Where to Read the Transcript
The primary online source is Famous Trials, which hosts the digitized transcript prepared by PrintingHouse Press in New York City. The site’s index links directly to excerpts and summaries of individual testimony, so a reader looking for a specific witness does not have to page through the full PDF. A small number of pages missing from that primary file were located separately through the Federal Judicial Center and are linked individually on the same page.1Famous Trials.

What the Transcript Covers
The trial opened on March 6, 1951, in the U.S. District Court for the Southern District of New York before Judge Irving Kaufman. Jury selection was completed the following day, producing a panel of eleven men and one woman plus two alternates.5Clark County Bar. Five Things to Know About the Rosenberg Spy Case U.S. Attorney Irving Saypol led the prosecution, assisted by Roy Cohn. Emanuel Bloch headed the defense, joined by his father, Alexander Bloch.6Federal Judicial Center. The Rosenberg Trial
All three defendants were charged with conspiracy to transmit information about the atomic bomb and other national defense secrets to the Soviet Union in violation of the Espionage Act of 1917. The alleged conspiracy spanned June 1944 to June 1950. David Greenglass, Ethel’s brother, had already pleaded guilty and was severed from the trial to serve as the prosecution’s star witness. Anatoli Yakovlev, a Soviet consular official named in the indictment, was also severed from the proceedings.7FBI. The Atom Spy Case
The record moves through prosecution witnesses, defense witnesses including both Rosenbergs, summations, jury instructions, and the verdict. Physical exhibits are referenced throughout but not always reproduced. The cross-section sketch of the atomic bomb offered through David Greenglass, admitted as Government Exhibit 8, was impounded at the defense’s request on national security grounds, restricting access to the court, the jury, the defendants, and the attorneys.7FBI.

Key Testimony in the Record
The prosecution’s case rested on cooperating witnesses rather than extensive physical evidence, and the transcript preserves the direct examinations and cross-examinations that drove the verdict.
David and Ruth Greenglass
David Greenglass, a former Army machinist stationed at the Los Alamos laboratory during World War II, told the jury that Julius Rosenberg had recruited him into a Soviet spy ring in 1944 and that he had provided Julius with sketches and descriptions of high-explosive lens molds used in the atomic bomb, along with a cross-section sketch of the bomb itself. He also testified that Ethel Rosenberg had typed his handwritten notes on a portable typewriter at the Rosenberg apartment for transmission to Soviet contacts. Ruth Greenglass corroborated the account, telling the jury she had watched Ethel type the notes, and testified that the Rosenbergs had asked her in late 1944 to persuade David to steal classified information from Los Alamos.8Atomic Heritage Foundation. Rosenberg Trial
Ruth Greenglass was named as a co-conspirator but was never charged, an arrangement prosecutors used as leverage to secure the Greenglasses’ cooperation.6Federal Judicial Center. The Rosenberg Trial Years later, David Greenglass admitted his trial claim about Ethel typing the notes was false, telling journalist Sam Roberts, “I frankly think my wife did the typing, but I don’t remember.”8Atomic Heritage Foundation. Rosenberg Trial
Harry Gold and Elizabeth Bentley
Harry Gold, a Philadelphia chemist who served as a Soviet courier, testified that he collected espionage material from David Greenglass in June 1945, using a cut Jello box as a recognition signal and telling Greenglass that “Julius sent me.” Gold said he paid Greenglass $500 for the material.7FBI. The Atom Spy Case
Elizabeth Bentley, a self-described former Soviet operative, testified about phone calls she received from a man who identified himself as “Julius” between the fall of 1942 and November 1943. She served as an intermediary between this caller and her Soviet contact, Jacob Golos. Under cross-examination, Bentley admitted she had never met the caller in person and could not identify his voice as that of the defendant. Judge Kaufman overruled defense objections and told the jury it could assess the caller’s identity based on the totality of the evidence.9Famous Trials. Elizabeth Bentley Testimony
The Rosenbergs on the Stand
Both Julius and Ethel Rosenberg testified and denied every allegation of espionage. When asked about Communist Party membership, they invoked their Fifth Amendment right against self-incrimination in front of the jury, a decision legal analysts have since criticized.6Federal Judicial Center. The Rosenberg Trial On the question of a console table allegedly given to the Rosenbergs by Soviet contacts for microfilming documents, the prosecution could not produce the original and instead introduced a photograph of a similar piece of furniture as Government Exhibit 28. Julius testified he had bought the table at Macy’s for about $21.10Wikimedia Commons. U.S. vs. Julius and Ethel Rosenberg, Government Exhibit 28
Emanuel Bloch’s request during David Greenglass’s testimony that the courtroom be cleared and the atomic sketches impounded, while granted, has been widely regarded as a tactical error. Several jurors later recalled the moment as reinforcing the prosecution’s claim that the materials contained genuine atomic secrets.6Federal Judicial Center. The Rosenberg Trial
Verdict and Sentence as Recorded
After eight hours of deliberation, the jury returned guilty verdicts against all three defendants on March 29, 1951.6Federal Judicial Center. The Rosenberg Trial Judge Kaufman told the jurors, “My own opinion is that your verdict is a correct verdict.” On April 5, 1951, he sentenced Julius and Ethel Rosenberg to death. Morton Sobell received 30 years in prison, and David Greenglass later received 15 years for his cooperation. In his sentencing remarks, Kaufman called the crime “worse than murder” and blamed the Rosenbergs for casualties in the Korean War “exceeding 50,000 and who knows but that millions more of innocent people may pay the price of your treason.”11Monthly Review. Judge Irving Kaufman, the Liberal Establishment, and the Rosenberg Case The Rosenbergs were executed at Sing Sing Prison on June 19, 1953, the only Americans put to death by a civilian court for espionage during the Cold War.12Federal Judicial Center.

What the Transcript Does Not Show
Reading the trial record alone gives an incomplete picture. Materials that emerged later contradict or complicate key portions of the testimony it contains.
David Greenglass’s grand jury testimony from August 1950, released in 2015, directly contradicts what he said at trial. Before the grand jury he stated: “I said before, and say it again, honestly, this is a fact: I never spoke to my sister about this at all.” His grand jury account contained no mention of Ethel typing notes or operating a microfilm camera.13National Security Archive. Rosenberg Spy Case: Greenglass Grand Jury Testimony By March 1951 his story had changed, under a plea deal that shielded Ruth from prosecution. The defense never saw those grand jury pages during the trial; Roy Cohn was not obligated to turn them over because the Supreme Court’s decision in Brady v. Maryland, which requires disclosure of material favorable to the defense, was not issued until 1963.5Clark County Bar. Five Things to Know About the Rosenberg Spy Case Attorney David Vladeck has argued that prosecutors used Ethel as leverage against Julius, and that when the strategy failed to produce a confession the result was a miscarriage of justice.
Other conduct outside the transcript has been criticized. FBI Director J. Edgar Hoover had suggested to the Attorney General that charging Ethel could serve as a “lever” to force Julius to confess. During the trial, Saypol held a press conference announcing the perjury arrest of a witness connected to the defendants; Judge Thomas Swan of the Second Circuit later called the press conference “highly reprehensible,” though the appeals court denied relief because the defense had not moved for a mistrial. Although Kaufman publicly said he had not consulted the prosecution about sentencing, later disclosures showed he had privately solicited sentencing opinions from prosecutors, other judges, and Department of Justice officials before and during the trial.12Federal Judicial Center. The Rosenberg Trial
Post-Cold War intelligence disclosures have also reshaped the historical record. The Venona project, an American effort to decrypt Soviet intelligence communications, produced cables identifying Julius Rosenberg by the cover names “Antenna” and “Liberal,” and there is now broad scholarly consensus that he led an active espionage network. Ethel Rosenberg was never assigned a Soviet code name in the intercepted cables.14PBS. Venona: Decoding Soviet Espionage in America The Vassiliev notebooks, compiled from KGB archives smuggled out of Russia in the 1990s, added detail on the ring’s scope, identifying previously unknown agents and indicating that it had passed specifications for hundreds of weapons systems, including radar technology later used against American forces in Korea.15History News Network. Historians’ Muted Response to the Vassiliev Papers In 2008, Morton Sobell, then 91, publicly admitted for the first time that he and Julius Rosenberg had spied for the Soviet Union, though he characterized the information they passed as “trivial” and “negligible” and maintained the government had lied about them transmitting the secret of the atomic bomb.16New York Times. I Spy: A Belated Confession
In 2024 the National Security Agency declassified a memo written by codebreaker Meredith Gardner shortly after Ethel Rosenberg’s arrest in 1950. The memo states that while Ethel knew of her husband’s espionage, “due to illness she did not engage in the work herself,” describing her as a “party member” and “devoted wife” with no Soviet code name.17The Guardian. Ethel Rosenberg: Soviet Spy New Evidence The Rosenbergs’ sons, Robert and Michael Meeropol, have called the memo the “capstone” evidence proving their mother was not a spy and have requested a presidential proclamation declaring her wrongfully convicted and executed.18PBS NewsHour. Ethel Rosenberg’s Family Pushes Biden to Exonerate Her Historians remain divided; Mark Kramer of Harvard has said the conviction was “fully justified,” while Harvey Klehr of Emory University argues Ethel was an active participant. President Biden left office in January 2025 without acting on the request, and the Meeropol family has said they will continue their campaign.19WAMC. Shame on President Biden
Justice Felix Frankfurter later described the Supreme Court’s handling of the case as “one of the least edifying episodes in its modern history.” Read alongside the grand jury records and the intelligence files that have surfaced since, the trial transcript is both the foundational document of the case and, by itself, an incomplete one.
