Cressida Hogg has been named chairman of developer Land Securities – making her one of just six women to chair a blue-chip firm.
The mother of three will succeed Dame Alison Carnwath, 65, in July. She joined the board as a non-executive director four years ago.
Hogg previously worked at JP Morgan and 3i before managing £16billion at the Canada Pension Fund Investment Board.
She is married to Henry Legge, brother of William, the 10th Earl of Dartmouth.
