Notable Contributions To The United States
David Rittenhouse made many breakthroughs during his life, which were great contributions to the U.S. During the first part of his career he was a surveyor for Great Britain, and later served in the Pennsylvania government. His 1763–1764 survey of the Delaware-Pennsylvania border was a 12-mile circle about the Court House in New Castle, Delaware, to define the northern border of Delaware. Rittenhouse's work was so precise and well-documented that it was incorporated without modification into Charles Mason and Jeremiah Dixon's survey of the Pennsylvania-Maryland border.
Later Rittenhouse helped establish the boundaries of several other states and commonwealths both before and after the Independence, including the boundaries between New Jersey, New York and Pennsylvania. In 1763 Mason and Dixon began a survey of the Pennsylvania-Maryland border, but this work was interrupted in 1767. In 1784 Rittenhouse and Andrew Ellicott completed this survey of the Mason-Dixon line to the southwest corner of Pennsylvania. When Rittenhouse's work as a surveyor ended, he resumed his scientific interests.

“What lies behind facts like these: that so recently one could not have said Scott was not perfect without earning at least sorrowful disapproval; that a year after the Gang of Four were perfect, they were villains; that in the fifties in the United States a nothing-man called McCarthy was able to intimidate and terrorise sane and sensible people, but that in the sixties young people summoned before similar committees simply laughed.”

“Every notable advance in technique or organization has to be paid for, and in most cases the debit is more or less equivalent to the credit. Except of course when its more than equivalent, as it has been with universal education, for example, or wireless, or these damned aeroplanes. In which case, of course, your progress is a step backwards and downwards.”
—Aldous Huxley (18941963)
