Johnson was born on 19 June 1964 in the Upper East Side of Manhattan, New York City, to 23 year-old Stanley Johnson, an Englishman, then studying economics at Columbia University, and his 22-year-old wife of one year Charlotte Fawcett, an artist from a family of liberal intellectuals and a daughter of Sir James Fawcett, a barrister. Boris's parents had married in 1963, before moving to the US, where they lived opposite the Chelsea Hotel. In September 1964 they returned to England so that Charlotte could study at the University of Oxford ; during this time she lived with her son in Summertown, a suburb of Oxford, and in 1965 she gave birth to a daughter, Rachel. In July 1965 the family moved to Crouch End in North London, and in February 1966 they relocated to Washington, D. C. , where Stanley had gained employment with the World Bank. A third child, Leo, was born in September 1967. Stanley then gained employment with a policy panel on population control, and in June moved the family to Norwalk, Connecticut.
