Summary This note “rediscovers” the original interpretation of kurtosis as an indicator of “a prominent peak and a prominent tail” on the density curve. A formal proof that such curves have indeed relatively high fourth moments is given. A comment is made concerning the recent decline of this correct classical interpretation.
