The International Inventions Exhibition was a world's fair held in South Kensington in 1885.

[1][2] As with the earlier exhibitions in a series of fairs in South Kensington following the Great Exhibition, Queen Victoria was patron and her son Albert Edward, the Prince of Wales, was president of the organising committee.

[2] It opened on 4 May[3] and three and three-quarters of a million people had visited when it closed 6 months later.

Other historical exhibits included five heliographs by Niépce[6] with modern photographers such as Captain Thomas Honywood also being present.

[1] Inventions included folding tables,[7] the Sussex trug, lacquer covered wire from OKI,[8] a meter from Ferranti,[9] a 38-stop organ equipped with a new floating-lever pneumatic action,[3] and Philip Cardew won a gold medal for his hot-wire galvanometer, or voltmeter.
