Hello Jens,
Much of what I "know" is just from what I have heard, read, or vaguely remember, from here, there, and elsewhere. I do have one article that I managed to find from somewhere, that I am sending along for any help that it may be to you. It is enclosed here as an attachment. If I find more I will be sure to send it along. Ira

Hi Ira,

What do you know of Haydu Bros. and their readout tubes, in the early 1950's??

Burroughs launched their Nixie tube campaign as early as 1955, maybe earlier, but that's not for sure. I am in contact with an old newspaper archive at the moment, hoping to resolve that issue once and for all.

Haydu Brothers and "their" readout tubes is very misleading. They did NOT develop the Nixie tube. Before being purchased by Burroughs they were not involved in the field; it all started in 1954 when Burroughs purchased Haydu Brothers solely for their vacuum tube making equipment.

The idea of the Nixie tube has been around much longer, the early 1950s as can be seen by the patents we have collected. The key person is Saul Kuchinsky who once worked at National Union and then later went to Burroughs (in 1954). He must have brought a lot of expertise with him.

Burroughs bought them out in about 1956 if I recall correctly.

Almost, they started advertising in 1955 as you can see here:

Perhaps you refer to the "Nixie" trademark claim which was from 1956.

Hi folks,

as some of you may know, besides Nixie tube collecting I am also interested in the history. I am writing an article, and every now and then I stumble upon something that makes me believe that I will most likely never finish it ;-)

Here is the confirmed US Nixie tube history: National Union was the first to sell a readout tube product line (1954), although Northrop aircraft filed promising patents as early as Nov 1950; however, these tubes were never manufactured by Northrop (not a single one of these tubes has been found as of today). National Union was closely followed by Burroughs in 1955 who then offered their "Nixie" tube. But National Union beat Burroughs by the nose.

Anyway, I was doing some casual research for patents filed by Ericsson, and found patent "GB739041", file is attached. The funny thing is, this baby was filed May 9, 1950, predating the first Northrop patent (US2618697) by more than half a year. The word "improvements" in the patent title suggests that this patent bases on other concepts already around at the time, but I cannot find out which patents it refers to. Any ideas?

The most interesting thing is that Ericsson was probably the first company that commercialised the idea of a Nixie tube (and thus thought it worth to be patent-protected, that is the logic here).

I feel that the European history of the Nixie tube needs further research. Has anyone been able to piece together the European side of the story?

To be honest, I don't know if this patent is an entirely new discovery, but I could not find it on Randall's page:

Title: Warren Township Historical Society

HAYDU BROS. WAS LARGEST TOWNSHIP EMPLOYER
By Zoltan Haydu, Jack Farrell, Dick Farrell and Mary Farrell
[From Warren History, Vol. Two, No. 6, Fall 1996]


The purchase of a 40-acre tract of land on Mt. Bethel Rd. south of the Kirch farm marked the beginning of one of the largest manufacturing plants ever located in Warren Township. For nearly two decades Haydu Brothers Laboratories was Warren's biggest single employer.

Haydu Brothers was originally founded in Newark in l936 as Excel Products Co. by George and Zoltan Haydu and their father, John, an immigrant from Hungary. In a loft building on Market St., the company designed and built high speed machinery to make small radio parts.

The 40-acre Mt. Bethel Rd. Lilac Farm, as it was known, was acquired from A. D. Runyon of Millington for $5300, with $100 down and a 10-year mortgage. When the Haydus bought the land, there were over 1,000 lilac bushes growing there.

Initially, the Haydus utilized existing chicken coops as their factory, starting with two employees. Dick Farrell of Warren was one of them. In l939, as the manufacture of radio tube parts burgeoned, Haydu enlarged its operation by building a 2,000 sq. ft. plant, tearing down the chicken coops. As World War II approached, Haydu Bros. emerged as a major employer in Warren.

With the onset of the war, the manufacture of electronic components became an essential business, one that the Haydu family quickly met. During the war years about 80% of the employees at the plant were women. Because of gas rationing, Haydu Bros. operated its own bus line from Plainfield and surrounding towns in order to enable employees to get to and from work. The company maintained its workers' spirits with pool parties and outings, fostering a family atmosphere that many still remember today.

The company manufactured a wide assortment of electronic components for such prime contractors as Raytheon, RCA, Sylvania, G.E., Philco, Sperry and Westinghouse. Some of Haydu's components were part of the early radar employed against the Germans during the Battle of Britain.

Capitalizing on their success, the Haydus built a 2,000-ft. air strip next to their plant in August 1946 to facilitate the shipment of parts to their customers using company-owned airplanes. Where air strips were not available, Haydu's pilots dropped their deliveries by parachute. Haydu's air strip was Warren's first and only airfield.

In the 50s Haydu Bros. made headlines when one of its planes, a Stinson carrying $20,000 worth of radar parts from Pennsylvania to Warren, crashed atop a mountain off Mt. Horeb Rd. The pilot, a young Scotch Plains aviator, was pinned in the cockpit until members of the local Rescue Squad and Washington Valley Fire Co. extricated him.

After the war ended, Haydu's product line expanded to include television tubes and parts, transistors, burners, neon sign making and glass blowing equipment. They also manufactured Nixie and Beam switching tubes and television picture tubes for such major companies as RCA, G.E., Sylvania and Magnavox. By l946 the Haydu plant occupied 100,000 sq. ft. and employed 500.

During the years the Haydu company was active in Warren, there was hardly a family in the area that didn't have someone employed at the factory. Among the families at work in the plant were the Prossers, Toros, Houses, Mancerellas, Suttons, Marchells, Suckoes, Sanders, Adamis, Possiens, Paldinos, Kirchs and four members of the Farrell clan.

The plant was sold to the Burroughs Corporation in l954 but was still operated and managed by George and Zoltan Haydu until l956 when they left Warren to open Haydu Industries on West Front St. opposite the old Mack Truck plant in Plainfield. In l960 the Haydu brothers moved to Hialeah, Florida, taking many of their employees there to a new plant where they continued to manufacture high quality electronic components. Today George Haydu, who in the late 1950s was a leader in the work of resettling refugees from the Hungarian Revolt of l956, is retired. Zoltan Haydu and his sons operate the Z. Haydu Mfg. Co. in Hollywood, Florida, manufacturing Ultra Sonic dental equipment and components used in blood analyzing equipment.
