Unrecognized Legends of Chess

I remember an opponent of mine downing four pints of Guiness and beating me in a well played league game once. I suppose he is a legend...I was impressed by his drinking and OTB play...

Alfred Lenton of Leicester, England, as a schoolboy he had time to stop playing the game he was playing with his son Philip in the back of their shop, reset their board and let me play him (whilst tsk tsking me lol). He was a master and a grand fellow! I would be about 11 or 12 at the time.

Nice

Milan Vukcevich. He was a GM of Chess Composition and is widely considered the second greatest problem composer of all time. His OTB results were impressive -- Yugoslav junior champion, drew a match with Bent Larsen, tied for first in the 1969 US Open, and took third place in the 1975 US Championship, for example -- but his main devotion was to his work in science, which severely limited his opportunities to play in tournaments. His work was of high enough quality that he was nominated for a Nobel Prize in chemistry.
Who do you think is an underrated chess legend?
