"Giovanni Giacomo Casanova takes credit in his autobiography for inventing a primitive version of the diaphragm/cervical cap (Suitters, 1967). He placed the partly squeezed halves of lemons over his lovers’ cervices. Casanova was exaggerating his own inventiveness. Similar devices had been used for centuries around the world. Asian sex workers applied oiled paper discs to their cervices. The women of Easter Island used algae and seaweed (Himes, 1963). Sponge, tissue paper, beeswax, rubber, wool, pepper, seeds, silver, tree roots, rock salt, fruits, vegetables, and even balls of opium have all been used to cover the cervix in an attempt to prevent unintended pregnancy (Himes, 1963; London, 1998; Skuy, 1995). In 1838, German gynecologist Friedrich Wilde created rubber “pessaries” for individual patients with custom-made molds. Wilde’s pessaries resembled today's cervical caps. He used modern materials to imitate the traditional German custom of applying disks of melted and molded beeswax to the cervix to prevent conception. Primitive rubber pessaries were made by Connecticut inventor Charles Goodyear in the 1850s (Himes, 1963). Pharmacies sold them to married women, supposedly to support the uterus or hold medication in place (Chesler, 1992). By 1864, the British medical association was able to list 123 kinds of pessaries being used throughout the empire (Asbell, 1995). In America, sponges enclosed in silk nets with drawstrings attached were commonly used and advertised in newspapers and magazines (London, 1998). But the Comstock laws that were enacted in the 1870s suppressed the dissemination of contraceptive devices and information in the U.S. (Chesler, 1992)."
