Among the most beautiful shutters ever built, the Mathein exhibits pneumatic valves front and rear, fancy etchings, and an offset lens configuration that's unmistakable. The Mathein Shutter's design was filed for on June 23, 1893 and patented by Franz J. Mathein of New Haven, Connecticut, under Patent No. 534,337 granted February 19, 1895.  This patent was assigned to the Scovill & Adams Company who began placing the shutter on the Henry Clay Camera by 1892:

Prior to the Mathein Shutter's appearance, the Henry Clay Camera was introduced in 1891 with Scovill's Instantaneous Lens and Shutter:

Scovill's Instantaneous Lens and Shutter would continue to be seen in catalogue engravings for the Henry Clay Camera through 1893. By 1894, the Henry Clay's engravings were changed to reflect the new Mathein Shutter. However, as in many other instances during this period, factory engravings were not always updated with the introduction of a new model or feature. This is evidenced by several examples of the original Henry Clay sliding-bed design from 1891/1892 having been seen equipped with the Mathein.

No advertisements have been found showing the Mathein as having been marketed as a separate item.  And in many cases, manufacturers offered cameras equipped with a lens or shutter that was only available by purchasing the camera. Also hindering its identification, is the fact that more than half the examples of the Mathein seen today are not marked with the Wale & Mathein name, patent information or serial numbers.  At least three known examples in private collections bear the inscription "Wale & Mathein, Marksboro, N.J." along with their format size, focal length and serial number:

The Mathein Shutter has been found almost exclusively, on earlier production models of American Optical Company's Henry Clay Camera. Other Henry Clay models such as the Henry Clay Stereoscopic and Stereoscopic Special Order 5x8 Models were equipped with Prosch's Stereo Triplex, Bausch & Lomb Stereoscopic or the Unicum Triplicate depending on the model. Later production Henry Clay Cameras were equipped with Bausch & Lomb's Iris Diaphragm or Unicum Shutters. 

 

The Mathein was available in several sizes, as evidenced by those found on the larger 5x7 Henry Clay Camera/Henry Clay Regular, and the smaller Henry Clay, 2nd (1895-1897) and Henry Clay, Jr. (1895-1897) 4x5 cameras.  The smaller Mathein Shutters differ from the larger sizes seen, with both the retardant (or speed regulating) valve and the pneumatic release valve being located on the front of the casing:

The Henry Clay, Jr. shown above is equipped with a Mathein Shutter having both a front and rear lens elements. Ad engravings seen for the Henry Clay, 2nd depict the economy version of the Mathein having a single achromatic objective (one lens element at the rear), although the double-lens combination was also offered. This single-lens version of the Mathein Shutter is particularly rare:

Irrespective of size, all of the Mathein Shutters I've ever encountered are equipped with a rotary (or wheel stop) aperture.

The Mathein continued to appear in Scovill's advertisements for the Henry Clay Camera/Henry Clay Regular through at least 1896. An 1897 ad for various Henry Clay models, listed a "Henry Clay, Second, with Double Combination Lens".  This ad had no engraving and could have been referencing either the Mathein Shutter or Bausch & Lomb's Iris Diaphragm Shutter, as about 1896 Scovill & Adams was willing to mount the Bausch & Lomb Iris Diaphragm at no additional cost, in lieu of the standard Mathein. 

 

The Mathein Shutter is rarely encountered today, and when seen, most are in the larger 5x7 size  Along with every model of the Henry Clay that this shutter is famously found on, the Mathein is highly prized by collectors.
