David Singmaster
David Breyer Singmaster (Ferguson, dicembre 1939 – 13 febbraio 2023) è stato un matematico statunitense, per anni professore di matematica presso la London South Bank University di Londra. Singmaster possedeva una grande collezione di rompicapi meccanici e di libri sui rompicapi, e si descriveva come un metagrobologo. Divenne noto per essere stato uno dei primi promotori del cubo di Rubik. Il suo libro, Notes on Rubik's "Magic Cube", iniziato nel 1979 e pubblicato nel 1981, ha rappresentato la prima analisi matematica del rompicapo e conteneva uno dei primi metodi di risoluzione ad essere stati pubblicati; nel libro è stata sviluppata anche quella che è divenuta nota come notazione di Singmaster, una notazione usata per registrare le mosse compiute sul cubo di Rubik e che oggi rappresenta il metodo convenzionale utilizzato in tutto il mondo.
