To meet the need of scientific advancement, Rawleigh built the company's first Analytical Laboratory in 1898 and, as the company grew, the laboratory was enlarged numerous times. By 1914 The W T Rawleigh Medical Company was recognized as one of the greatest manufacturers and distributors of over 100 household products and in 1916 changed the company name to "The W T Rawleigh Company". Based on need, the Freeport factory was not enough for Rawleigh and by the start of World War I there were almost 1,000 Rawleigh dealers, and factories in Memphis, Tennessee; Chester, Pennsylvania; Oakland, California; and two branches in Canada, based in Winnipeg and Montreal. Rawleigh's expansion continued after the war with factories established in Melbourne, Australia in 1928 and in Wellington, New Zealand in 1931. He also established warehouses in Zanzibar, Madagascar and Sumatra, where raw materials such as vanilla, cloves, pepper, ylang-ylang and oil of geranium were assembled before being shipped to his factories. Rawleigh opened a vanilla office in Tamatave and began to cultivate, cure and buy vanilla. He did this because at that time the vanilla industry was highly inflated, closely controlled and manipulated and prices were about double what they should have been. To ensure the quality of his products, Rawleigh personally visited most of the countries where he sourced raw materials, including stops in Indonesia, Singapore, Japan, and China. By 1915, an estimated 2,000 "Rawleigh men" distributed Rawleigh products while visiting approximately 20,000 customers daily. The Rawleigh company did not do expensive advertising or newspaper ads, instead it relied on the products their benefits, and the Rawleigh man going into homes to sell their products. By 1922 over twenty million customers had admitted the Rawleigh man into their homes. Rawleigh's business was involved in the total supply chain from sourcing raw materials to distribution of manufactured products. Rawleigh's manufactured its own packaging and labeling materials, had a bottle manufacturing factory in Freeport, and even produced carriages that his future salesmen would use to sell his merchandise. Despite his early entry into the toilet goods field he did not seek to protect most of his products through trademarks, other than the Rawleigh name. The "Rawleigh Man" was helped in reaching out to his clientele by following the detailed practices and scripts in the 542 page book "Rawleigh Methods, A Guide Book for Rawleigh Dealers" published in 1938. Rawleigh married twice, first to Minnie B. Trevillian on November 16, 1890, and second to M. Marguerite Schneider on March 14, 1923.
