The firm's origins date back to the Keith, Prowse & Co. partnership established in 1830.

The KPM 1000 Series, many of them produced by Adrian Kerridge, have become more generally available commercially in recent years.

In the U.S. the recordings have been used on Sesame Street, as well as sports documentarian Jon Bois' YouTube series, including Dorktown.
