Hi O-10 - thanks for reposting those links. It made me realize I had heard of Willie Ruff also in the context of Yale, but never put two and two together that this was the same jazz horn player. I haven't Googled him, so I don't know if he is still living. He certainly hasn't been at Yale in decades now.
The one clip that had him playing horn was quite short, just the Stompin at the Savoy tune. Fine rendition, as far as it goes, doesn't really show off much improvisational skill. I don't have any albums of his other than the one I mentioned where he is playing hymn tunes in a church. I'd love to hear more of him, to really check out what he could do. It's possible that he didn't improvise a whole lot - he certainly would have learned that skill later in his horn playing life, judging from the comments he makes to Gumbel.
He certainly wasn't the best out there in the New York jazz scene back in the day, though this should not be taken to mean he was not a good player. The best jazz hornist out there was Julius Watkins - I have a few albums of his that he did as leader, though usually he was a side man, as pretty much most jazz horn players are. Robert Northern was another, and even Gunther Schuller played quite a bit of jazz on the side back in the day when he wasn't in the pit at the Metropolitan Opera. All three of these men appeared with Miles Davis, at least two of them on Birth of the Cool. Julius Watkins records are worth seeking out, though they are very hard to find and usually very expensive, being Blue Notes. There is one he did for Philips called French Horns For My Lady, all Quincy Jones arrangements.
