Without reading the linked paper: Huber's loss was introduced by Huber in 1964 in the context of estimating a one-dimensional location of a distribution. In this context, the mean (average) is the estimator optimising L2-loss, and the median is the estimator optimising L1-loss. The mean is very vulnerable to extreme outliers.
