lecturer at the university, see Paul Epstein to Einstein, 11 September 1919 (Vol. 9, Doc. 102).
Einstein had made a sarcastic remark contrasting the cleverness and the courage of his fellow
Jews (see Doc. 141).
Elia G. S. Michelstädter (1880–?) and his cousin Emilio Michelstädter (1892–1933) were both
born in Gorizia in northeastern Italy.
The Swiss Patent Office moved from the old postal office on the Outer Bollwerk, where Einstein
had last worked, to an office barrack established during World War I in the Spitalacker district in Bern.
Einstein and Besso had worked together at the patent office from 1904 to 1908.

147. From Arthur S. Eddington
[London/Cambridge,] 1921 June 12
Dear Professor Einstein
Here is the paper we were speaking about on Friday
Later on I shall be interested to hear whether it fulfils the favourable expecta-
tions you formed in our conversation about it. But I am sure you will be kept very
busy during your short stay in England; so do not trouble about it until you are more
You will I think be interested in the conclusion I come to in §12—that this work
is an extension, but is not in the slightest degree an emendation, of yours and that

Eddington 1921. This paper presents a generalization of Hermann Weyl’s unified field theory.
Einstein himself had been working on his own modification of Weyl’s theory discussed, e.g., in
On Friday Einstein had participated in the monthly meeting of the Royal Astronomical Society,
where he was greeted by its new president, Eddington.
Eddington claimed that his version of Weyl’s theory removed the dependence of metric intervals
ds on the past history of objects in spacetime, a feature of Weyl’s theory that was objectionable to
Einstein (see Einstein 1921e, Vol. 7, Doc. 54).
