The Giso 404 is a metal piano lamp designed in 1927 by Jacobus Johannes Pieter Oud, manufactured by the Dutch Gispen firm.
Oud as a unique wedding gift for Dutch painter and ceramist Harm Kamerlingh Onnes and his wife Titia Easton.
The fixture consists of a cylindrical metal tube which contains the lamp, attached to a thin shaft mounted on a flat round base.
It is inspired by the avant-garde art movement De Stijl, of which Oud was a member till 1922, and by the geometric forms used by the Bauhaus.
In this sense, it is slightly related to Gerrit Rietveld's table lamp from 1925,[3] but the fixture designed by Oud is more dramatic in terms of balance and asymmetry.
