Supreme Athletes:
Everyone knows that Justice Byron White was a noted professional football player; but now I learn from a reader that when Chief Justice John Marshall was a young lieutenant during the Revolutionary War, he was known for his "athletic prowess in footraces and jumping contests" and was supposedly able to "leap over obstacles six feet high." (See Joseph Ellis, His Excellency 199 (2004).) The latter assertion strikes me as pretty improbable, but I pass it along for whatever it's worth . . . .
in 1912 the official WR for men's high jumpe was 2.00m (~6'6").
So, 6' ca. 1776 would seem to me to be exceptional, perhaps WR level. I mean, 6" in 125years, as medecine and nutrition improves, would seem to be very reasonable...
Think of vaulting over a wall by jumping and pushing off with your hands. Also, I seem to recall that an 8th grader in my junior high school in the 1960s could high jump 6 feet, so this story does not seem implausible to me if Marshall could use his hands to get lift.
Weren't people much smaller in the eighteenth century than they are today? I remember visiting museums exhibiting child-sized Revolutionary War uniforms, docents droning on about poor nutrition, disease, ignorance of hygiene...
I presume that Marshall was a member of the upper class, and would have fared better than the soldiers whose gear was on display. In any case, I don't see how a four-foot-something athelete would be able to jump over a six-foot obstacle, regardless of physical condition. Thoughts?
As for Marshall I am pretty sure he was over 6 feet tall just like his cousin Jefferson.
High jump technique in the United States has changed several times over the last century. Whatever Marshall was using was probably much more inefficient than modern techniques.
