IMHO, these ideas were more clearly expressed by people like
Parnas and Liskov back in the 70's.  For instance:

  D. Parnas, "On the criteria to be used in decomposing systems into 
      modules," CACM, v15, Dec. 1972.

and more recently:

  B. Liskov and J. Guttag, _Abstraction_and_Specification_in_Program_
      _Development_, MIT Press and McGraw Hill, 1986.

Of course, the phrases "information hiding" and "ADT" don't sound 
as high-tech as "object-oriented" :-)  (Comments about polymorphism
and inheritance unnecessary, and flames to /dev/null.).
