I think the source of the attribution to Ingalls is this paper:

The Smalltalk-76 Programming System - Design and Implementation
Daniel H. H. Ingalls

# Efficient Message Handling
# It should be obvious that to carry the message sending metaphor down into

# non-uniformity.

It is possible that Deutsch said it earlier, of course.
