After her time at Newnham College, Powell taught at
Queen's University Belfast starting in 1916 as deputy for Hugh Meredith, a professor of economics, before leaving in 1918 to go to
Victoria University of Manchester to work as an assistant lecturer in
political economy. In December 1919, the
Sex Disqualification (Removal) Act 1919 became law; one of its provisions allowed women to become
solicitors. Less than a month later, Powell became the first woman ever admitted to
Lincoln's Inn, one of the four
Inns of Court in
London. She was never called to the bar, instead continuing to teach and write about economics. When Powell's husband, physicist
Harold Roper Robinson, went to work at the
Cavendish Laboratory in
Cambridge in 1921, Powell moved with him and became director of studies in economics at her
alma mater,
Newnham College, Cambridge. It was during her time in this role at Newnham College that she published her most influential work,
Public Finance;
John Maynard Keynes provided the foreword for the work. Powell left her job at Newnham College and moved with her husband to
Edinburgh in 1923, to
Cardiff in 1926, then to
London in 1930, continuing her involvement in economics throughout this time. She worked as a lecturer at
Birkbeck College before eventually returning to Newnham College, where she was first a visiting lecture and then, in 1937, became the director of studies in economics, remaining in that position until her death in 1939. == References ==
