History
The term standard deviation was first used in writing by Karl Pearson in 1894, following his use of it in lectures. This was as a replacement for earlier alternative names for the same idea: for example, Gauss used mean error. It may be worth noting in passing that the mean error is mathematically distinct from the standard deviation.
