|Spouse(s)||Sir Rhys Rhys-Williams|
She began her career as private secretary to the Director of Training and Staff Duties at the Admiralty in 1918, becoming private secretary to the Parliamentary Secretary, Ministry of Transport, 1919–1920. She was working for Sir Rhys Rhys-Williams, 1st Baronet, and they were married in 1921. Subsequently she was often known as Lady Williams.
She contested the 1938 Pontypridd by-election as a Liberal National candidate. Her candidacy attracted popular attention because she decided to stand when her baby daughter was just 8 days old. As a supporter of the National Government she received the formal support of the local Conservative Association. In a two-way contest she polled 40% of the vote. From then on her political activities were in support of the official Liberal Party. In 1943 she became Honorary Secretary of the Women's Liberal Federation. In 1944 she became Chairman of the Publications and Publicity Committee of the Liberal Party, serving for two years. She was a member of the Liberal Party’s ruling Council.
Her ideas on income tax reform were published by the Liberal Party. She contested the 1945 general election as the Liberal Party candidate for Ilford North. She resigned after a disagreement on policy matters with her party's leaders.
Lady Juliet Rhys Williams was a member of the Beveridge Committee and unsuccessfully proposed a Basic Income in the form of a negative income tax, as an alternative to the main, insurance based recommendation of the Beveridge Report.
Lady Rhys-Williams was interested in film, and involved in the development of colour film, taking out a patent in 1930, with Sydney George Short.
