John Weld Peck (February 5, 1874 – August 10, 1937) was a United States district judge of the United States District Court for the Southern District of Ohio.
Born in Wyoming, Ohio, Peck received an Artium Baccalaureus degree from Harvard University in 1896 and a Bachelor of Laws from the University of Cincinnati College of Law in 1898. He was in private practice in Cincinnati, Ohio from 1898 to 1919.
On October 30, 1919, Peck was nominated by President Woodrow Wilson to a seat on the United States District Court for the Southern District of Ohio vacated by Judge Howard Clark Hollister. Peck was confirmed by the United States Senate on November 5, 1919, and received his commission the same day. Peck served in that capacity until April 3, 1923, when he resigned.
After his resignation from the federal bench, Peck returned to private practice in Cincinnati until his death on August 10, 1937.
Peck was the uncle and namesake of John Weld Peck II, also a United States federal judge.[1]
