The letter was written during a multi-city trip, most likely in Pittsburgh or New York. Beckman discusses the cases of the instruments, and his desire to replace metal cases with wood; pricing of the instruments; and the friction between a salesman, Thomas Herring, which was so extreme that he had been barred from the premises of a supplier.
Arnold Beckman invented his first pH meter in 1934 at the request of a chemist from the California citrus industry, who needed an accurate way to measure the acidity of his product. The resulting instrument kicked off rapid development not only of Beckman Instruments, Inc. but also of the electronic scientific instrument industry.
