As I attempt to compose this post, my close friend and I have 6 various displays connected to 3 kinds of tools. We’re operating in the exact same space however on our very own jobs– different yet with each other, a comfy friendship.
I had actually never ever actually considered the spreading of displays as a peacekeeping device till I came across among Allen B. DuMont’s 1950s dual-screen television. DuMont’s concept was to allow 2 individuals in the exact same space view various programs. It advised me of my very early childhood years and my household’s one television set, and the countless debates with my sis and moms and dads over what to view. Daddy constantly won, and his selection was seldom mine.
The DuMont Duoscopic Was 2 Televisions in 1
Allen B. DuMont was a leader of industrial tv in the USA. His eponymous firm produced cathode ray tube and in 1938 presented among the earliest digital television set. He recognized exactly how humanity and a scarcity of television displays might separate pairs, brother or sisters, and good friends. As necessary, he developed a minimum of 2 model Televisions that might play 2 programs at the same time.
In the 1945 model revealed at leading, DuMont retrofitted a maple-finished closet that initially held a solitary 15-inch Plymouth television receiver to house 2 black-and-white 12-inch receivers. Different sound might be had fun with or without earpieces. Customers made use of a 10-turn dial to tune right into television network 1 (which went off the air in 1948) and VHF networks 2 via 13. As radio was still a lot more preferred than tv, the dial additionally consisted of FM from 88 to 108 megahertz, plus a couple of networks made use of for weather condition and aeronautics. The reduced left cabinet held a phonograph. It was an all-in-one amusement facility.

In 1954, DuMont presented a various method. With the DuMont Duoscopic, 2 various networks were transmitted on a solitary display. To the nude eye, the photos showed up laid over on each other. However a customer that used polarized glasses or checked out the display via a polarized panel saw simply among the photos.
Duoscopic visitors might utilize an earpiece to pay attention to the sound of their selection. You might additionally utilize the television set to view a solitary program by choosing just one network and playing the sound via one audio speaker.
DuMont appeared dedicated to the concept that relative ought to hang around with each other, also if they were participated in various tasks. A photo of the Duoscopic sent by the Associated Press Wirephoto Solution declared “Say goodbye to lonesome evenings for the missus.” According to the inscription, she might sign up with “Husband,” that was currently unwinding in his comfortable elbow chair appreciating his preferred program, and now view something of her very own deciding on.
” Would certainly you think it?” a Duoscopic brochure asks. “While HE sees and listens to the battles, SHE sees and hears her play … Different watching and solo audio permits your household an option.”
The modern technology to divide and separate the photos and sound was crucial. The Duoscopic had 2 CRTs, each with its very own feed, evaluated appropriate angles per various other. A half-silvered mirror laid over both photos onto a solitary display, which might after that be filteringed system with polarized glasses or displays.

A different box might be easily put neighboring to manage the quantity of each program. Individuals might toggle in between both programs with the flick of a button. Each collection included 8 earpieces with lengthy cables. A brief note in the March 1954 concern of Electric Design commends the designers that crafted the stereo to get rid of audio hemorrhage from the audio speakers. It keeps in mind that a customer “extremely quickly might view one tv program and pay attention to the audio material of a 2nd.”
Or, as a United Press item released in the Panama City Information Herald recommended, component of the household might utilize the earpieces to view and pay attention to the television while others in the space might “check out, play bridge, or simply rest and brood.” I believe the brooders were the youngsters that still really did not reach view their preferred program.
Naturally, selection was a loved one issue. In the 1950s, lots of united state tv markets were fortunate to have also 2 networks. Just in significant cities existed even more shows alternatives.
The just recognized instance of DuMont’s side-by-side variation stays at the South Carolina State Museum, in Columbia. However resources suggest that DuMont prepared to make regarding 30 Duoscopics for demo functions, although it’s uncertain the number of were in fact made. (The Smithsonian’s National Gallery of American Background has a Duoscopic in its collections.) Sadly, neither variation ever before entered into mainstream manufacturing. Possibly that’s since the business economics really did not make good sense: Also in the very early 1950s, it would certainly have been less complicated and more affordable for family members to merely acquire 2 television and view them in various spaces.
That Was Very Early Television Leader Allen DuMont?
DuMont is a fascinating number in the background of tv since he was proactively participated in the complete range of the market. Not just did he create and make receivers, he additionally carried out broadcasting experiments, published papers on transmission and function, ran a tv network, and generated shows.
After finishing from Rensselaer Polytechnic Institute in 1924 with a level in electric design, DuMont operated in a plant that produced vacuum cleaner tubes. 4 years later on, he signed up with the De Woodland Radio Co. as primary designer. With Lee de Forest, DuMont aided develop a speculative mechanical television terminal, however he was unsure by the modern technology and promoted for all-electric television for its crisper photo.
When the Radio Firm of America obtained De Woodland Radio in 1931, DuMont began his very own research laboratory in his cellar, where he dealt with enhancing cathode ray tubes. In 1932 he designed the “magic eye,” a vacuum cleaner tube that was an aesthetic adjusting help in radio receivers. He marketed the legal rights to RCA.
In 1935, DuMont relocated the procedure to a previous pickle manufacturing facility in Passaic, N.J., and included it as the Allen B. DuMont Laboratories. The firm generated cathode ray oscilloscopes, which aided fund his explores tv. He debuted the all-electronic DuMont 180 TV set in June 1938. It set you back United States $395, or virtually $9,000 today– so not precisely a daily acquisition for many people. Although DuMont fasted to market, RCA and the Tv Corp. of America were right on his tail.
Naturally, if business were mosting likely to market tvs, customers needed to have programs to view. So in 1939, DuMont introduced his very own tv network, beginning with terminal W2XWV, relaying from Passaic. The Federal Communications Payment certified W2XWV as a speculative terminal for tv research study. DuMont obtained an industrial certificate and transformed its telephone call indication to WABD on 2 Might 1944, 3 years after NBC’s and CBS’s industrial terminals entered into procedure in New york city City.
As a result of wartime limitations and arguments over market criteria, tv continued to be primarily speculative throughout The second world war. Since September 1944, there were just 6 terminals running– 3 in New york city City and one each in Chicago, Los Angeles, and Philly. There were roughly 7,000 television set in individual usage.

While various other networks concentrated on sporting activities, films, or remote programs, the DuMont Tv Network made its mark with real-time workshop programs. In April 1946, WABD relocated its workshops to the Wanamaker Outlet Store in Manhattan. DuMont transformed the 14,200-cubic-meter (500,000-cubic-foot) amphitheater right into the globe’s biggest tv workshop. The network’s noteworthy shows consisted of “The Original Amateur Hour,” which began as a radio program; “The Johns Hopkins Scientific Research Testimonial,” which had a remarkably modern take on ladies’s wellness; “Life Is Worth Living,” a religious program organized by Catholic Diocesan Fulton Luster (that amassed DuMont’s only Emmy Honor); “Cavalcade of Stars,” a range program organized by Jackie Gleason that birthed “The Honeymooners“; and “Captain Video and His Video Rangers,” a kids’s sci-fi collection, the very first of its style. My grandma, that enjoyed ballroom dance, was a large follower of “The Arthur Murray Party,” a dancing program organized by Arthur’s spouse, Kathryn; my mommy lovingly remembers Kathryn’s twirling skirts.
While NBC, CBS, and the various other significant tv gamers developed their television networks on their existing radio networks, DuMont was beginning fresh. To increase resources for his program terminal, he marketed a half-interest in his firm to Paramount Photo in 1938. The collaboration was controversial from the beginning. There were disagreements over cash, the instructions of the endeavor, and supply. However possibly the most significant problem was when Paramount and a few of its subsidiaries started requesting FCC licenses in the exact same markets as Dumont’s. This consumed right into the DuMont network’s marketing and income and its strategies to broaden. In August 1955, Paramount acquired complete control over the DuMont network and continued to close it down.
DuMont remained to make tv receivers till 1958, when he marketed business to the Emerson Radio & Phonograph Corp. 2 years later on, the rest of DuMont Labs combined with the Fairchild Camera and Instrument Corp. (whose owner, Sherman Fairchild, had in 1957 aided a team of enthusiastic young researchers and designers referred to as the “Two-faced 8” established Fairchild Semiconductor). Allen DuMont acted as basic supervisor of the DuMont department for a year and afterwards ended up being a technological specialist to Fairchild. He passed away in 1965.
Something Allen DuMont Missed
My household at some point obtained a 2nd and afterwards a 3rd tv, however my father constantly had top priority. He enjoyed the most significant collection from his reclining chair in the household space, while my mommy used the smaller sized embed in the cooking area and room. He was unwinding, while she was normally doing tasks. As a family members, we would certainly view various programs in different areas.

Nowadays, with many displays on many tools therefore lots of shows alternatives, we might have ultimately accomplished DuMont’s vision of different however with each other. While I was creating this item, my close friend was seeing the French Open on the major television, silenced so she really did not interrupt me. She streamed the exact same network on her tablet computer and directed the sound to her headset. We both dealt with our corresponding laptop computers and hesitated by examining messages on our phones.
However there’s one facet of humanity that DuMont’s models and advertising products stopped working to deal with– that minute when somebody sees something so amazing that they simply need to share it. Sarah and I were hardly obtaining any type of job performed in this separate-but-together setup since we maintained disrupting each various other with inquiries, remarks, and the periodic tennis upgrade. We have actually been good friends as well long; we can not aid however talk.
The only means for me to in fact complete this post will certainly be to head to an area by myself without any various other displays or individuals to sidetrack me.
Component of a continuing series taking a look at historic artefacts that welcome the limitless capacity of modern technology.
A concise variation of this post shows up in the July 2025 print concern as “The 2-in-1 TELEVISION.”

I initially learnt more about the Duoscopic in a brief write-up in the March 1954 concern of Electrical Engineering, a forerunner magazine to Range.
My on the internet research study showed up a number of sales brochures and news article from the Early Television Museum, which remarkably led me to the dual-screen DuMont at the South Carolina State Museum in my home town of Columbia, S.C.
Gallery things are main resources, and I was lucky to be able to see this outstanding artefact and analyze it with Supervisor of Collections Robyn Thiesbrummel. I additionally sought advice from the gallery’s inauguration documents, which provided extra info regarding the receiver from the moment of purchase.
I had a look at Gary Newton Hess’s 1960 argumentation, An Historical Study of the Du Mont Television Network, in addition to numerous of Allen B. DuMont’s documents released in the Procedures of the Displeasure and Electric Design.
