Answer 14

Don't forget in:
1800 Count Alessandro Volta invents the battery.
1858 Jean Lenoir invents an internal combustion engine.
1898 Rudolf Diesel receives patent #608,845 for an "internal combustion engine" the Diesel engine.
1885 Karl Benz invents the first practical automobile to be powered by an internal-combustion engine.

I believe that should cover the most important inventions.
Of that time period.
