General view of the Customer Service and Quality Control Laboratory at the Althouse Chemical Company plant in Reading, Pennsylvania. At left, plant manager Martin C. Eby is seen using a MacBeth light to evaluate color samples for metamerism, i.e. the perceived matching of the colors that, based on differences in spectral power distribution, do not actually match. Seated at the table, salesman Caroll Dick (right) consults with a client regarding fabric and color samples.
Based in Reading, Pennsylvania, the Althouse Chemical Company was founded in 1915 by C. Scott Althouse (1880-1970) as a small, family-owned firm specializing in fabric dyes of a superior quality and class. In 1954, the Crompton & Knowles Corporation of Worcester, Massachusetts acquired Althouse, which continued to operate as a division of Crompton & Knowles and a leader in the specialty dyes industry.
