The suggestion that Mileva actually co-authored some of Einstein's early papers was based largely on what is now generally agreed to have been a misunderstanding. In an obituary for Einstein in 1955, Abram Joffe wrote "In 1905, three articles appeared in the Annalen der Physik... The author of these articles, an unknown person at the time, was a bureaucrat at the Patent Office in Bern, Einstein-Marity (Marity – the maiden name of his wife, which by Swiss custom is added to the husband's family name)." Thus Joffe did not claim co-authorship, he merely stated that the papers were by an unknown individual, and that Marity was the maiden name of the author's wife, appended to the author's name by Swiss custom. Joffe's comment was later mis-quoted in a way that suggested co-authorship of the husband and wife. However, there is no such custom in Switzerland and Einstein never used the name "Einstein-Marity" for himself [۱].
