Michael Mosley, Cassie Newland and Mark Miodownik from the BBC series 'The Genius of Invention' describe the scientific achievements of Nicklaus Otto, Karl Benz and Henry Ford. Prior to this, the steam locomotive had started a revolution. Richard Trevithickâs design had a boiler but this was removed to make the internal combustion engine. The German inventor Nicklaus Otto developed the first four-stroke engine in 1876. This could not be developed until kerosene, diesel and petrol were used in place of coal. Karl Benz then developed the worldâs first car using Ottoâs design.
