William Petty (1623 - 1687)


Petty was an advocate of data collection and quantitative enquiry in economics and other issues of state whose own exercises in ‘political arithmetic’ included an attempt to estimate national income and can be seen as early examples of applied econometrics.His will refers to a house in Tokenhouse Yard, Lothbury, now in the City of London, largely destroyed in the Great Fire of 1666. He died in his house in Piccadilly in central London opposite to the church of St James in that street.
