Antonio Magliabechi
Italian librarian, scholar and bibliophile.
Eighteen of the letters that Leeuwenhoek wrote to Magliabechi have survived. In addition, Leeuwenhoek dedicated Arcana Naturae Detecta to him. The best discussion of these letters is in Rijkberk's 1937 article (Dutch only).
The Rijnberk article from 1937 lists all of the known, though not preserved, letters from Magliabechi to Leeuwenhoek.
