Earlier. Algol 68 already moved to call by reference. I paraphrase from page 182 183 Informal introduction to Algol68 (Lindsey / van der Meulen) " Algol 60 had something called Jensen's devise, using (or misusing) call-by-name. In algol 68 we use references only. " Then they give an example of how the effect of call-by-name of e.g. a real can be had by using a procedure that returns a a real. Basically a call-by-name is a procedure where the input parameters are obsured, as viewed from the algol 68 perspective.
