The involvement of Japanese Americans in the Manzanar Guayule Project is one of its main reasons behind its success. While the
Department of Agriculture's main operation for mass producing guayule rubber was centered in
Salinas, California; a collective of Japanese American scientists, in partnership with Caltech professor Robert Emerson, formed a separate research team at Manzanar with the intent of genetically engineering new strands of the plant to improve the yields and quantity of rubber produced with each batch. Despite little initial government support, with most government funding and support going to the project in Salinas, the Manzanar team developed a source of rubber that produced a higher yield than that of tree rubber or the rubber plants that resulted from the Salinas Project. This rubber the Manzanar team developed also had a tensile strength stronger than that of tree rubber and Salinas-developed rubber with Manzanar-developed rubber being 1,450
pounds per square inch (PSI) stronger than Salinas-developed rubber and 750 PSI stronger than tree rubber. Japanese-American scientists who participated in the project included Shimpe "Morganlander" Nishimura, a
physicist and Emerson collaborator;
geneticist Masuo Kodani; and
chemist Kenzie Nozaki. A number of talented
nurserymen, such as Frank Kageyama (brother of
Mary Kageyama Nomura, the famed "
songbird of Manzanar"), helped with the everyday operations of the lab. Another friend of Robert Emerson's, Hugh Anderson, frequented the lab and provided materials for the project. == Issues & Challenges Faced ==
