Like many women of her generation, Dixon did not work outside the home, but was active in a number of voluntary organisations with a particular interest in expanding the range of activities women could engage with by right. She was a prominent member of the Irish Housewives Association, serving as chair from 1954-1955, and was selected as their candidate for the 1957 general election in Dublin South West. She was eliminated after the seventh count. Along with Kathleen Swanton, Dixon applied in 1954 for women to be volunteered on jury lists. Under the Juries Act of 1927, women who owned property could qualify and be liable for jury service, but were treated as exempt and would have to volunteer to serve. After making many application, these women's names were added to the list in 1955, but only after Dixon campaigning for years was she summoned, and even longer before she served. She was called on several occasions, but was turned down in the courtroom. She claimed that authorities thought women would be upset by some cases due to violence or sexual matters involved, and stated that the lack of women's toilet facilities in court buildings was a barrier for women's inclusion. Her contention was that the civil and legal rights of men and women were infringed by women not being allowed to serve on juries. It is believed that she was the first woman in Ireland to serve on a jury, during two high court cases in July 1957. The IHA continued to advocate for greater involvement of women in public life, convening a "women's dáil" at a Dublin hotel on 12 November 1972. The dáil brought together 180 prominent women, with Dixon selected as the "ceann comhairle". This alternative dáil discussed ways of improving women's status and social condition, but didn't have much influence on future legislation. Dixon was also active in the Girl Guides, serving in a number of roles, including area commissioner. She was engaged in local history, publishing a number of papers on the history of Dublin, and was a member of the Old Dublin Society for over 50 years, serving on its committee. She was a keen gardener, and taught gardening courses. Along with her husband, Dixon was a frequent correspondent to the letters page of The Irish Times. Dixon died on 16 March 2005 in Dublin, and her body was donated to the medical school in UCD.
