Albert Einstein | Autograph card signed, to Attilo Palatini, on Palatini's refinement to General Relativity, 16 January 1920

Albert Einstein.

Autograph postcard signed, to Attilo Palatini, contragulating him on the beauty and clarity of his latest work (“Ihre Abhandlung „Deduzione“ ist ausserordentlich schön und durchsichtig…”), and suggesting that he also send an offprint to Jacob Grommer, in German, [Berlin], 16 January 1920, staining

The article by Palatini that is praised by Einstein in this card was ‘Deduzione invariantiva delle equazioni gravitazionali dal principio di Hamilton’ (1919). This paper provided an elegant insight into the use of tensors in General Relativity and was cited by Einstein in his 1923 article 'On the General Theory of Relativity'. Palatini was assistente in rational mechanics at the University of Padua.
