Here I was just trying to give a reference to Hadamard's writings about the 
connection between continuity and computation. As Jesper Carlström mentioned 
to me offlist, one could also read your question as: what is the earliest 
connection between continuity and computation. In this case at least Brouwer 
seems to have been earlier: Beeson (p369) refers to a paper by Brouwer from 
1918, in the second paragraph of p160 of Brouwers collected works.

So depending on what you are looking for you might want to call it: the 
Brouwer principle, the Brouwer-Hadamard principle or the Hadamard principle.
