# Mahlon Pitney *American lawyer, politician and associate justice of the Supreme Court of the United States (1858–1924)* Mahlon Pitney (born Mahlon R. Pitney IV; February 5, 1858 – December 9, 1924) was an American lawyer, politician and judge. He represented New Jersey for two terms in the [[United States House of Representatives]], from 1895 to 1899. From 1912 to 1922 he sat as an associate justice of the [[Supreme Court of the United States]].[^1] A New Jersey Republican, Pitney left the House for the New Jersey Senate, where he became Senate President. He then served on the New Jersey Supreme Court and as Chancellor of New Jersey before his federal appointment.[^2] On the Court he wrote the majority opinions in *Coppage v. Kansas*, *New York Central Railroad Co. v. White* and *Frank v. Mangum*.[^3] ## Early life and education Pitney was born in Morristown, New Jersey, to Henry Cooper Pitney and Sarah Louise (née Halsted).[^4] He studied at the College of New Jersey (now Princeton University), where Woodrow Wilson was a classmate and Pitney managed the campus baseball team. After graduating in 1879, he read law in his father's office.[^4] He was admitted to the bar in 1882 and opened a practice in Dover. For a period he practised there in partnership with his brother, John Oliver Halstead Pitney.[^4] Henry Pitney was appointed to a judgeship in 1889, and Mahlon Pitney went back to Morristown to run his father's firm. He married Florence Shelton in 1891, and the couple had three children.[^4] ## Political career ### Congress Pitney ran for the House in 1894 in New Jersey's 4th congressional district and unseated Johnston Cornish, who had served one term. He won a second term two years later.[^5] At the 1895 state Republican convention he served as chairman and backed John W. Griggs for the party's nomination for governor.[^5] ### State office Pitney hoped to become governor.[^5] He resigned from the House before his second term ended and was elected to the New Jersey Senate in 1898.[^5] There he served as the party's floor leader. After the 1900 election, the Republicans took control of the chamber, and Pitney later became Senate President.[^5] ## Judicial career Governor Foster M. Voorhees supported another candidate to succeed him. In 1901 he offered Pitney a seat on the New Jersey Supreme Court. The cited article describes the appointment as removing a political rival for Voorhees while keeping the party united.[^6] In 1908, seven years after joining that court, Pitney became Chancellor of New Jersey. The office was a judicial position peculiar to the state's 1844 constitution.[^6] ## Supreme Court of the United States On February 19, 1912, President [[William Howard Taft]] nominated Pitney to fill the associate justice seat of [[John Marshall Harlan]].[^7] The Senate confirmed him by a 50–26 vote on March 13, 1912, and he took the oath on March 18, 1912.[^7] Progressives opposed the nomination despite the margin of confirmation. Their opposition centred on his ruling as chancellor in *Jones Glass Co. v. Glass Bottle Blowers Association*, which restricted unions' ability to stop employers from bringing in strikebreakers.[^7] The cited article describes Pitney's reputation on the Court as relatively conservative and identifies him as an adherent of substantive due process.[^8] His majority opinion in *Coppage v. Kansas* held unconstitutional a Kansas statute that prohibited anti-union yellow-dog contracts. The Court stated that the police power could not legitimately be used to secure equal bargaining power.[^8] The same source describes him as distrustful of unions and also wary of the unchecked growth of business. It states that he favoured wider application of the Sherman Antitrust Act.[^8] In *New York Central Railroad Co. v. White*, Pitney's majority opinion sustained a New York workmen's compensation law. The cited article credits the decision with laying the foundation for the spread of such programs across the country.[^9] Pitney also wrote the majority opinion in *Frank v. Mangum*. That decision upheld Leo Frank's 1915 murder conviction in Atlanta, Georgia, which the cited article describes as wrongful. Justices Oliver Wendell Holmes and [[Charles Evans Hughes]] dissented.[^10] Pitney left the Court in 1922 after a stroke.[^11] The cited article also mentions [[Willis Van Devanter]] alongside Pitney, but the cached text is truncated, and the claim it makes about the two justices cannot be stated here.[^11] ## Death and legacy Pitney died in Washington, D.C., in 1924. He was buried at Evergreen Cemetery in Morristown, New Jersey.[^12] Richard Epstein was asked which twentieth-century justice had done most to protect core constitutional values. He named Pitney, calling him "a great justice" and "the only consistent near-libertarian on the Supreme Court."[^13] Pitney's daughter, Beatrice Pitney Lamb, wrote on political subjects. She was the grandmother of the actor Christopher Reeve, which made Pitney Reeve's great-grandfather.[^12] ## Notes [^1]: Wikipedia contributors, *Mahlon Pitney* (revision 1351785193, retrieved 2026-10-26) — lead section: birth and death dates, House service 1895–1899, Supreme Court service 1912–1922. https://en.wikipedia.org/wiki/Mahlon_Pitney [^2]: Wikipedia contributors, *Mahlon Pitney* (retrieved 2026-10-26) — "Political career" and "Judicial career" sections: New Jersey Senate, Senate President, New Jersey Supreme Court, chancellorship. https://en.wikipedia.org/wiki/Mahlon_Pitney [^3]: Wikipedia contributors, *Mahlon Pitney* (retrieved 2026-10-26) — "Supreme Court of the United States" section: majority opinions authored. https://en.wikipedia.org/wiki/Mahlon_Pitney [^4]: Wikipedia contributors, *Mahlon Pitney* (retrieved 2026-10-26) — "Early life and education" section: birth, parents, education, bar admission, practice, marriage. https://en.wikipedia.org/wiki/Mahlon_Pitney [^5]: Wikipedia contributors, *Mahlon Pitney* (retrieved 2026-10-26) — "Political career" section: 1894 and 1896 House elections, 1895 convention, 1898 state senate election, floor leadership, Senate presidency. https://en.wikipedia.org/wiki/Mahlon_Pitney [^6]: Wikipedia contributors, *Mahlon Pitney* (retrieved 2026-10-26) — "Judicial career" section: 1901 appointment by Voorhees, elevation to chancellor seven years later. https://en.wikipedia.org/wiki/Mahlon_Pitney [^7]: Wikipedia contributors, *Mahlon Pitney* (retrieved 2026-10-26) — "Supreme Court of the United States" section: nomination February 19, 1912; confirmation March 13, 1912, 50–26; oath March 18, 1912; progressive opposition. https://en.wikipedia.org/wiki/Mahlon_Pitney [^8]: Wikipedia contributors, *Mahlon Pitney* (retrieved 2026-10-26) — "Supreme Court of the United States" section: judicial philosophy, *Coppage v.
