Just a dumb guess on my part, I'll be the first to admit.
But it would tickle me to think maybe, maybe, maybe I'm right!
The guy started turning up examples of combinations of very high and very low redshift objects which were clearly connected and part and parcel of the same things (meaning that the standard interpretation of redshift to mean expansion is garbage) and for that he was given the heave-ho out of American observatories and then was picked up by the Max Planck Institute, sort of like the fairytale of the ugly duckling which turned out to be a swan...
