Video assist predates Jerry Lewis 'patent'

A few weeks ago, I wrote about Jerry Lewis' role in the development of "video assist" technology, the use of video technology to support film making (see "Jerry Lewis and the elusive Video Assist patent"). Lewis was credited as the inventor of video assist during the Academy Awards telecast in February, and more specifically, was said to hold a patent on the technology.

I looked for this patent because I thought it would be interesting to write about it here, but I didn't find it. After I contacted the U.S. Patent and Trademark Office for help with the story, it looked too. The bottom line is that there is no such patent.

It turns out that video assist goes back to well before 1956, when Lewis claims to have invented it--as he did in a 2008 interview with Peter Bogdanovich.

Thanks to a commenter on my original post, plus some long discussions with Jim Songer, an engineer who made substantial contributions to video assist in the 1960s, I have tracked down what may be the earliest patents on video-assist technology.

But before I get into those patents, let me describe the elements of video assist technology in a little more detail.

First, video assist relates primarily to motion picture production. As the name suggests, the purpose of the video is to assist the production by allowing the director, actors, and other crew members to review what's being filmed. This can be done live, or if video recording is used, the video can be reviewed after the shot.

The ultimate implementation of video assist requires simultaneous film and video recording of the same scene with the greatest possible quality and convenience. Accordingly, both film and video recording should be accomplished with what amounts to one camera, which should meet all the other requirements for motion-picture principal photography, use the same viewfinder and all of the same controls, and work with the same lenses and lighting.

There can still be considerable value to a system that doesn't meet all these requirements. Indeed, the earliest video-assist systems were very simple.

Jerry Lewis and the elusive Video Assist patent

I have tremendous respect for Jerry Lewis. He's a great entertainer, a ferocious intellect, and perhaps the greatest charity fundraiser in history.

I was pleased to see Lewis receive the Jean Hersholt Humanitarian Award during the Academy Awards ceremony in February, principally for his work with the Muscular Dystrophy Association.

I had no idea that the annual Jerry Lewis MDA Labor Day Telethon had raised more than $2 billion over the years. There are larger charities, but I don't know any that owe so much to the fundraising efforts of one man.

The technical side of my brain was intrigued to hear that Lewis had received a patent for "video assist" technology--the use of closed-circuit television to allow a film director to review scenes as they're filmed.

It seemed to me the story of Lewis' invention of video assist technology would make a good post for Speeds & Feeds. I figured I'd also be able to mention another famous movie-star patent, Hedy Lamarr's 1942 patent (US 2,292,387) on frequency-hopping communications (as Hedy Kiesler Markey), and Walt Disney's 1940 patent on animation (US 2,201,689).

I ran a Google search for "'Jerry Lewis' patent" and found many references to such a patent, including an article by a Mark Adler of VAIdigital offering the title "Closed Circuit Television Applied to Motion Pictures." Adler said Lewis came up with the idea in 1956 and first used it in 1960 on his first film, "The Bellboy."

An article by Michael Frediani titled "On the Set with Video Assist" from an issue of The Operating Cameraman (then the magazine of what is now the Society of Camera Operators) includes a picture of a video assist system, complete with… Read more
