Apparently, the so-called random walk problem was set out by Karl Pearson in a letter to Nature in 1905 [1] [2]
"A man starts from a point O and walks l yards in a straight line; he then turns through any angle whatever and walks another l yards in a second straight line. He repeats this process n times. I require the probability that after these n stretches he is at a distance between r and r + dr from his starting point, O."
