can her act as both possessive pronoun and object pronoun?

Agatha Christie's travels with her archaeologist husband inspired her to write several mystery novels; travelers to Egypt can still stay at the Old Cataract Hotel, the model for the hotel in one of Christie's most famous books.

Possessive pronoun: her
Object pronoun: her

Note, her can have only one function. Either it's a possessive pronoun or it's an object pronoun.

Additional note, the possessive pronoun her is also known as a possessive adjective.

Thanks Soup!:)

Just to clarify myself more: In the second option( 'Because her husband..'), her is again possessive pronoun, right? How can we distinguish objective form and possessive form?

If there is a preposition after a her, then that her is in Objective form.. Am i correct?

Right. Moreover, the entire phrase her husband functions as the subject of the verb was here:

Ex: Because her husband was an archaeologist, ... .

The possessive form takes an object, whereas the objective form does not:

Possessive form: Because of her husband
Objective form: Because of her
