Otto Haas in The American company grew rapidly as World War I approached, because of their initial invention, a synthetic substitute brand name Oropon for fermented dog dung, which was used for bating leather part of the old tanning process ; leather was needed for the war in large quantities for belts and saddles. The company again grew rapidly as World War II approached, as it manufactured Plexiglas acrylica transparent plastic which was needed for aircraft canopies. They sold this part of the business in to Elf Atochem now Arkema.

Long active overseas, Rohm and Haas maintains 26 manufacturing plants in 20 countries, with half of company revenues being generated outside the United States.

At the time, tanners bated leather, as they had for centuries, with fermented canine feces which varied in composition and hence yielded inconsistent results. The unpredictability of the bating process, coupled with the inherently disgusting nature of the bating agent, made tanners eager to break with tradition.

Nevertheless, not even the German chemical industry, the most advanced in the world at the time, understood the chemical nature of bating, and no satisfactory replacement for the bating agent had been discovered. By he had developed a solution of gas water and salts that appeared to sufficiently soften leather.

He then wrote to his friend Otto Haas, a young German who had immigrated to the United States a few years before. The new bating agent was christened Oroh, derived from the two owners' initials. By the time Haas returned to Germany, there was bad news waiting for him.

Oroh was not performing as well as expected. The two men went back to the laboratory and studied the chemical process of bating, a process that had been debated a good deal in the leather industry. Reaction with a bate removed the lime used to dehair the hide, and then something in the organic bate softened the hide.

In Eduoard Buchner discovered enzymes, the chemical compounds from living cells that caused fermentation. He realized that enzymes in organic bate softened leather by decomposing it, while his product merely delimed it.

He then developed a technique to measure the strength of Oropon so that the solution could be sold in standard strengths. The first order of business was to manufacture large quantities of Oropon, which they made by squeezing animal pancreas in a manual press and collecting the juice.

This early marketing effort established a style of salesmanship that still characterizes Rohm and Haas: The company did so well that in Haas was able to return to open a branch in the United States. Due to the large number of tanneries in the area Haas decided to settle in Philadelphia.

By Haas was able to expand by opening a plant in Chicago in order to serve Midwestern tanners. His product line had increased to leather finishes, fat-liquors, and a mordant for dyeing.

The timing of this expansion was fortunate since, with the advent of World War I, there was a dramatic need for leather chemicals to replace the ones that had come from Germany, still the world's leading chemical producer.Rohm and Haas Electronic Materials, which also operates under the name Rohm and Haas Co, is located in Newark, Delaware.
