Yes, along with Volt (V) for Allesandro Volta, Amp (A) for Andre'-Marie Ampere, Farad (F) for Micheal Faraday, Hery (H) for Joeph Henry and Ohm (Greek symbol Omega) for George Simon Ohm.
We really should have named something more prominant after Nikola Tesla if you ask me (but nobody did). A unified unit of motor power (instead of HP or kW) would have been more appropriate than a magnetic flux measurement (T) of 1 Wb per square meter. A Weber (Wb), of course comes from Wilhelm Eduard Weber.
The only term we accept abbreviated with a lower case letter is a Joule, (J or j), named after James Prescot Joule. I have no idea why the lower case is considered acceptable, but it is.
I actually did an entire term paper on the etymology of electrical terminology and got an A on it. Now it rattles around in my head uselessly until I can answer that kind of question or need to win a bar bet.
Cheers!

Not that there is any ambiguity, but j is too much like j, as in root(-1).
The conversation with the mathematicians (including my wife) usually goes something like this:
"Why don't you use i for the square root of minus one, like everyone else does?"
"Because i is for current."
"Why don't you use C for current?"
"Because that is for capacitance."
There seems to be no argument with that one.

William

k2panman,
weh3 is correct, k as in kilo is always supposed to be lower case, although it is very common to see it misrepresented as upper case. Upper case K is the abbreviation for Degrees Kelvin (and Karat, the gold content in jewelry). Unfortunately, when the computer industry adopted the representation of 1024 bytes to be "1000 bytes", they mistakenly used an upper case K, so now we are stuck with Kb as a term for kilobytes, but technically that has always been incorrect. It should have been kb.
At some point when the vast majority does something wrong, we often change the definition of right!

Fortunately, the byte is NOT an SI unit.
As for joules, the symbol is an upper-case "J." see:
The spelled out unit is lower-case, except for the "degree Celsius."

Actually in common usage 1 Kb is 1024 bits, not bytes. (128 Bytes).
we mostly use a upercase B when we mean bytes - 8 Kb is 1KB.
Needless to say, this is mixed up more than a few times.
C is for coulomb, a unit of charge, while capacitance is farhad (F)

quark, you are right that the abbreviation is capitalized (L), but you should not have capitalized the word liter.
