Nikolaus August Otto (1832-1891), German engineer. Otto invented or worked on several early internal combustion engines, including one in 1862 and the Otto-Langen engine of 1864. The most successful was the Otto Silent Engine (or Rings-Schumm engine) of 1876. Using in-cylinder compression and the principle of the Otto cycle, it forms the basis of modern car engines. This photograph is courtesy of the Otto Engine Company, Philadelphia, USA. It was published in 'The Epic of Industry' (1926), volume 5 of 'The Pageant of America: A Pictorial History of the United States'. This was a 15-volume series that commemorated 150 years since the founding of the USA in 1776.
