Sidney Hillman

Sidney Hillman moved between two centers of wartime power: the federal administration of industrial production and the labor movement’s influence over Democratic Party politics. As co-director of the Office of Production Management, he was a target of Harry S. Truman’s Senate committee, which faulted the agency’s divided leadership and challenged Hillman’s handling of a defense contract. By 1944, however, he was directing the CIO’s Political Action Committee and had become an important participant in the contest over the party’s vice-presidential nominee.

Labor Origins and Political Position

Hillman’s career began far from the political hotels and private meetings of the national convention. Born in Lithuania and educated to be a rabbi, he became an eight-dollar-a-week apprentice pants cutter in New York’s garment district. He led his first strike at twenty-three and had founded the Amalgamated Clothing Workers of America by the time he was thirty. He had also joined the Socialist Party and retained a slight accent. The account emphasizes how that background could make him appear a dangerous radical in places such as Grandview, Missouri, even as he became a consequential national figure.

By the 1944 convention, Hillman directed the CIO’s well-funded Political Action Committee, a new force in American politics. His labor credentials gave him influence that party organizers could not simply dismiss, but they also marked him as an outsider to the party establishment. He was not even a registered Democrat. To party chiefs Bob Hannegan and Mayor Kelly, he seemed an amateur and therefore not wholly trustworthy, notwithstanding his PAC’s resources and his allegiance to Franklin D. Roosevelt. His position was consequently unusual: he had access to the President’s political circle, yet the Democratic organizers did not regard him as one of their own.

Conflict over Wartime Production

Hillman’s administrative career placed him at the center of a dispute over how the United States should organize its defense production. Franklin D. Roosevelt had created the Office of Production Management with two heads: Hillman, a labor leader, and William S. Knudsen, formerly of General Motors. Roosevelt wanted authority divided between them. Truman’s committee concluded instead that the arrangement contributed to delay and confusion, and that the country needed a single production chief with clear authority.

Truman’s criticism of Hillman was pointed. He was outraged when Hillman withheld a construction contract from a low bidder because he feared trouble from what he called “irresponsible” elements in the American Federation of Labor. On October 29, 1941, Truman told the Senate that the United States should not fear trouble from any source and said Hillman should be replaced if he could not or would not protect the country’s interests. The committee’s assessment extended beyond that particular decision: it described the Office of Production Management’s leadership as inept and its record as marked by failures both to act and to confront problems.

The committee also argued that the agency should dispense with its dollar-a-year officials. It objected to corporate executives holding government roles while retaining business ties, warning that divided loyalties could encourage decisions favorable to their companies. That criticism formed part of the wider indictment of the production agency in which Hillman had served as co-director; it was not simply a dispute about his labor affiliations. The committee’s scrutiny helped bring about his removal from the Office of Production Management. In the convention account, this history explains why Hillman had little reason to expect cooperation from Truman when they met again in 1944.

The 1944 Nomination Struggle

The political importance of Hillman’s position was signaled even before his meeting with Truman. On July 15, 1944, Franklin D. Roosevelt’s train stopped in Chicago, Illinois, so Bob Hannegan could speak privately with the President. Roosevelt told Hannegan that whatever was decided about the vice-presidential nomination, he must “Clear it with Sidney.” The instruction referred to Hillman’s authority at the head of the CIO’s Political Action Committee and made clear that his approval mattered to the President’s political calculations.

A few days later, Truman met Hillman over breakfast in Hillman’s suite at the Ambassador East. Truman asked for his support for James Byrnes. Hillman declined: he was working for Henry Wallace, he said, and if Wallace could not be nominated, he preferred either William O. Douglas or Truman. He considered a Byrnes nomination a mistake. The exchange brought together their earlier institutional conflict and their new political roles. The senator whose committee had helped remove Hillman from the production agency now sought his backing; Hillman, despite that history, spoke directly against Truman’s preferred candidate.

Hillman’s refusal was part of a broader opposition to Byrnes, not an isolated veto. When Ed Flynn convened party leaders in a private Chicago apartment, he argued that Truman was the candidate already agreed upon with the President. Hillman said Byrnes was unacceptable to organized labor. Flynn added that Byrnes could cost the Democrats at least 200,000 Black votes in New York alone and called him a political liability. Hannegan, Flynn, Ed Pauley, Frank Walker, Allen, Kelly, and Hillman joined the group that reporters called the “Harmony Boys.” Flynn contacted Roosevelt in San Diego; after the men spoke with him, the President agreed that Truman should be the nominee.

Narrative Role and Significance

Hillman’s place in the account rests on the contrast between two kinds of influence. In the production agency, he shared formal authority with Knudsen, but Truman’s committee treated divided command as a structural failure and challenged Hillman’s specific judgment about labor opposition. In party politics, Hillman had no formal nomination power, yet Roosevelt’s instruction to consult him and his participation in the decisive meeting show that the labor movement’s support had become politically consequential.

His role also complicates a simple account of Truman’s rise. The committee’s attack on Hillman belongs to the story of wartime oversight and production reform; the convention places the two men on the same side of the eventual choice, though not at first on the same candidate. Hillman’s support for Wallace, his rejection of Byrnes, and his eventual alignment with the group pressing for Truman reveal a political calculation shaped by labor’s interests and the threat Byrnes posed to the Democratic coalition. The episode presents Hillman as both a contentious administrator and a necessary political interlocutor: a figure the party establishment distrusted, but whose constituency and organizational reach it could not afford to ignore.
