construction - Preposition followed by pronoun and noun phrase

I am reading Scrivener's Plain Introduction to textual analysis, written in 1874, and was surprised by the following construction :

It was presented to the University by Theodore Beza, for whom and his master Calvin the heads of that learned body then cherished a veneration.

I have never before read (that I can remember) a construction quite like this, where a preposition is followed by both a pronoun and by a noun phrase.

At first glance it seems wrong but the meaning is quite clear - the heads of the University had a veneration both for Beza and Calvin.

But I am still trying to get my head around what Frederick Scrivener has done here. Is he striking out on his own or would this be recognisable practice ?

The eighteenth and nineteenth centuries were extremely fond of long, complex sentences. No one dangled prepositions, yet most everyone had a profound sense of cadence. Scrivener isn't striking out into new stylistic territory; rather, he's more of an epigone.
