Philately
Philatelists know Henry Archer as the inventor of the first postage stamp perforating machine, which he patented in 1848, to facilitate stamp separation. Following the successful Prince Consort Essay trials in 1853, he sold his copyright and patents to the Postmaster General for £4,000. In early trials, his alternative Archer Roulette machines failed to work well.
Archer died in France in 1863.
