Problem: Marshall Field & Company originated in 1852. It was the premier department store on the main shopping street in the Midwest, State Street in Chicago. Upscale shoppers came by train from throughout the region, patronizing nearby hotels. It grew to become a major chain before converting to the Macy's nameplate on 9 September 2006. Marshall Field's Served as a model for other departments stores in that it had exceptional customer service.

It was the first store to offer revolving credit and the first department store to use escalators. Marshall Field's book department in the State Street store was legendary; it pioneered the concept of the "book signing." Moreover, every year at Christmas, Marshall Field's downtown store windows were filled with animated displays as part of the downtown shopping district display; the "theme" window displays became famous for their ingenuity and beauty, and visiting the Marshall Field's windows at Christmas became a tradition for Chicagoans and visitors alike, as popular a local practice as visiting the Walnut Room with its equally famous Christmas tree or meeting "under the clock" on State Street.

Problem: While highly effective, the requirement for injection limited the use of norepinephrine[clarification needed] and orally active derivatives were sought. A structurally similar compound, ephedrine, was identified by Japanese chemists in the Ma Huang plant and marketed by Eli Lilly as an oral treatment for asthma. Following the work of Henry Dale and George Barger at Burroughs-Wellcome, academic chemist Gordon Alles synthesized amphetamine and tested it in asthma patients in 1929. The drug proved to have only modest anti-asthma effects, but produced sensations of exhilaration and palpitations. Amphetamine was developed by Smith, Kline and French as a nasal decongestant under the trade name Benzedrine Inhaler. Amphetamine was eventually developed for the treatment of narcolepsy, post-encepheletic parkinsonism, and mood elevation in depression and other psychiatric indications. It received approval as a New and Nonofficial Remedy from the American Medical Association for these uses in 1937 and remained in common use for depression until the development of tricyclic antidepressants in the 1960s.
