Korah was born in London and educated there at convent schools, although was evacuated to the countryside and during the wartime years.
[2] While she was called to the bar in 1954,[1] she focussed on academia, completing a PhD on trade control at UCL.
[1][2] She was instrumental in shifting the legal, formalistic view of the European Commission (now DG COMP) to pioneering economic analysis through constant correspondence, education, conferences and engagement.
[2][5] Important to this were her classes jointly taught with René Joliet at the College of Europe, who later became a judge at the European Court of Justice.
In the 1990s, particularly through the "new wave" block exemptions on vertical agreements and new guidelines on merger control and competition enforcement priorities, the European Commission's thinking began to shift towards the arguments of Korah and Joliet.
