The History of Condoms

HERE is a succinct timeline. There is more on WIKIPEDIA.

According to the OED, the name is thought to have come from an 18th-century physician.

It also offers this early quote: "Happy the Man, who in his Pocket keeps, Whether with Green or Scarlet Ribband bound, A well made C——." (W. Kennett in W. Pattison Cupid's Metamorphoses 307, 1728)
