Mark Dominus (also) blogs about misattributions ...

Continuing the list of misattributions further ....

Dirac delta function. In "The mathematical century" claims it was introduced by Heaviside. And apparenly, he was expelled from the royal academy of sceinces for this misdemeanour. People (his critics) seemed to have considered this not "formal", "rogourous" enough.

There is a also a nice PDF by V Balki (V Balakrishnan) of IIT-M on the topic. Now, that aricle states mathematica indicates a similar history. But it also states
The delta function seems to have made its first appearance in the early part of the 19th century, in the works of Poisson (1815), Fourier (1822), and Cauchy (1823,1827)
