Path to the Supreme Court
Gabriel Duvall reached the Court in 1811 with a résumé nearly as old as the Republic: clerk to Maryland's revolutionary conventions, state legislator, congressman, judge of the state's General Court, Jefferson elector, and for nine years the first Comptroller of the United States Treasury. Madison nominated him and Joseph Story (§18) together, and the Senate confirmed both the same November day — Duvall at fifty-eight, Story at thirty-two. No two careers ever diverged more completely from a shared beginning.
On the Supreme Court
Twenty-three years yielded perhaps fifteen quiet commercial opinions — and one immortal sentence. When Mima Queen v. Hepburn closed the courtroom door on hearsay proof in freedom suits, dooming petitioners whose only evidence of a free ancestress was community memory, Duvall dissented alone: 'It will be universally admitted that the right to freedom is more important than the right of property.' In Le Grand v. Darnall he wrote for the Court that a master's bequest of property to his slave freed the man by necessary implication. Deaf and failing in his last years, he held the seat until January 1835, resigning only when assured that fellow Marylander Roger Taney (§24) would be nominated to it. He died in 1844, at ninety-one.

No biography of Gabriel Duvall exists. The best place to start is William G. Thomas III's A Question of Freedom (Yale, 2020) — not a Duvall biography but the acclaimed history of the Maryland freedom suits, in which Duvall appears in two roles a novelist would hesitate to invent: the young lawyer who won freedom suits for members of the Queen family in the 1790s, and the justice who cast the lone dissent when Mima Queen's case reached the Supreme Court in 1813.
The Bookshelf
The story of the Queen, Butler, and Bell families, who sued for their freedom in Maryland and Washington courts for three generations. Duvall runs through it first as the Annapolis lawyer who argued — and won — freedom suits for the Queen family, then as the Supreme Court justice who dissented alone when Marshall shut the courthouse door on the same family in 1813. Deeply researched, very readable, and the best book in print in which Duvall truly matters.
The reply brief in the funniest exchange in American legal scholarship. Currie's opening essay crowned Thomas Todd the most insignificant justice in history; Easterbrook, with perfect deadpan, presses the claims of Duvall — the longer tenure, the thinner output, the deaf decade. Beneath the joke is the serious point: opinion counts measure the Marshall Court's consensus system, not the man. And the metrics miss the one thing that doesn't fit them — the Hepburn dissent. Free online, and genuinely funny.
The standard reference account of the life: revolutionary clerkships, a musket at Brandywine, the Maryland offices, Congress, nine years as Comptroller of the Treasury, and the quiet decades on the bench. Dilliard mounts the classic defense — a man trusted with public office for sixty consecutive years cannot have been a nonentity.
The strangest endgame of any early justice: profoundly deaf, Duvall would not resign until he understood that Roger Taney, a fellow Marylander, would be nominated for his seat. The epilogue is exquisite — the Senate stalled Taney, Marshall died, Taney became Chief Justice instead, and the seat went to Philip Barbour. A short, sharp study of how justices time their exits, as alive a question now as in 1835.
The case that redeems the shelf, and it takes ten minutes to read. Mima Queen sued for freedom; Francis Scott Key argued her case; Marshall held the family's hearsay evidence — the only evidence such families could ever have — inadmissible. Duvall dissented alone: excluding it "cuts up by the roots all claims of the kind," and "the right to freedom is more important than the right of property." One paragraph, against his Chief, for a family his younger self had represented at the bar.
The institutional frame, as for Todd: the boardinghouse, the consensus norm, and the single opinion of the Court that swallowed individual voices. White explains how a justice could serve twenty-three years and leave roughly fifteen opinions — and why the rare dissent, like Duvall's in Hepburn, cost something real to cast. Oxford University Press.
The direct scholarly answer to the 'most insignificant justice' verdict elsewhere on this shelf — a full analysis of Duvall's lone dissent in the freedom suit Queen v. Hepburn ('the reason of slavery is against the right of freedom') and his opinion in Le Grand v. Darnall. The key Duvall study between Easterbrook's 1983 needle and Thomas's 2020 book.
The standard modern biographical encyclopedia of the Court: a signed essay on each of the 110 justices from Jay to Alito, alphabetically arranged, by a named scholar or journalist. Length tracks reputation — two pages for Thomas Johnson, three for Woods, eleven for Holmes — which is itself a rough map of who the literature has bothered with. It is not a substitute for a biography, and for the justices who have never had one it is often the most careful short account in print. Borrow it free at the Internet Archive.
The one-volume reference on the Court: more than a thousand signed entries on cases, doctrines, institutions and the justices, current to 2005. Cases and people share one alphabet, so a citation can be followed without changing volumes, and the biographical entries are short, written by specialists, and better than a longer sketch at carrying the historiography — what the argument about a justice currently is.

Ideas for Further Research
- The fair verdict, argued from the other corner than Todd's: Easterbrook's metrics capture the Marshall Court's consensus system, not the man — and they miss Queen v. Hepburn entirely. A justice's significance may hang on a single paragraph.
- The arc no novelist would risk: the young lawyer who won freedom for members of the Queen family in the 1790s became the justice who dissented alone for the same family in 1813 — while himself enslaving people at Marietta. The contradiction is the story.
- Duvall and Story were confirmed the same day (November 18, 1811) — the most lopsided pair of same-day appointments in the Court's history. He lived to ninety-one, reportedly the longest-lived justice until Oliver Wendell Holmes.
