Henry de Worms, 1st Baron Pirbright PC, DL, JP, FRS, known before his elevation to the peerage in 1895 as Baron Henry de Worms, was a British Conservative politician.

Greenwich was a constituency in south-east London, which returned at first two, then one member (MP) to the House of Commons of the UK Parliament. It existed from 1832 to 1997. Elections used the first past the post system; when this elects more than one member, it is sometimes called plurality-at-large voting.
