As everyone who knew Professor Herbert Kellogg during his or their careers agrees, he was the proverbial “perfect gentleman”. On top of that, he was a giant in his field and produced a great deal of seminal work, which is cited to this day. A clear sign of his greatness is that even those who did not have any direct interaction with him hold him in the highest esteem. The metallurgy profession has lost a distinguished member, which the entire community mourns.
