Historical Note on Wiener Formalization of Ordered Pair
The Wiener formalization of the ordered pair was devised by Norbert Wiener in $1914$.
According to Set Theory and the Continuum Problem by Raymond M. Smullyan and Melvin Fitting, this was the first such scheme for axiomatising the concept of the ordered pair.
