Patrick Bell (12 May 1799 – 22 April 1869) was a Church of Scotland minister and inventor.
Born in the rural parish of Auchterhouse in Angus, Scotland, into a farming family, Bell chose to study divinity at the University of St Andrews.
Bell invented the reaping machine while working on his father's farm.
On May 3, 1831, a patent was issued in the United States to William Manning for the reaper of essentially the same design.
McCormick with his brothers mass-produced the machines and developed what became the International Harvester Company.
