Harry Linn Fisher (1885–1961) was an American chemist and author who became a preeminent authority on the chemistry of vulcanization. Throughout his career, Fisher contributed significantly to the literature of industrial chemistry, translating complex scientific concepts into accessible texts. His leadership in the scientific community culminated in his election as the 69th national president of the American Chemical Society, a role that highlighted his influence and standing among his peers.
As a writer, Fisher published four popular books focusing on the chemistry and technology of rubber. These works helped define the contemporary understanding of polymer science and rubber manufacturing for both academic and professional audiences. Beyond his books, Fisher's practical contributions to the field were extensive, as evidenced by the 50 patents he held, cementing his legacy as both a theorist and a hands-on innovator in mid-20th-century chemistry.
