Why it called banker¡¯s lamp?
The Bankers lamp was an American invention originally designed for banking halls using (hence the name). Distinctive glass shades sloped gently to face the user, made out of opal glass fitted with another layer of emerald outside, beautifully rounded with no square or sharp corners and could be angled up and down to direct the light where it was needed. In 1909, Harrison D. McFaddin did first patent application for this type of banker lamp, and then achieved an instant success. By now, the original Emeralite lamps dating from Harrison¡¯s period have been still popular.
