Thatcher's ashes were interred in the grounds of the Royal Hospital Chelsea, next to those of her husband.
Her birthplace was here, above a grocer's store owned by her father.
She studied chemistry at Somerville College, Oxford, and worked briefly as a research chemist, before becoming a barrister.
Her leadership was soon tested. In April 1982, Argentina invaded the Falkland Islands. Thatcher authorized and dispatched a naval task force to retake the islands. The military conflict lasted 10 weeks and ended with the surrender of the Argentine forces.
In 2008, Conservative Prime Minister David Cameron presented Thatcher with a lifetime achievement award at a 2008 Great Britons award ceremony.

LIFESTYLE Politicians
The first woman to become prime minister of the United Kingdom, Margaret Thatcher served three terms as premier, from 1979 to 1990. Throughout her tenure, the Conservative politician lambasted the Soviet Union, survived an audacious assassination attempt, implemented policies known as Thatcherism, and took on trade unions in often bitter and protracted industrial disputes. Not for nothing was she known as the "Iron Lady."
