Einstein can't be classed as witless
He claimed atoms were the littlest
When you did a bit of splitting-em-ness
Frighten everybody shitless

I think this begs for a definition of clever.
Most dictionary definitions link clever with intelligence.
Dirac was undoubtedly a genius (as measured conventionally) he apparently had an IQ somewhere around 190, I believe, but he was autistic. And when asked how he found his famous equation he said "I didn't talk to anyone"
But there are other forms of intelligence/cleverness, I would guess he might not have scored so high on divergent thinking.
But as you say by conventional measures Clever Bastard given Einstein's IQ was said to have been only 160!
For info 210 is the highest recorded - Kim Ung-yong

A story told of Dirac is that when he first met the young Richard Feynman who was a genius in his own right, at a conference, he said after a long silence, "I have an equation. Do you have one too?"
Yes, Dirac was on a different level to most of his peers.

Dirac was notoriously precise about his lectures. Victor Weisskopf used to tell the famous joke about Dirac’s answering questions after he’d given a lecture. One student said, “I don’t understand that second equation, Professor Dirac.” Dirac remained silent. “Aren’t you going to answer the question?” asked Weisskopf. “That was not a question, that was a statement,” said Dirac.

Going to see The Blockheads in July at a little local festival in my Somerset town. No, not Glasto.
I just hope they have a good frontman on the night.

So clever that his famous Delta function isn't actually a function.
Almost eveyone else with a famous function has one which IS a function.

Take the test (literally takes less than 4mins)
It claims to test your creative thinking (rather than your IQ)
Here is what it said about me and I ain't no genius.
"Your score is 89.25, higher than 95.39% of the people who have completed this task"
Bit of fun but proves nothing of course.

A function is a map between two sets, A and B, which assigns one and only one member of B to each member of A. (Members of A can share the same member of B).
The Dirac delta function ẟ is defined like this ∫f(x)ẟ(x-y)dx = f(y) for all "reasonable" functions f.
A naive interpretation of ẟ as a function from the real numbers to the extended real numbers (real numbers with two special elements, plus and minus infinity), with ẟ(0) = infinity and 0 elsewhere doesn't really work - as the usual varieties of integration are not changed by changing the value of a function at a single point, the defining equation would reduce to ∫f(x)ẟ(x-y)dx = ∫f(x)0dx = 0.
There's all sorts of complications involved in properly defining ẟ, some of which change if you change the meaning of "reasonable".
I can't claim to have studied this in detail, and I would have forgotten most of it by now, anyway

Well I can't claim any expertise in higher maths but is Wiki wrong when they characterise the Dirac delta function as a generalized function or distribution over the real numbers?
If it is wrong are you implying that Dirac is some kind of a fraud when even Einstein was befuddled over some of his work?
I believe Dirac proved through his work, the existence of antimatter?

Dirac was regarded by his friends and colleagues as unusual in character. In a 1926 letter to Paul Ehrenfest, Albert Einstein wrote of a Dirac paper, "I am toiling over Dirac. This balancing on the dizzying path between genius and madness is awful." In another letter concerning the Compton effect he wrote, "I don't understand the details of Dirac at all."[12]
