She was a teacher of English and Music, and the head of the Green Schools Committee at St. Tiernan's Community School in Dundrum for 15 years prior to being elected to the Dáil. She is married to Francis Noel Duffy, also a Green Party TD and they have three children. Catherine and Francis first meet in 1999 during a local election in their native Carrickmacross in County Monaghan where Catherine's brother Vincent P. Martin and Francis' father were both campaigning for office. Vincent is also a member of the Green Party. In June of 2020 Vincent became a senator upon the Green Party entering into government.
Political career
She joined the Green Party in 2007. In 2009 Vincent began a hiatus from politics and as a result Catherine was co-opted to Vincent's seat on the Monaghan County Council. Catherine in turn vacated the seat upon the death of the Martins' mother and co-opted it to local green party member Darcy Lonergan. She was elected as Deputy Leader of the Green Party in 2011 simultaneous to Eamon Ryan becoming leader. In 2014, she was elected to Dún Laoghaire–Rathdown County Council, and was elected to the Dáil in the 2016 general election, after receiving 4,122 first preference votes. She was the Green Party's Education Spokesperson. Martin was elected the first chair of The Irish Women's Parliamentary Caucus in November 2017, an organisation she spearheaded the creation of. In May 2020, following nominations from several councillors, she said that she would give 'serious consideration' into running for leadership of the Green Party in the 2020 Green Party leadership election. On 6 June, it was confirmed she would contest the leadership. Martin received 200 nominations for the contest, four times as many as was needed. Within the Green Party, Martin's candidacy is seen to represent the views of younger, more radical Green Party members who did not wish to enter into coalition with Fine Gael or Fianna Fáil, in contrast to the leadership of Eamon Ryan which is seen to represent the moderate "old guard" who are open to working with those parties. Despite this, Martin was the lead negotiator for the Green Party in the government formation talks with Fine Gael and Fianna Fáil, and after a deal was reached, Martin endorsed the deal and argued in its favour. It was noted at the time Martin's husband Francis Noel Duffy abstained from the vote on the deal, and later spoke out against the deal. Martin suggested that this was "part of a healthy debate" within the Green Party over the merits of the deal. Upon entering the government, Martin became Minister for Media, Tourism, Arts, Culture, Sport and the Gaeltacht, succeeding Josepha Madigan and Shane Ross. In July 2020, Ryan retained the leadership of the Green Party by narrowly defeating Martin by 994 votes to 946, a winning margin of 48 votes, in a postal ballot of party members.
