Biography
Pedro Albizu Campos was a Puerto Rican lawyer, Harvard graduate, and from 1930 until his death the president of the Puerto Rican Nationalist Party. Across three separate imprisonments he spent approximately 26 years of his life in U.S. federal custody for his unrelenting campaign for Puerto Rican independence — making him the foundational figure that the entire later cluster of Puerto Rican political prisoners (the FALN era and the Macheteros era both included) traced their lineage back to.
In 1936, after two Nationalists assassinated Insular Police Chief Francis Riggs, federal authorities indicted Albizu Campos and other party leaders for seditious conspiracy; a first trial ended in a hung jury that voted 7–5 to acquit, but a second jury convicted them. He was held at the United States Penitentiary in Atlanta from 1937, released in 1943 to medical care in New York City, and not allowed to return to Puerto Rico until 1947. (The Ponce Massacre, in which Insular Police killed 19 unarmed Nationalists and bystanders, came during a march in March 1937 while he was imprisoned.) His health collapsed during this imprisonment, a pattern that would repeat.
In October 1950, days after the Jayuya Uprising and the attempt on President Truman's life by two Nationalists at Blair House, he was arrested again. He was convicted under Puerto Rico's notorious Ley de la Mordaza (Law 53, the 'Gag Law') of inciting violent revolt and sentenced to 80 years. Held at La Princesa Prison in San Juan, he and his supporters charged that he was being subjected to radiation experiments — a claim long dismissed by U.S. authorities and later substantially corroborated by independent medical examinations of the burns and lesions on his body. Governor Luis Muñoz Marín pardoned him in 1953 in deteriorating health, but the pardon was revoked in 1954 immediately after the Capitol attack carried out by his followers.
A pardon was issued again in November 1964 as he lay dying. He died in San Juan on April 21, 1965. He remains the central political figure in the Puerto Rican independence movement.
The editorial describes the nationalist leaders’ federal conviction and two-to-six-year sentences after a predominantly mainland jury replaced an earlier jury that had failed to convict. It reports Marcantonio’s work seeking a new trial or appeal. This is contemporary criticism of the existing prosecution, not an accomplished appeal decision or proof of sentence time served.

Governor Winship’s June 2, 1937 statement printed on page 14 gives the existing 1936 prosecution’s July 31, 1936 conviction, February 12, 1937 First Circuit affirmance and June 1, 1937 certiorari denial. It specifies six years on count 1, two years each on counts 2 and 3 suspended after service of count 1, and four years of probation. This replaces the imprecise six-to-ten-year sentence label with the stated sentence structure; it does not count ten years as actual service or use the still-future Atlanta transfer as an accomplished event. Winship’s polemical allegations about the Nationalist movement and his defense of the Ponce police are attributed official claims, not adopted as neutral findings.

Page 2's March 31 San Juan dispatch names Pedro Albizu Campos, Harvard graduate and leader of the Nationalist movement, among seven Nationalists facing federal indictments worded inciting insurrection and conspiring to overthrow the American government. District attorney Cecil Snyder said preliminary hearings would be dispensed with; a hearing was scheduled for April 2 and trial for June. Those were announced proceedings, not proof that either occurred or that a sentence had already been served. The six unnamed co-defendants are not invented as individual profiles.

Gerald Meyer’s 2010 Centro Journal study places this defendant among the eight Nationalists sentenced in the 1936 federal conspiracy prosecution. It reports the first jury deadlock on July 14, 1936, October denial of appeal bail and appellate affirmance on February 12, 1937, followed by transfer from San Juan municipal jail to Atlanta. It describes English-only correspondence and restricted family visits in the exile imprisonment. These collective procedural and conditions details do not establish a new arrest, individual gate-release date or completed sentence duration. Source: https://www.redalyc.org/pdf/377/37722223004.pdf#page=9 Page 17 dates the Atlanta probation release to July 3, 1943 and describes a subsequent two-year stay at Columbus Hospital with parole prohibiting return to Puerto Rico. Its July 3 release date is a secondary-source assertion for reconciliation with existing records.
The chronology credited to Benjamín Torres and Rosa Meneses Albizu names this defendant among the eight Nationalists tried in 1936. It identifies Robert Cooper as presiding judge and A. Cecil Snyder, Marcelino Romaní, Jorge Ortiz Toro, James E. Ruffin and Amos W. W. Woodcock as prosecutors. It distinguishes a first jury that could not agree from a second trial that returned a guilty verdict. The chronology also records the eight prisoners’ transfer to the Atlanta penitentiary on June 7, 1937; that is a transfer within the already recorded imprisonment, not a new first-admission date. The case field incorrectly labeled this prosecution an acquittal, despite the second-trial conviction already described in the biography; it is corrected to convicted. The chronology places his departure from prison for Columbus Hospital on June 3, 1943. That hospital transition is preserved as narrative rather than an assumed end of all custodial restraint. Its September 30, 1953 pardon date is not substituted for the existing physical-release date, and no confinement total is recalculated.
The page 7 San Juan brief identifies Pedro Albizu Campos and seven other Nationalists and reports Federal Judge Robert A. Cooper denying bail pending appeal of their conspiracy convictions. Page 5 reports Roger Baldwin returning to New York with the trial record to prepare an appeal to the First Circuit in Boston and the ACLU planning a renewed bail request. That article prints Jose Albizu Campos, but the same issue’s correct full name, seven co-defendants, conviction and bail context identify Pedro; the first-name discrepancy is preserved rather than creating a second person. An intended appeal or renewed bail motion is not evidence of success or release.
The ACLU appealed to Secretary Ickes to dismiss the sedition prosecutions against Campos and other Nationalist leaders, arguing that a murder-related allegation should not become sedition. The report announces July 14 as the expected trial date; it does not establish an acquittal, dismissal, conviction or actual custody endpoint.

Page 5 reports a march of more than ten thousand Puerto Ricans through lower Harlem and quotes Congressman Vito Marcantonio condemning the imprisonment of Albizu Campos and other independence leaders. This is a specific contemporary defense demonstration and attributed political criticism, without new custody endpoints or a completed release.
Dávila Marichal records Albizu Campos’s transfer to La Princesa on November 14, 1950, and confinement in isolation. On May 18, 1951 he was moved to a better cell. These are internal custody conditions and transfers, without a new admission or release endpoint.

The Cuban committee’s April 12, 1939 manifesto individually lists him as actually confined at Atlanta. This is contemporary prison-location evidence, not an admission date, a completed sentence or a new arrest. The pamphlet was published in December 1939 and reprints documents of several different dates. The August30 appeal names the three as editors of La Nación Puertorriqueña, La Palabra and Armas respectively. The February27 DOJ reply (PDF48) only promises consideration if an executive-clemency application is made; it grants no pardon or release.
