Identity of a Mathematician Mentioned in Euler I and several others are in the process of translating one of Euler's papers from Latin to English, in particular the one that the Euler Archive lists as E36. In it Euler proves the Chinese Remainder Theorem, but my question is this:
In Section 1, Euler refers to two (presumably mathematicians) named in Latin as Lahirii and Sauwerii. The Latin is as follows:

Ita quadratorum magicorum constructio iam pridem ab arithmeticis est tradita; qua autem cum esset insufficiens maiora ingenia Lahirii et Sauwerii ad perficiendum requisivit.

We are reasonably confident that Lahirii refers to Philippe de La Hire as he did in fact work on magic squares (quadratorum magicorum), but we have no clue as to the identity of Sauwerii and can find no mention of a mathematician named Sawyer who worked on magic squares.
Does anyone know who this might refer to?

There is also a reference to Sauveur in Sandifer's book, "The Early Mathematics of Leonhard Euler", in the chapter about E-36.
