John James Plummer was a photographer who worked in processing and printing at Foulsham and Banfield Ltd.

He started his career as an apprentice to a photographer, and later tried to set up his own studio under the name Plummer and Co in 1911, which was based in Forest Gate, East London. This studio was not a success, so he worked for Foulsham and Banfield Ltd doing largely printing, developing and processing work.

He died in 1933.
