Although he was an accomplished [[differential geometry\|geometer]], he is best remembered today for two important contributions to [[general relativity]]. Together with [[Howard Percy Robertson\|H. P. Robertson]], they devised the well-known [[Robertson–Walker metric\|Robertson-Walker unit]] for the [[Friedmann–Lemaître–Robertson–Walker]] cosmological models, which are [[exact solutions in general relativity\|exact solutions]] of the Einstein field equation. Together with [[Enrico Fermi]], he introduced the notion of [[Fermi–Walker differentiation]].
