Here is Dijkstra:
http://www.u.arizona.edu/~rubinson/copyright_violations/Go_To_Considered_Harmful.html

First statement:
| For a number of years I have been familiar with the observation that

And here is Hoare, not identical to Dijkstra but with similar areas of 
interest and similar views on correctness etc, very unambiguously
criticising exceptions:

| Ada has a plethora of features and notational conventions, many of them
| unnecessary and some of them, like exception handling, even
| dangerous.  Do not allow this language in its present state to be
| used in applications where reliability is critical
