If you are asking about the doctrine of the right to privacy, this doctrine was first created by the Supreme Court in the case of Griswold v. Connecticut.
There is, of course, no right to privacy that is explicitly mentioned in the Constitution. However, the Court held in Griswold that various parts of the Bill of Rights and the 14th Amendment combine to imply that there is a right to privacy. The Court ruled that other rights that are specifically protected in the Constitution (like the right to freedom of speech and the protection from warrantless searches) imply that people have a Constitutional right to privacy.
In this sense, then, the right to privacy originated with the Supreme Court in 1965.
