Who builds and sets up the presidential lecterns?

 


 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

I saw an AP article by Zeke Miller and Colleen Long from October 11, 2022 titled Give him a hand: Biden ditching lectern for handheld mics. It mentioned that the type of large, bullet-resistant lectern shown above is known as a Blue Goose, and its smaller brother is a Falcon. An article by Josh King at The Verge on January 25, 2017 titled Trump’s big league microphone described the switch to a single close-in gooseneck microphone replacing the former pair of Shure SM 57s. That article described how the audio and other setups are carried out by a military unit (mostly of non-commissioned officers [NCOs]) known as the White House Communications Agency (WHCA).

 

Another article by Jacqueline Harnes at the U.S. Army on January 26, 2011 describes how the President is Wired for Sound. Still another article by Michael L. Lewis at the NCO Journal on April 21, 2015 titled NCOs Integral to Enabling the President to Communicate Anytime, Anywhere notes that:

 

“Service members at WHCA build every presidential podium, outfit and man every motorcade communications vehicle, operate the president’s TelePrompTer, and transport the necessary equipment wherever it is needed worldwide.”

  

Paul Simon even mentioned the presidential lectern or podium in a verse of his 1973 song, Loves Me Like a Rock:

 

“…. If I was President

And the Congress called my name

I’d say ‘now who do…

Who do you think you’re fooling?’

 

I’ve got the presidential seal

I’m up on the presidential podium

My mama loves me, she loves me

She get down on her knees and hug me

And she loves me like a rock….”

 

There is a good article about using microphones by Brian Young on pages 14 and 15 of the July 2015 Toastmaster magazine titled The Power of Sound. There also is a 5 – 1/2 minute YouTube video titled Toastmasters Tips -The Proper Way to Use a Microphone.

Rick Santorum’s Teleprompter Tantrum























Last week he complained childishly that the rules should be changed to favor spontaneity:

“See, I’ve always believed that when you run for president of the United States, it should be illegal to read off a teleprompter, because all you’re doing is reading someone else’s words to people.”

Teleprompters are older than Mr. Santorum. Their first political use was sixty years ago - by Herbert Hoover at the 1952 Republican Convention. (If you’d like to see how they once looked, search on Google Books for an article about “How a Teleprompter Works” in the July 1960 issue of Popular Science magazine on pages 104 and 105).

In the March 14th episode of his comedy satire TV show The Colbert Report (5 minutes from the beginning) Stephen Colbert took Santorum’s complaint to an absurd conclusion:

“Now, Rick Santorum is resonating with voters because of his authenticity. He always speaks off the cuff, which is why his sweaters don’t have sleeves. And Santorum believes authenticity should be legally mandated. [plays video clip of Santorum’s statement].

Yes, it should be illegal. Voters cannot trust candidates who have somebody else’s words in their mouths. That’s why no ventriloquist’s dummy has been nominated since the dark days of Charlie McCarthyism.

But we cannot, I believe we cannot, stop at teleprompters. I reject all pre-wrtitten words.That’s why I’m against reading books. I mean, books are a lie. When I read the words it makes thought sounds in my head like I’m thinking them.”  


Mr. Santorum would like us to return to a simpler time, but how far back would that be? I looked up what the first Catholic presidential nominee, Alfred E. Smith, had to say about public speaking in the really old days. Mr Smith was a former governor of New York who ran as a Democrat in the 1928 election. In a May 24, 1930 Saturday Evening Post article on "Spellbinding" he talked about unamplified speeches lit only by kerosene torches:

“...outdoor speaking in those days required a man to be in vigorous health and to have a good voice, or else he lasted only about five minutes on the platform, when the patience of the listening mob would be completely exhausted, and they usually started crying out for somebody else and kept up until they got him.

Nevertheless, it was a great training school for young men. It may have had its faults. It may have been crude, but it certainly was not without virtue. To my own knowledge, many young men who distinguished themselves in their later years began their early campaign speaking in the open air. The one great thing about it was that the young man starting out did not feel that he had to be an orator. There is quite a difference between coming out in front of the footlights and climbing upon the back of a truck. Maybe it is the possession of the knowledge that the truck affords a quicker get-away if you are not making a hit.”  
 

Mr. Smith lost the 1928 presidential election by a landslide - to the Republican candidate, Herbert Hoover.

Would you rather be heard, or be able to read your notes?


















That’s not a pleasant choice! Please check out the whole room setup before you speak - including both sound and lights.

If the light on that lectern needs to be on for your speech, then check to see it doesn’t generate a buzz that interferes with the microphone. Things might have been fine until when the incandescent lamp burned out, and it got replaced by a compact fluorescent bulb, as was discussed by a 2007 article in EDN magazine.

Images from the History of Medicine showed Margo Heygood speaking at the 1976 NIH Conference on DNA.

Public address systems and the demise of theatrical gestures













On page 14 of his book Working the Room, Nick Morgan notes that:

“These gestures were important because of how speeches were delivered until the advent of radio and television in the mid-twentieth century. It’s important to remember that public speaking was a form of mass entertainment. Most speeches were delivered without amplification to audiences in large halls or outdoors. As a result, a style of speaking developed that involved grand rhetoric, big, dramatic gestures, and voice projection.”

In a blog post on June 8 Jim Anderson described how the introduction of public address systems early in the twentieth century led to the demise of wildly theatrical hand gestures. Once everyone in a large audience could hear clearly, there was no longer a necessity for gestures as a backup form of communication to those far away from the speaker.

Triode vacuum tubes (or thermionic valves) were patented in 1908. They were a key component for audio amplifiers. By 1922 there was a public address system in the US Capitol. A red-tinted photo of the control room is shown above, as is a pole-mounted horn loudspeaker from 1923.

A web page for the Museum of Public Address has many more photographs of early equipment. I was surprised to read that back on December 30, 1915 a Magnavox public address system was used at the Civic Auditorium in San Francisco for a remote wire broadcast by the California governor, Hiram Johnson. The governor had a severe cold, and spoke from his home. This predated commercial radio, which began in Pittsburgh on November 2, 1920 when KDKA broadcast election returns. Manufacture of radio receivers led to the mass production of loudspeakers.

In the late 1920s and early 1930s most movie theaters in the US were being equipped for sound films, and thus large amplifiers suitable for public address systems were mass produced.

An unusual sound system disaster



















Is there anything worse than having a sound system with a dead microphone? There is, and I encountered it last year. For a while it seemed like my talk was going down in flames.


In January 2008 I gave a technical talk. It was for a corrosion meeting held at the ski resort in Sun Valley, Idaho. There were presentations in one half of the Inn ballroom all day Thursday. The wireless microphone, sound system, the laptop computer, and digital projector all worked perfectly.


My talk was the second one on Friday morning. Our chairman handed me the microphone. Just as I was about to begin speaking, we all heard another voice take over the sound system. He began with, “Welcome to the annual refinery meeting!” My microphone acted like it was turned off, and the other speaker continued by reciting their safety record. Then he began discussing production statistics.


Our chairman sent someone running down the hall for the audio-visual staff. They got our sound back after three or four minutes, but it seemed like forever to me. What could have gone wrong only on the second day?


The large ballroom had been split by a movable wall to accommodate two different meetings. On Thursday no one was using the other half of the ballroom, so their wireless microphone had been switched off. The staff had forgotten to split the sound system into two independent parts. On Friday the other half of the room started their meeting later than we did. As soon as their master wireless microphone was switched on it overrode ours, and it fed the speakers for the entire room.


Fortunately this is an uncommon situation. Unfortunately, unless you are a skilled mime, there is not much you can do about it.


It is more common to encounter an adjacent ballroom with amplified music. An accountant told me about a tax refresher course held next to a Native American Powwow. Their speaker could not compete with drums and chants. Bagpipes also are rather piercing.


In a previous post I mentioned having a projector bulb fail as I began a long technical talk. With more forethought I could have begun without using visual aids. You can too, if you have planned, written out, and outlined your introduction.
