Historical Note on Sequence of Dudeney Numbers

The earliest known appearance of this result is from Claude Séraphin Moret-Blanc in $1879$, although exactly where this was published is still to be identified.

Henry Ernest Dudeney subsequently published it in one of his own collections.

As a result, a number which equals the sum of the digits of its cube is now called a Dudeney number.

It continues to crop up occasionally in publications devoted to recreational mathematics.
