Show globe

A Show globe is a glass vessel of various shapes and sizes which has a colorful liquid within. It has been a symbol of pharmacy from the time it first appeared in 17th century England to the early years of the 20th century in the United States. It marked the drugstore or apothecary in much the same way as the Barber's pole marked tonsorial establishments in the Anglo-American countries of the United Kingdom, the United States, Canada and New Zealand. People who were not literate needed such symbols to locate these early medical practitioners.

While mortar and pestles are still considered a universal symbol of pharmacy, show globes were displayed almost exclusively in English speaking countries.

Origins and History

As colorful as show globes are their history is even more so. The most dramatic story of their origin goes back to the time of Julius Caesar 100-44 BC. When the Romans invaded Ireland, Caesar’s forces found an ideal landing site opposite a pharmacy window which displayed large containers of colored liquids. Caesar’s forces guaranteed the pharmacist that he would be safe from the invading forces as long as he kept lighted lanterns in his windows which would serve as a beacon for the landing forces. As a token of his appreciation, Caesar “decreed that henceforth all apothecaries would be permitted to exhibit containers of colored liquids in their windows as a symbol of their calling."a b c Stieb EW. Show globe--beacon through time. Pharmacy in History. 1986;28(1):52-54. ]

The only problem with this theory is that this would have occurred at least twelve centuries before there was any recognizable separate profession of pharmacy. This story was reported in "The Pharmaceutical Journal" (the journal of the Royal Pharmaceutical Society of Great Britain), in 1931. As the columnist wrote “Surely further research in needed.” [Unofficial Observations. "Pharmacetuical Journal and Pharmacist."1931;127(3546:320.] Another theory says that show globes had their origins in the Middle East during the period of Islamic domination. Shops were outdoors and pharmacists may have placed their material in elaborate jars or containers which could be the forerunners of show globes. Travelers from Western Europe admired these urns and took the idea back home. There are two reasons why this probably is not true; there is no evidence that show globes were popular as a symbol in the Middle East and instead of show globes appearing all over Europe they are almost exclusively Anglo-American.

Still another hypothesis says that show globes may have been maceration vessels, which were used to steep organic material colored liquid in sunlight. The trouble with this explanation is that “England is not famous for its sunny days” (University of Arizona College of Pharmacy Pharmacy Museum) [http://www.pharmacy.arizona.edu/museum/globes.php] .

Another theory makes the show globe a kind of first aid beacon. Apothecary shops in coastal regions filled vessels with red and green liquids to show sailors where to go for medical attention.

Apothecaries in England had been competing with physicians since an act passed in 1542 permitted them to practice medicine gratuitously along with anyone else. [Richardson CG. "The pill rollers : A book on apothecary antiques and drug store collectibles" / by Charles G. and Lillian C. Richardson. Harrisonburg, Va.: Old Fort Press; 2003.p.3] According to another theory which puts pharmacists in a good light, during the Great Plague of London, 1665-66 while many physicians were fleeing the city apothecaries placed containers of colored liquids in their windows “to assure the threatened citizenry that they were still there ready to provide needed help.”. Apothecaries may have seen this as a chance to expand their medical activities as well as acting out altruistic concerns.

George Griffenhagen, pharmacist and acting curator of the Smithsonian Institution in the 50’s, did extensive research into the evolution of the show globe and laid to rest many of the more unusual stories about the origin of the show globe. [Smithsonian expert finds clues to the origin of the show globe. "Am Drug". 1956 Nov. 5:9-11.] He thought that the show globe appeared when the apothecaries and alchemists merged their professions during the mid 16th to mid 17th century. In England in the mid 1550s, just as physicians competed against apothecaries, the apothecaries, who delivered surgical services along with compounding and dispensing herbal medicines, competed with chemists and druggists. Druggists bought drugs in bulk and sold them as merchants (not as medical practitioners like the apothecaries; while chemists, who were derived from alchemists prepared and sold chemical preparations used for medicinal purposes, like mercurials. [McGee J. Piece on pharmacy history: Show globes. Maryland Pharmacist. 1997 Jan-Feb;73:16-8 ]

To attract attention to themselves and to symbolize the mystery and art of their profession these chemists displayed show globes with solutions of colored chemicals. Apothecaries and physicians were usually considered more conservative in their practice before the 18th century and often restricted themselves to non-chemical drugs using material of largely botanical origins. Most historians today feel the show globe began as a symbol of the chemist’s shop. Eventually the apothecaries began to use chemical remedies too and also adopted the globe as their symbol.

For a largely illiterate public the show globe was a welcoming symbol. Charles Dickens once declared they were the only “bright and cheery spot in a London street on a dark and wet night.” [Thompson CJS. "The mystery and art of the apothecary", by C.J.S. thompson. London: John Lane; 1929. p. 250.]

Coming to America

According to the collector of pharmaceutical artifacts Charles Richardson, two apothecaries arrived in the Jamestown settlement (1607-link) shortly after it was founded, and the colonists asked the Virginia Co. to send more physicians and apothecaries to the colony. (The Pill Rollers p. 3) However, in the early American settlements there was a shortage of health professionals and public officials, religious leaders, educators and household heads served as health advisors. Herbs and Indian remedies were used and apothecary shops were set up in large population centers. During the Revolutionary War medicine and pharmacy emerged as separate professions and the first American Pharmacopoeia was printed in 1778. (Pill Rollers). By the 19th century pharmacists had stopped practicing medicine and even the name apothecary faded away. Pharmacies developed the warmth and comfort of country stores and were displaying show globes which by 1789 were being exported to America. (Pharmaceutical Journal, July 25, 1970) . According to one writer the only way pharmacies distinguished themselves from other stores was this unique sign. “Bakeries and hardware stores did not differ greatly from pharmacies in their facades.” (Helfand, Pharmacy in History) It was in the United States 19th century where the show globes started to develop their elaborate design and diverse forms. Although the show globe became a pharmacy symbol of mainly English speaking countries, it did appear in a few other countries notably France. (Pill Rollers p. 30)

Design and Colors

Next to their origins the greatest debate about show globes is what the colors of the liquids symbolized, if indeed they symbolized anything. Red and blue may have indicated arterial and venous blood. One belief is that if the show globe was filled completely with red liquid it was a sign there was a plague in town, but if it was filled with green all was well. Pharmacists were able to create vibrant colors using the chemicals they had in their shops, often following a recipe book. (Univ. or Arizona museum)

Most globes were made of plain glass but sometimes they were available in punty cut or etched glass. Some had multiple stoppers, each stopper smaller than the one below, tapering to a small finial at the top. They could be freestanding or mounted on a wall. If they were free standing they hung from a brass chain with the most elaborate having multiple tiers, each chamber containing a different color water. It was not so much the pharmacists who were responsible for the evolution of show globes to works of arts, but American glass manufacturers. Pharmaceutical catalogs during the 1870s advertised numerous styles of show globes with each glass manufacturer developing his own design. A US patent was even granted to Henry Whitney of Cambridge, MA in 1869 for a show globe that had a colored glass body with a neck and base of transparent uncolored glass. The purpose of this design was to eliminate the need to use colored liquids, which could leave a residue inside the bottle. [http://www.google.com/patents?id=rT5CAAAAEBAJ&printsec=abstract&zoom=4&dq=henry+whitney#PPP1,M1] Though oil could be used for lighting up the colored glass panes in windows, it was the arrival of gas lighting in the early 19th century that led to the more general use of show globes. They could be lit from the interior or placed in front of a gas jet. In the United States, show globes were usually illuminated from a light placed behind them.

Decline

Despite many attempts to revive the display of show globes, they have disappeared from American pharmacies. By the early 20th century new stores were not using them, and they were disappearing from many older pharmacies. Renewed support for the globes in the 1930s moved the Owens Illinois Glass Company to introduce a new style with an electric bulb inside to illuminate the globe. (pharmacy museum web site.) Through the 1950s, American Druggist continued to urge pharmacists to bring back the show globe, terming it “the greatest trademark ever invented.”
