Totally off topic but worth a stab at it...
According to "Operating Systems Concepts" by Silberschatz and Galvin it
all depends on how you define "Operating System." The first operating
system for computers would have been a human being. The first software
O/S depends on your definition of O/S. As far as they are concerned, in
Chapter 21, if you were to define O/S as meaning 'the modern idea' of an
O/S, then it may (stress MAY) have been the Atlas O/S, designed at U
Manchester, England in the late 50's and early 60's. Also mentioned is
that the OS/360, with the note that "the longest line of O/S development
is undoubtedly that for IBM computers."
Also historically significant are the Turing computer in 1938, the EDSAC
in 1949 (another Turing with 1st library of subroutines), 1952 first
commercial compiler, 1954 has MATH_MATIC the 1st compiled language for the
UNIVAC I, Fortran developed at IBM, the first Assembler at IBM, 1957 DECs
Information Processing Language, 1959 COBOL, 1962 Time Sharing, 1965 Basic.
Anyway, a historical rant.....grab the book, it's great...

One advantage of talking to yourself is that you know at least somebody's
listening.
