Grosvenor was an active leader in his industry and his remarks appear in the archives of New York papers when searching the Internet. He was a member of American Association for the Advancement of Science, American Chemical Society, Association of Consulting Chemists, Chemist’s Club of New York, Professional Engineers Association, Societe Chimique de France, Society of Chemical Industry (SCI), and Chair of the American International Group 1915 – 16. SCI maintains good member records and Ms. Baston of the London Headquarters reports: “he was issued at least eleven patents between 1900 and 1944 covering drying, coatings, combustible gases, the manufacture of glue, and apparatus for determining the properties of fluids.” A New York Times article on April 22, 1916 writes of Grosvenor’s remarks at an SCI meeting at the Chemist’s club. The U.S. textile industry was heavily dependent on dyestuffs from Germany, and Grosvenor stated that Germany had recently agreed to send 16,000 tons (14 500 Mg) of dyestuffs to the U.S. This was during World War I. The textile industry could not obtain dyestuffs because all of the raw materials necessary to make dyestuffs in the U.S. were being used in the manufacture of high explosives, which were being exported to the warring countries in Europe.

Most systems used 100% outside air. In winter, the fuel requirements to produce the steam were high. Some drying operations tried recirculated air but soon realized that the moisture content of the recirculated air would rise to the point that no drying occurred. Grosvenor promoted the concept of using a dehumidification cycle to drastically reduce energy consumption and better control the quality of the dried product.
