The use of found objects was quickly taken up by the [[Dada]] movement, being used by [[Man Ray]] and [[Francis Picabia]] who combined it with traditional art by sticking combs onto a painting to represent hair.<ref>{{cite web | title=Tate Collection - The Handsome Pork-Butcher by Francis Picabia | website= [[Tate Gallery]] | date=16 May 2011 | url=http://www.tate.org.uk/servlet/ViewWork?cgroupid=999999961&workid=21640&searchid=8483 | archive-url=https://web.archive.org/web/20110706005148/http://www.tate.org.uk/servlet/ViewWork?cgroupid=999999961&workid=21640&searchid=8483 | archive-date=6 July 2011 | url-status=dead | access-date=6 November 2022}}</ref> A well-known work by Man Ray is ''Gift'' (1921), which is an iron with nails sticking out from its flat underside, thus rendering it useless.<ref>{{cite web | title= Gift (1921)| website=Man Ray Photo | url=http://www.manray-photo.com/catalog/product_info.php?cPath=30&products_id=157&osCsid=d49650ee1a772ead1f06e8b878e83e9a  | access-date=6 November 2022}}</ref> [[Jose de Creeft]] began making large-scale assemblages in [[Paris]], such as ''Picador'' (1925), made of scrap metal, rubber and other materials.{{citation needed|date=November 2022}}

The combination of several found objects is a type of readymade sometimes known as an [[Assemblage (art)|assemblage]]. Another such example is Marcel Duchamp's ''[[Why Not Sneeze, Rose Sélavy?]]'', consisting of a small birdcage containing a thermometer, cuttlebone, and 151 marble cubes resembling [[sugar cube]]s.

By the time of the Surrealist Exhibition of Objects in 1936 a whole range of sub-classifications had been devised—including found objects, ready-made objects, perturbed objects, mathematical objects, natural objects, interpreted natural objects, incorporated natural objects, Oceanic objects, American objects and Surrealist objects. At this time Surrealist leader, [[André Breton]], defined readymades as "manufactured objects raised to the dignity of works of art through the choice of the artist".

In the 1960s, found objects were present in both the [[Fluxus]] movement and in [[pop art]]. [[Joseph Beuys]] exhibited modified found objects; examples include rocks with a hole in them stuffed with fur and fat, a van with sledges trailing behind it, and a rusty girder.

In 1973, [[Michael Craig-Martin]] claimed of his work ''[[An Oak Tree]]'', "It's not a symbol. I have changed the physical substance of the glass of water into that of an oak tree. I didn't change its appearance. The actual oak tree is physically present, but in the form of a glass of water."<ref>[https://web.archive.org/web/20090301093722/http://www.independent.co.uk/opinion/commentators/theres-no-need-to-be-afraid-of-the-present-625001.html "There's No Need to be Afraid of the Present"], ''[[The Independent]]'', 25 June 2001</ref>
