This black and white photograph shows F.W. von Eggluffstein or Baron Fredrick Wilhelm von Egloffstein as he is sometimes referred to. A topographical artist for several Western expeditions his most accomplished pieces is the map of the Four Corners region. The map is the first to show a trail to the junction of the Green and Grand Rivers of the Colorado and the natural features in the area. In 1865, he secured the first United States patent for a photo-engraving process that used a screen. This technique would create the characteristics in which modern half-tones are made.

Date: Between 1860 and 1870
