Date of birth unknown; died Apr. 22, 1778, in Nottingham. English inventor.

Hargreaves worked as a weaver in the town of Blackburn. In 1762 he constructed an improved carding machine. In 1765, Hargreaves invented a spinning mule that he called a jenny in honor of his daughter, and on June 22, 1770, he obtained a patent on the machine. Owing to the simplicity of its design and the low cost of its manufacture, Hargreaves’ machine was used widely.
