## Early life, education, and family

John F. Davis was born on July 11, 1907, in Portland, Maine. His parents were Marshall Davis and Marguerite Gifford. He attended the public schools in Portland, graduating from high school in 1924.
He attended Bates College, graduating in 1928 Phi Beta Kappa, and Harvard Law School, from which he obtained his law degree in 1932. He worked on the Harvard Law Review.

## Career

Davis's first job was with Robb, Clark, and Bennet in New York City.

### Civil service

In 1933, Davis became a government attorney at the United States Department of the Interior. In 1936, he briefly worked for a U.S. Senate committee investigating railroad finance, then moved to the Securities and Exchange Commission (SEC). During World War II, he worked as counsel for the United States Coast Guard.

### Private law practice

In 1947, Davis returned to private practice in Washington, DC. By 1948, he had become one of four partners in the law firm of Hilmer & Davis at 1700 I Street NW.

### Hiss case

Davis is best remembered as one of the defense attorneys who represented accused Soviet espionage agent Alger Hiss before the House Committee on Un-American Activities in 1948 and at Hiss's two 1949–50 trials for perjury in the Southern District of New York.
On August 25, 1948, Davis first appeared as counsel to Hiss on "Confrontation Day", when Hiss and Whittaker Chambers (who, under subpoena, had testified about Soviet underground networks he had run in Washington in the 1930s, including the Ware Group, of which Hiss was a member). In September 1948, he worked with William L. Marbury, Jr. After the U.S. Department of Justice indicted Hiss on two counts of perjury, Davis served on his defense team under Edward Cochrane McLean.
After Hiss's conviction in January 1950, although Hiss worked for the rest of his life to prove his innocence, Davis (like Marbury and McLean) did not partake in those efforts.
In 1974, Allen Weinstein interviewed Davis for his book Perjury: The Hiss-Chambers Case. According to Weinstein, Davis said that Hiss had contacted him in December 1948 about an "old typewriter" turned out to be the Woodstock typewriter used for scores of stolen documents that formed evidence during the two trials of Hiss in 1949. Davis also recommended that the Hiss defense team build an identical typewriter to prove "forgery by typewriter", but experts were unable to do so.

### Civil service again

During the 1950s, Davis served as an assistant Solicitor General in the U.S. Department of Justice. He argued more than 50 cases before the U.S. Supreme Court. These included a government antitrust case against the DuPont Company, which forced it to divest from General Motors Corporation of $2.5 Billion or 23% of GM stock.
In 1961, Davis was appointed Clerk of the Supreme Court under Chief Justice Earl Warren, succeeding James R. Browning, who had been appointed to a federal judgeship by President Kennedy. As Clerk, Davis was responsible for maintaining the Court's docket and files. He also administered the oath of office to several new Justices, including Thurgood Marshall, the Court's first African American member, and Chief Justice Warren E. Burger.
Davis served as Clerk of the Supreme Court until 1970, when he returned to private practice in Washington, also serving during the 1970s as a Special Master for the Supreme Court in two cases within the Court's original jurisdiction and co-authoring a law review article on the precedential effect of Supreme Court opinions approved by only a plurality (as opposed to a majority) of the Justices.

### Law School

Davis also taught during the 1970s as a law professor at Georgetown University and later at the University of Maryland School of Law. He retired from the latter position in 1988.

Lawyer, professor, and biographer G. Edward White is a son-in-law.

## Legacy

A portrait of Davis hangs in the Supreme Court.
Davis believed that Hiss was innocent of espionage.
In a 2004 memoir, Garry Wills noted that Hiss lied about not taking counsel to his first HUAC hearing on August 5, 1948: Hiss took Davis.
