Das Lemma ist nach Pavel Urysohn benannt und wurde von diesem 1925 veröffentlicht. Es wird vielfach benutzt, um stetige Funktionen mit gewissen Eigenschaften zu konstruieren. Urysohns lemma säger att ett topologiskt utrymme är normalt om och endast om två separata slutna uppsättningar kan separeras med en kontinuerlig funktion.
