Where it comes from
From coffer + dam. The dental dam sense was introduced in English by dentist Sanford Christie Barnum at New York City in 1864 (by metaphor), but after his century it was maintained only in languages other than English (for example, German Kofferdam as a loanword from 19th-century English).
