(Babs) Ethel Greig Robertson (5 May 1902 – 4 December 1985) was a Scottish businesswoman and whisky brand investor.

She had two sisters, Agnes and Elpeth, and until the 1918 flu pandemic she had a brother who was the heir apparent to the family whisky business.

Her grandmother Agnes Heatley Robertson was one of the first Scottish women to attend university (in her middle age).

In 1946 Ethel cleverly manoevered control of the business to her and her sisters as they struggle to avoid a takeover bid by Samuel Bronfman of Seagrams.

[4] They also established The Robertson Trust, a registered charity under Scottish law, which owns all voting shares in Edrington.
