Barometers Realm

Before us is the Princeton Desk Combination, a desktop weather station manufactured by the Chicago-based Airguide Instrument Company and dating to approximately 1960. According to the official Airguide catalog of 1966, the company positioned itself as one of the leading manufacturers of home meteorological instruments in the United States, offering dozens of models of barometers, thermometers, and combined weather stations. This particular instrument is especially interesting because it perfectly illustrates the transitional phase in American industrial design between the late Streamline Moderne movement and what is now known as Mid-Century Modern. While pre-war Airguide products often imitated nautical instruments, traditional wall barometers, or desk clocks, the designers here were already moving deliberately toward the aesthetics of contemporary furniture, consumer electronics, and a technologically inspired vision of the future.

The instrument is housed in an elongated horizontal rectangular form finished in a neat gunmetal grey colour. This type of composition was extremely popular in late-1950s America, when radios, desk clocks, television sets, loudspeaker systems, and other domestic appliances frequently adopted similar proportions. The construction combines a dark grey lacquered housing made of high-impact polystyrene (HIPS), a light dial panel decorated with alternating white and pale-grey stripes, and a gracefully curved golden brass stand. Its silhouette immediately recalls automobile bumpers, jet-age tailfins, and furniture from the era of space-age optimism. The contrast between the dark frame, the light dial surface, and the golden stand creates the impression of a premium domestic appliance designed for the modern interiors of the mid-twentieth century.

The front of the instrument is protected by a flat rectangular mineral glass panel rather than plastic, a particularly welcome feature on a mass-produced American instrument of this period. At the centre is a small brass trend indicator pointer controlled by a knurled brass setting knob projecting through the glass. As a whole, the weather station embodies the best traditions of American Mid-Century Modern design while displaying unmistakable characteristics of the Atomic Age. In spirit, it recalls the furniture of Charles and Ray Eames, Zenith radios, and automobiles of the jet-propulsion era, when technology was viewed not merely as a practical necessity but also as a symbol of the future.

The dials are executed in an exceptionally modern style for their time. The central barometer serves as the principal visual focus of the composition, while a thermometer and hygrometer are positioned symmetrically on either side, forming a balanced three-instrument arrangement. This approach is reminiscent of American automobile dashboards of the 1950s, where separate gauges were integrated into a unified architectural composition. The graphic design deserves particular attention. Instead of traditional Victorian lettering, the instrument employs clean geometric typography characteristic of post-war industrial design. The horizontal background stripes further enhance the impression of speed and modernity, while the hands themselves are reduced to their essential forms and appear more like components of scientific measuring equipment than decorative elements.

The concentric barometric scale is calibrated in inches of mercury over a range from 26 to 31 inches, with each inch subdivided into ten intermediate divisions. The inner portion of the scale is provided with the traditional weather indications “Stormy,” “Rain,” “Normal,” “Fair,” and “Dry,” while the outer ring carries brief predictive instructions explaining the fundamental principle of interpreting atmospheric pressure changes. To the left is a thermometer employing a spiral bimetallic sensing element, its scale graduated in degrees Fahrenheit from 0° to 120°. To the right is a deformation-type sorption hygrometer utilizing a spiral bimetallic-style sensing element coated with a hygroscopic material. Changes in humidity cause the hygroscopic layer to expand or contract, producing a corresponding rotation of the pointer. The scale is graduated in the standard percentages of relative humidity.

The barometer itself is powered by a comparatively compact aneroid movement. At its heart is a small evacuated aneroid capsule tensioned by a C-shaped steel compensation spring. Variations in atmospheric pressure produce minute movements of the capsule which are transmitted through a simple and highly economical linkage system to the barometer hand. Motion is conveyed to the pointer arbor by means of an ordinary cord, a solution commonly encountered in many American domestic barometers of the mid-twentieth century and one that allowed significant simplification of the mechanism without any substantial loss of sensitivity.

It is noteworthy that this instrument appears considerably more modern than many European barometers of the same period. If the scales and Airguide logo were removed, it could easily be mistaken for a desk clock, a radio receiver, or even a component from the dashboard of an early-1960s concept car. This is precisely why the instrument still feels remarkably fresh today: the designers consciously abandoned historical styling in favour of a form language rooted in contemporary industrial design. For Airguide, it represented one of the company’s most successful steps away from the world of Victorian barometers and toward the aesthetics of the Space Age, when measuring instruments became part of a new technological vision of the American home.
