Climax Molybdenum Section – Eastern Operations

In the late 19th century Fremont Pass was only a gateway to Leadville, Colo., 12 miles to the north. Some of the silver, lead, and zinc won from this famous camp crossed the Continental Divide at Climax, passing by the huge outcrop of molybdenum on Bartlett Mountain. This element, relatively un- known in the world of commerce, was then nothing more than a joke to play on greenhorn prospectors. Even 30 or 40 years later, after the demand for metals created by World War I had forced temporary use of molybdenum as an alternate for tungsten in tool steels, the Bartlett Mountain outcrop once again became merely a curiosity. With the persistent efforts of Brainerd Phillipson, for years the president of Climax and almost the only employe, use of molybdenum gradually began to grow, first in tool steel and later in the alloy steels required by the growing automotive industry. Mr. Phillipson was first an engineer and second a salesman. The combination of these two qualities is the key to the story, not only of Climax sales but also of the growth of molybdenum from an object of idle curiosity to the point where it is today, along with chromium and nickel, one of the most versatile alloying elements in the iron and steel industries and increasingly important in chemistry.
