In 1952, the Republican National Convention and the Democratic National Convention were both held at the International Amphitheatre in Chicago, Illinois during separate weeks of July. The Republicans met July 7–11, while the Democrats met July 21–26.

The conventions were the first United States presidential nominating conventions to be televised in real-time nationwide. The Democrats adapted their convention last-minute to eliminate several aspects that had come across unflattering for Republicans during their convention. Among advents introduced due to television was the Democrats' debuting a concealed speech teleprompter. The International Amphitheatre was the site of the conventions instead of the even-larger Chicago Stadium arena (the site of the several most recent conventions previously held in the city) due to the assessment of party leaders that it was more suited for television broadcasting. A major undertaking in preparation for the convention was the installation of an expensive and powerful air conditioning system at the International Amphitheatre, making the 1952 conventions the first major party presidential nominating conventions to be held inside of an air conditioned venue.

Other important aspects of the conventions' logistics included arrangement of overnight hotel accommodations, transportation, finances, and entertainment for conventiongoers; as well as security.

Site selection

Overview of bids Six cities formally submitted bids (Chicago, Illinois; Kansas City, Missouri; Miami, Florida; Philadelphia, Pennsylvania; Los Angeles, California; and San Francisco, California). Initially, Atlantic City, New Jersey and Detroit, Michigan had indicated their interest in hosting, but both abandoned their efforts without submitting a formal bid. Kansas City and Miami only sought to host the Democratic convention, while the four other cities indicated their interest in hosting either or both conventions. Chicago and Philadelphia were the finalist bid cities, with Chicago being selected by both parties.

Scheduling On May 10, 1951 , the seven-member subcommittee of the Republican Party unanimously voted not only to recommend Chicago be selected as the site of convention, but to also recommend that the convention be held on July 21. This was later into the year than the party had ever held a presidential convention, and was seen as likely to face opposition from Republican National Committee members. The subcommittee justified its recommendation of a July date by arguing that the convention should be held after Indiana’s state Republican convention, which was scheduled to commence on June 28. In a compromise two days later, the Republican National Committee voted 88–11 to approve holding the convention on the week of July 7. The July date was the latest that Republicans had ever held their convention. In their previous history, all but two of their previous conventions had been held in June.

At the time, it was typical that Democrats held their convention after the Republicans at a later date than the Republicans. From 1864 through 1952, the Democratic Party had held its convention at a later date than the Republicans in every election except 1888. Republicans had hoped to usurp this norm. By scheduling their convention much later than normal, they had hoped that they might force Democrats to hold their own convention previous to the Republicans. However, Democrats ultimately refused this pressure, and instead scheduled their convention late as well. The Democrats opted to schedule their convention for the week of July 21, two weeks after the Republican convention.

The Republicans were still working on finalizing timetables for the convention proceedings mere days prior to the convention's opening.

Television broadcasting

The conventions were the first political conventions to be televised live, coast-to-coast. Previously, since 1924, the primary means which Americans received gavel-to-gavel rolling coverage of presidential nominating conventions had been broadcast radio.

Historian Florencia Pierri observed in 2020,

The main venue for the conventions was moved from the Chicago Stadium arena (where the most recent previous conventions in Chicago had been staged) to the International Amphitheatre upon the judgement of party leaders that the latter was a better-suited venue for television broadcasts. Convention planners were anticipated to schedule more-important events during the evening so that a larger television audience would be viewing live coverage.

The impact of the Republican Convention television broadcasts was an immediate one. After carefully watching the Republican Convention, the Democratic Party made last-minute alterations to their convention held in the same venue to make their broadcast more appealing to television audiences. They constructed a tower in the center of the convention hall to allow for a better shot of the podium, and Democrats exercised more control over camera shots and the conduct of delegates in front of the cameras. While Republican speakers had used a teleprompter that was often visible to television audiences, Democratic speakers were given a teleprompter that was hidden into their lectern. Ahead of the start of their convention, Democrats promised that (based on lessons learned from observing the Republican convention) they would start all sessions within fifteen minutes of their scheduled opening times, and grant a television camera to be set up in a position that would allow a head-on view of the speaker's platform (which was not available to broadcasters during the Republican convention).

Radio broadcasting

Edward R. Murrow provided news reports for the CBS Radio Network. Russ Van Dyke of CBS' Iowa affiliate KRNT also provided reporting from the convention.

Voice of America (VOA), an international radio network funded by the U.S. Department of State, broadcast coverage of convention across the globe. VOA produced broadcasts in 46 different languages, concentrating on those spoken in Iron Curtain nations. VOA's facility at convention was a small recording booth. Dedicated telephone lines relayed what was produced in this booth to VOA's broadcasting headquarters in New York City. VOA would have reporters record content in that both each day in a variety of languages, reporting the stories of interest. Each of its reporters recorded two stories every day of the conventions, which were then transmitted to New York City. Editing work was done in New York City before these stories were broadcast by VOA. The Soviets' own media broadcast radio stories on the convention, portraying the nomination process as being shaped by a "small circle of bosses", with Radio Moscow, referring to American elections as the "false American democracy".

Telecommunications

An extensive telecommunications infrastructure needed to be established in order to accommodate not only the press (print press, television, and radio), but also to facilitate communications involving delegates and party leaders amid vote-wrangling for platform votes and nomination balloting. Tens of thousands of incoming calls related to the convention were received at the hotels were delegates were housed.

More than 100 public telephones were added to the International Amphitheatre for the conventions. Included in this, the Illinois Bell Telephone Company set up a telephone message center for use by delegates, which also featured walkie-talkie service for use in emergencies.

During both conventions the Conrad Hilton (today known as the Hilton Chicago) received busy telephone traffic, due to its use as both the convention and media headquarters, as well as the location of hotel accommodations for many delegates and reporters. It was reported that during the Republican convention, its telephone switchboards received more traffic than it ever had before; peaking with traffic as high as 4,000 calls in a single hour. In anticipation of the increase in calls being placed from the hotel from during the convention, additional phone booths had been installed for outgoing calls to be made from.

Convention leadership Charles Hacker served as the Republican convention's chief sergeant-at-arms. Robert A. Taft held sway over arrangements committee for the Republican convention, as evidenced by the arrangement committee's selection of Douglas MacArthur for the convention's keynote speaker (something which Taft's camp preferred). Congressman Joseph W. Martin Jr. served as permanent chairman of the Republican convention.

Jacob M. Arvey served as chairman of the Democratic convention host committee. Neal Roach served as the pre-convention manager overseeing Democratic convention preparations. At the time of the convention, Frank E. McKinney was chairman of the Democratic National Committee and Lawrence Westbrook was assistant chairman. Leslie L. Biffle (the secretary of the United States Senate) served as the convention's sergeant-at-arms.

Preparation of the International Amphitheatre

Venue specs The most recent presidential conventions in Chicago had been held at the Chicago Stadium arena. However, with the new advent of television broadcasting, it was decided to hold the 1952 conventions at the International Amphitheatre arena. While the venue was smaller in capacity than the Chicago Stadium, the leaders of the parties believed that it was better suited for television broadcasting. While it had a lower capacity than the Chicago Stadium, the 12,000 seat capacity International Amphitheatre was still among the world's largest-capacity arenas. It sat 4,500 attendees on the arena floor, and 7,500 in its mezzanine and balcony seats. It had dining facilities that could feed 3,000 individuals simultaneously. The arena portion of the building was by and had a ceiling that rose above the arena floor.

The International Amphitheatre stood (by different measures) or southwest of the Chicago Loop (the central business district of Chicago). It was located at the gateway of the Union Stock Yards, at the time that largest stockyard in the world. The arena was owned by the Union Stockyard and Transit Company, who also owned the stockyards. It was expected that the stockyards would be toured by some of the delegates during their convention visit to Chicago.

The venue featured an organ, which was utilized at times during the conventions to provide music.
