It seems that the first conscious steps to formalize these matters as a separate area of (system-theoretic or mathematical) research were undertaken only as late as 1959, by KALMAN [1960b-c]. There have been, however, many scattered results before this time (see Section 12 for some historical comments and references), and one might confidently assert today that some of the main results have been discovered, more or less independently, in every country which has reached an advanced stage of ``development'' and it is certain that these same results will be rediscovered again in still more places as other countries progress on the road to development.},
