Florence Gertrude Horsbrugh, Baroness Horsbrugh, GBE, PC (13 October 1889 – 6 December 1969) was a Scottish Unionist Party and Conservative Party politician.
The historian Kenneth Baxter has argued "in her day...
[she] was arguably the best known woman MP in the UK".
and that she was "arguably the most successful female Conservative parliamentarian until Margaret Thatcher".
