I was a little surprised when they called him "fat and gimlet eyed". That sure as heck wouldn't fly today.
"Dignified and alert"--would that do the trick? I've seen pictures of him. He was fat and gimlet-eyed. One of the things I like about old-school journalism is its lack of euphemism and circumlocution in the name of political correctness.
As to why Chornock was not described, I suggest that the reporter never met him, and did not have a picture on file. Pre-plane travel, pre-internet. No bias--or rather, from the WASP perspective of the time, both Catholic and Orthodox Slavs were essentially shifty foreigners. You wouldn't let your daughter marry one.
