Not following the deduction--the 60 in Algol 60 refers to 1960. Simula was influenced by and implemented in Algol 60.

And in what respect does this contradict my statement? The paper appeared in 1973.

(By the way: Simula 67 was mostly influenced by Simula I; both Simula versions are an extension of Algol 60; with some minor exceptions Algol 60 is a subset of Simula 67 - as later Stroustrup did it with C and C++).
