Who wrote that?

Scientists are used to anonymous review, but not to anonymous publication.

Manuscripts submitted to scientific journals undergo peer review, which is usually anonymous, such that the authors do not learn the names of the reviewers. The editors know who the reviewers are, but the names of the reviewers are hidden from the authors (and usually also from the other reviewers).

Of course, when we read articles in scientific journals, the names of the authors are not hidden.

But.

In 1970, the prestigious journal Nature published, anonymously, an article entitled "Effects of Sexual Activity on Beard Growth in Man".
