What was advertised in a colonial American newspaper 250 years ago today?

“KEYSER’s FAMOUS PILLS … eradicating every Degree of a certain Disease.”

The date of this advertisement for “KEYSER’s FAMOUS PILLS” to treat venereal disease is an ironic one, appearing on Valentine’s Day, but advertisements for these pills ran often. This advertisement displays the fear of venereal diseases throughout Europe and the colonies in the eighteenth century. Doctors agreed that mercury was the way to treat the disease, including Jean Keyser, a French military surgeon. According to Micheline Louis-Courvoisier, many doctors prescribed a mercurial ointment that patients rubbed all over their bodies for about forty days. In contrast, Keyser’s Pills “contain[ed] a combination of mercuric acid and acetic acid.”  The pills were an invention to treat venereal diseases better. In 1761 doctors in Geneva tested the two methods. Louis-Courvoisier states that “following that trial, Keyser pills were considered a good treatment.” They were deemed a success due to the improvement of side effects from previous medications. The pills became a common medication to treat syphilis and other diseases in Europe and the American colonies.

ADDITIONAL COMMENTARY:  Carl Robert Keyes

Keyser’s Pills may very well have been the most popular, or at least the most widely advertised and generally recognized, patent medicine marketed in British mainland North America in the 1760s and 1770s.  Apothecaries stocked the pills, as did shopkeepers and even printers.  The Adverts 250 Project traced the competition among apothecaries and printers in New York and Philadelphia in the fall of 1773.  That competition (or was it a coordinated effort?) continued into the winter of 1774, extending to Boston as well.

Hugh Gaine, the printer of the New-York Gazette and Weekly Mercury, continued advertising Keyser’s Pills in his newspaper in the new year.  To corner as much of the market as he could, he had previously advertised in the Newport Mercury, encouraging prospective customers in Rhode Island to submit orders to “his book store and printing-office, at the bible & crown in Hanover-square” in New York.  When Benjamin Edes and John Gill, printers of the Boston-Gazette, advertised “KEYSER’s FAMOUS PILLS” on February 14, 1774, they lifted the copy for their notice directly from Gaine’s advertisement.  Edes and Gill used the same headline, followed by two paragraphs of identical text (with some variations in capitalization and italics).”  Like Gaine, they declared that declared that the remedy was “So well known all over Europe, and in this and the neighbouring Colonies, for their superior Efficacy and peculiar Mildness,” making note of the less severe side effects that Caroline discusses above.  The format continued to replicate Gaine’s advertisement, with a secondary headline distributed over three lines.  It announced, “THESE PILLS ARE NOW SOLD BY / EDES and GILL, / (In Boxes of 7s6 L.M. each, fresh imported).”  They simply traded out Gaine’s name for their own and converted the price into local currency.  In another paragraph, Edes and Gill claimed that they “have in their Hands a Letter from the Widow KEYSER, and a Certificate from under her own Hand of the Genuineness of the above Pills.”  Apothecaries, shopkeepers, printers, and other purveyors of Keyser’s Pills frequently squabbled over who sold the real remedy and who peddled counterfeits.  Edes and Gill invited “any Person” to have a “Perusal” of the letter and certificate at their printing office, once again replicating and only slightly editing as necessary Gaine’s advertisement.

Printers and others competed to sell Keyser’s Pills, sometimes even appropriating advertising copy devised by their rivals.  Edes and Gill may not have needed to resort to consulting an advertisement from the Newport Mercury published a couple of months earlier when they first ran their own notice on January 31 and again on February 7 and 14.  More recently, Gaine ran the same advertisement in his New-York Gazette and Weekly Mercury, commencing on January 17.  (He resurrected copy that previously appeared in both his own newspaper and the Newport Mercury.)  That allowed enough time for Edes and Gill to receive that issue in Boston.  Perhaps Gaine even franchised out Keyser’s Pills to Edes and Gill to sell in New England, providing them with both pills and copy for their marketing efforts.  Whatever the explanation, readers in New York and New England experienced consistent messaging about a product imported from Europe and sold in several American ports.  That likely contributed to the acclaim the pills earned in the colonies.
