Chancellor's Chair

Hi, can you anyone help me with "chancellor's chair"? Here is some context:
"She is the Chancellor's Chair and Professor of Marketing at the A. Gary Anderson Graduate School of Management".
I understand what a Chancellor is at a university. A chancellor is a kind of head of the university, but what is "Chancellor's chair'?
Thank you.

She holds that post. She is the Chancellor.

Okay, Cotty, thank you so much.
