was an American lawyer and physician who served as an associate justice of the U.S. Supreme Court from 1862 until his death in 1890. Early life, education, and medical career Born in Richmond, Kentucky, Miller was the son of yeoman farmer Frederick Miller and his wife Patsy. He earned a medical degree in 1838 from Transylvania University in Lexington, Kentucky. While practicing medicine for a decade in Barbourville, Kentucky, he studied the law on his own and was admitted to the bar in 1847. Favoring the abolition of slavery, which was prevalent in Kentucky, he supported the Whigs in Kentucky. Career In 1850, Miller moved to Keokuk, Iowa, which was a state more amenable to his views on slavery, and he immediately freed his few slaves who had come with his family from Kentucky. Active in Iowa politics, he supported Abraham Lincoln in the 1860 election. Lincoln nominated Miller to the Supreme Court on July 16, 1862. He was confirmed by the U.S. Senate that same day, and was sworn into office on July 21. His opinions strongly favored Lincoln's positions, and he upheld his wartime suspension of habeas corpus and trials by military commission. After the war, his narrow reading of the Fourteenth Amendment—he wrote the opinion in the 1873 Slaughterhouse Cases—limited the effectiveness of the amendment. Miller wrote the majority opinion in Bradwell v. Illinois, which held that the right to practice law was not constitutionally protected under the Privileges or Immunities Clause of the Fourteenth Amendment. He later joined the majority opinions in United States v. Cruikshank and the Civil Rights Cases, holding that the amendment did not give the U.S. government the power to stop private—as opposed to state-sponsored—discrimination against blacks. In Ex parte Yarbrough, 110 U.S. 651 (1884), however, Miller held that the federal government had broad authority to act to protect black voters from violence by the Ku Klux Klan and other private groups. Miller also supported the use of broad federal power under the Commerce Clause to override state regulations, as in Wabash v. Illinois. Justice Miller wrote 616 opinions in his 28 years on the Court; Justice Field (whose 34 year SCOTUS tenure mostly overlapped Miller's) wrote 544 opinions; Chief Justice Marshall wrote 508 opinions in his 33 years on the Court, leading future Chief Justice William Rehnquist to describe him as
