Lucius Quintus Cincinnatus Lamar
(b. Eatonton, Ga., 17 Sep. 1825; d. Macon, Ga., 23 Jan. 1893; interred St. Peter's Cemetery, Oxford, Miss.), associate justice, 1888–1893. Few Americans have enjoyed as extensive and diverse a public career as L. Q. C. Lamar. During the latter half of the nineteenth century, he served in all three branches of the national government, first as a member of the House of Representatives and Senate, then as secretary of the interior, and finally as an associate justice of the United States Supreme Court.
Born into the plantation aristocracy of middle Georgia, Lamar developed a strong patrician code that emphasized tradition, region, and propriety. Those values especially influenced his decisions in public office. Law and politics dominated his career. Over time Lamar practiced, taught, wrote, enforced, and interpreted law. As a professor at the University of Mississippi, moreover, he pioneered the case method approach to legal education. Political influence came primarily from his father‐in‐law, Augustus Longstreet, a college president and avowed separatist. Lamar authored the Mississippi ordinance of secession and resigned from Congress just before the onset of the Civil War. Yet years later, the same Lamar stirred Congress with impassioned pleas for reunification, earning him the reputation as the “Great Pacificator.” His eulogy of Massachusetts Senator Charles Sumner in 1874 is chronicled in Profiles in Courage by John F. Kennedy.
President Grover Cleveland in 1887 nominated his able interior secretary to fill the vacancy on the Court caused by the death of William B. Woods. Senate confirmation did not come easily. Opponents attacked Lamar on grounds of legal inexperience and advanced age, issues that shrouded partisan Republican politics. By a narrow vote of 42 to 38, Lamar took a seat on the high bench as the first southerner since his own cousin John A. Campbell (1853) and the first Democrat since Stephen J. Field (1862).
Lamar played a modest role on a Court faced with emergent issues of interstate commerce and state regulation of business. He almost always aligned with the majority, usually led by Chief Justice Melville W. Fuller. Until failing health limited his participation, Lamar wrote his fair share of assigned opinions. For the most part, however, he received inconsequential cases involving patent rights, land claim disputes, mortgage foreclosures, personal injury suits, and municipal bonds.
Arguably the most salient theme in his judicial philosophy emerged in three notable dissents involving the scope of national authority. In the landmark case of Chicago, Milwaukee & St. Paul Railway Co. v. Minnesota (1890), that ushered in a era of judicial activism, Lamar joined in a steadfast dissent that legislatures, not courts, should determine the reasonableness of public policy (see Judicial Self‐Restraint). Months later in what some scholars consider his finest opinion, In re Neagle (1890), Lamar challenged the expansion of executive power. Without explicit statutory authorization, he reasoned, a United States marshal who had defended a federal judge by killing an assailant may not claim to have acted in an official capacity. And in Field v. Clark (1892), Lamar charged that Congress had unlawfully delegated to the president its legislative power to impose discretionary tariffs (see Delegation of Powers). In these and all cases, Lamar followed personal values refined by political experience.
