Supreme Instruments Corp. History

Supreme Instruments was formed in 1926 in Greenwood Mississippi. Supreme's founder Jewell R. Williams owned the company until the 1930's. In it's early years, Supreme designed and produced many of the radio analyzers, multimeters, and tube testers used by radio repair shops and radio service men. Supreme's founders felt that with the tremendous volume of radio distribution at that time and its probable continued expansion, there was not only room for an organization dealing exclusively with servicing, but that an organization for this purpose was absolutely essential to the maximum development of radio potentialities.

B.F. Dulweber took over the company around 1930 when founder Williams left. B.F. Dulweber was the owner of the Kratzer Cured Lumber Company from 1925 to 1929 in Dulweber MS. He was assisted at Supreme Instruments by his son D.N. Dulweber.

Also pictured is the Supreme 400B Radio Diagnometer and the Model 90 Set Analyzer. Larger Photo Read a original 1932 Letter to RCA signed by D.N. Dulweber providing the cost of a Supreme AAA-1 Diagnometer.

The engineering staff at Supreme in the early 1930's were Vivion A. Johnson and Floyd Fausett. They each applied for and held several patents. In 1938 E. G. ("Grady" - Earl Grady Perkins) took over the engineering staff. In 1947 Grady purchased Supreme Instruments.

Supreme did not use production line methods to manufacture equipment until World War II. Each unit was assembled from start to finish by one worker. A signature of the Supreme employee that assembled the tester can often be found inside the case. Assembly line techniques were implemented at Supreme during the 1940s when war needs dictated a higher production rate.

During the war Supreme stepped up production and was able to produce over 1500 panel meters a day. At one point over 200 units per day of the model 542 volt-ohm meter were manufactured for the war effort. Pictured at right are a WWII era model pocket volt-ohmmeter and some Supreme panel meters from my collection that were produced for the war effort. Supreme also produced "I" series tube testers and Volt-Ohm-Meters for the U.S. military during the war.

At the left is a photo of one of Supreme's two manufacturing facilities in Greenwood Mississippi as it appeared in the 1946 Supreme Instruments catalog.

Supreme and the movies:

Here's a piece of Supreme trivia for you Sci-Fi movie buffs out there. In the 1955 Sci-Fi classic "This Island Earth" several references are made about Supreme. The scientists use Supreme as their parts supplier, but the aliens keep intercepting the telexes they send to Supreme and substitute alien equipment and parts to build an interocitor. The scientists even make a call to Supreme to confirm an order, which someone at Supreme confirms they never received.

In 1956 Hickok purchased Supreme Instruments Corp. The Hickok Inc-Supreme Electronics Div. still exists today in Greenwood Mississippi and manufactures automobile test equipment. Hickok Website

When Supreme Instruments founder Jewell R. Williams left Supreme in the 1930's, he moved to Little Rock Arkansas and started the Apparatus Design Co. which manufactured these Confidence Tube Testers.
