Grantham was the birthplace of the UK Prime Minister Margaret Thatcher. Isaac Newton was educated at the King's School. The town was the workplace of the UK's first warranted female police officer, Edith Smith in 1914. The UK's first running diesel engine was made there in 1892 and the first tractor in 1896.[citation needed] Thomas Paine worked there as an excise officer in the 1760s.[2] The villages of Manthorpe, Great Gonerby, Barrowby, Londonthorpe and Harlaxton form outlying suburbs of the town.
