Having lived in Sweden and as this site is 'The Swedish Tiger' I cannot help but give a little background on this American-Swedish engineer. Besides inventing two heat engines and one of the first railroad engines his fame probably is greatest in the field of naval engineering.
John Ericsson did not invent the screw propeller, that honor belongs to the Scottish engineer Robert Wilson. Up to the moment of this 1827 invention the fastest method of powering a boat was by side paddles. Unfortunately Britains Admiralty ignored the invention. The screw propellor was patented by Ericsson in 1836 with the American Government taking full advantage of it.
In 1903, at Kittyhawk, NC., Orville and Wilbur Wright found another use for the propeller.
The famous, four hour, battle of the Union USS Monitor (foreground) and the Confederate CSS Virginia.So good were the Iron clads that neither ship could inflict serious damage on the other. These ships, and the battle, changed the course of Naval Warfare forever.
The photos depicts the inside of the turret of the Monitor. The turret, designed by Theodore Timby swivelled and, in the heat of battle, was like an oven inside. The remainder of the ship was designed by John Ericsson. He designed his ship to have the engine below the waterline, thus lessening the chance of it being hit by shellfire, a design first.
At only 23 he designed the steam engine, 'The Novelty', which raced against Robert Louis Stevenson's 'The Rocket' for a railway competition in 1829. The Rocket won, propelling Stevenson to instant fame, but Ericsson's time was to come.
