[[Léon Creux]] first patented a scroll compressor in 1905 in France and the US.<ref>{{Cite patent |inventor-last=Creux |inventor-first=Léon |inventorlink=Léon Creux |title=Rotary Engine |country=US |number=801182 |pubdate=1905-10-03 }}</ref> Creux invented the compressor as a [[Rotary engine|rotary]] [[steam engine]] concept, but the metal casting technology of the period was not sufficiently advanced to construct a working prototype, since a scroll compressor demands very tight tolerances to function effectively. In the 1905 patent, Creux defines a co-orbiting or spinning reversible steam expander driven by a fixed radius crank on a single shaft.<ref>{{cite web |last1=Bush |first1=James W. |last2=Beagle |first2=Wayne P. |title=Co-Orbiting Scroll Design and Operational Characteristics |work=Purdue e-Pubs |date=1994 |url=https://docs.lib.purdue.edu/cgi/viewcontent.cgi?referer=https://www.google.com/&httpsredir=1&article=1977&context=icec |access-date=June 3, 2019 |archive-date=April 11, 2021 |archive-url=https://web.archive.org/web/20210411150320/https://docs.lib.purdue.edu/cgi/viewcontent.cgi?referer=https%3A%2F%2Fwww.google.com%2F&httpsredir=1&article=1977&context=icec |url-status=live }}</ref> However, the scroll expander engine could not overcome the machining hurdles of radial compliance inherent to achieving efficiency in scroll operation that would not be adequately addressed until the works of Niels Young in 1975.<ref>{{cite patent |inventor-last=Young |inventor-first=Niels O. |country=US |number=3874827 |title=Positive Displacement Scroll Apparatus With Axial Radially Compliant Scroll Member |pubdate=1975-04-01 }}</ref> The first practical scroll compressors did not appear on the market until after [[World War II]], when higher-precision machine tools enabled their construction.
