Thatcher studied chemistry at Somerville College, Oxford, and worked briefly as a research chemist, before becoming a barrister. She was elected Member of Parliament for Finchley in 1959. Edward Heath appointed her Secretary of State for Education and Science in his 1970–1974 government. In 1975, she defeated Heath in the Conservative Party leadership election to become Leader of the Opposition, the first woman to lead a major political party in the United Kingdom. On becoming prime minister after winning the 1979 general election, Thatcher introduced a series of economic policies intended to reverse high inflation and Britain's struggles in the wake of the Winter of Discontent and an oncoming recession. Her political philosophy and economic policies emphasised deregulation (particularly of the financial sector), the privatisation of state-owned companies, and reducing the power and influence of trade unions. Her popularity in her first years in office waned amid recession and rising unemployment, until victory in the 1982 Falklands War and the recovering economy brought a resurgence of support, resulting in her landslide re-election in 1983. She survived an assassination attempt by the Provisional IRA in the 1984 Brighton hotel bombing and achieved a political victory against the National Union of Mineworkers in the 1984–85 miners' strike.
