Earlier Patents
According to recent historical studies, the Italian inventors Eugenio Barsanti and Felice Matteucci patented a first working efficient version of an internal combustion engine in 1854 in London (pt. Num. 1072). It is claimed that the Otto engine is in many parts at least inspired from this precedent invention, but, as yet there is no documentation of knowledge about the Italian engine by Otto. The concept of the four-stroke engine was also patented (October 26, 1860) by the Austrian Christian Reithmann for one year and by the French Alphonse Beau de Rochas (January 16, 1862).

Famous quotes containing the word earlier:
“If in the earlier part of the century, middle-class children suffered from overattentive mothers, from being “mother’s only accomplishment,” today’s children may suffer from an underestimation of their needs. Our idea of what a child needs in each case reflects what parents need. The child’s needs are thus a cultural football in an economic and marital game.”
—Arlie Hochschild (20th century)
