Sure, you've seen the handful of well-known photos of the Scotsman. But here's how George's son Ronald describes him in From a Northern Window: 

"In my earliest memory he was a man of forty; tall, with the build of an athlete, narrow-flanked and broad-shouldered; the hand and feet long and very finely formed; a head with brows and nose of great power; the hair and full beard as black as I have seen where there was no sheen of blue in it; and the eyes rather deep-set, of a blue liquid as southern sea-water at rest, keen as a northern sky in cloudless frost at mid-day--the only eyes I have known with always a spark and sometimes a flash in them."
