Ian Botham was the first player to score 5000 runs and take 300 Test wickets, and the first to score a century and take 10 wickets in the same Test match. ...
Nelson - the dreaded score of 111. When this total is reached, the superstitious custom is for the batting team off the pitch (and umpire David Shepherd) to take their feet off the ground. The name was coined in the mistaken belief that Nelson had one eye, one arm and one leg: in fact, he had two legs. (S).☺☺☺
Strictly speaking the first person to score 100 runs and take ten wickets in the same Test Match was
A.K. Davidson of Australia v West Indies in Brisbane in the 1960-61 series. He scored 44 and 80 = 128. and took
11 for 222. Source - Wisden. Botham`s effort was in 1979-80.
The answer I previously gave is clearly reported on the following website .. it is unusual for this site to give false information, but it appears that boaw has found conflicting evidence!
On the definition of a Nelson, I agree with my good friend sarumite in his choice of "eye" and "arm" - but not "leg" as the third component.
As I heard it, if Nelson were an octopus then he would have only seven tentacles! I shall go immediately to Google to check this important historical (hysterical?) fact.
