Well, I won't try to make you believe this, I will just tell you who
told me the story: Commodore Grace Hopper!  Well, she was there!
She was running that computer!  She did a lot of firsts!  I am not
going to tell her she is wrong!

The Oxford English Dictionary ( second edition ) quotes the use of "bug" as
"A defect or fault in a machine, plan, or the like" as early as 1889.  
Interestingly, it seems Thomas Edison may have coined the term:

     1889 Pall Mall Gaz. 11 Mar. 1/1 Mr. Edison, I was informed, had been
    up the two previous nights discovering `a bug' in his phonograph-an
    expression for solving a difficulty, and implying that some imaginary
    insect has secreted itself inside and is causing all the trouble.

Page 401 of Robert Blissmer's "Computer Annual: An Introduction to Information
Systems 1985-1986" (John Wiley & Sons) has a photograph of a 1945 log book page
for the Mark II with a largish moth taped to it.  The entry reads "Relay #70,
panel F, (moth) in relay, first actual case of bug being found".

This would lend credence to the story, but also suggests the term was already
in use at the time.

My understanding was that the term "bug" came from telephony, in which the
buzzing noises heard on bad lines was jokingly attributed to bugs buzzing
in the lines.  Maybe this, in turn, comes from the use in audio recording
technology cited by the OED -- namely, bugs making buzzing sounds on shoddy
recordings.

The 1945 log-book was a good joke since they actually *found* a real live
(rather, dead) bug that was causing the problem.  Hacker humor.

-Johnny Bug

	The moth-in-the-relay story was told in the first person by Grace
Murray Hopper, and the moth itself is on display in the logbook, wherever
it is kept at present.  She has told this story many times, in many
forums, including, I believe, the book "A History of Computing in the
Twentieth Century".

	The term "bug" was used before World War II for a defect or
problem in a mechanical device -- it is just that this is the first
documented _computer_ bug!

This reminds me of the time we found a Xerox Dandelion (1108 hardware
running LISP) dead due to a mouse that had gotten itself decapitated in
the power supply fan. Just think, if events had occured in a different
order we might refer to programs as having "mice".

One day we found that our 2-kilowatt transmitter had died because a
large spider had crawled into the final cavity and shorted out the
high voltage.  The computer controlling the transmitter had correctly
shut it down, but couldn't tell us that it had a bug....

The technician's remark upon finding the carbonized spider was "no
wonder it doesn't work: the chief engineer died!"

I'm told (I wasn't there) that the Bates Linear Accelerator in Middleton
Mass. was brought down (yes, the entire facility) by a stray cat which
managed to touch both terminals on the 10 MW (that's MEGAwatts folks)
primary transformer.  Supposedly it was quite a mess and took several
days to get everything back up again.

Anyone know the details?

I guess being a packrat has its uses.  I'm looking at a much-xeroxed page
from "The Laboratory <unreadable>", U.S. Naval Weapons Lab, Dahlgren VA.
Vol 45 no 36, but date unreadable.  Given the 1947 date and the 26 years
quoted in the caption this must have been published circa 1973 or so.

Those who don't want to see this, please skip this posting...

DO YOU KNOW THE ORIGIN OF THE WORD "DE-BUG"?
BILL BURKE IS THE OWNER OF THE ORIGINAL COMPUTER BUG.

In 1946 and 1947, Bill Burke, Head of the Computer Operations Branch (KOO)
and Ed Culhan, KEE, were at Harvard constructing the Aiken Relay Calculator,
more commonly refered to as MARK II.  Named after Professor Howard Aiken,
Head of Harvard's Computation Laboratory, the system operated with several
thousand electrical [sic] mechanical relays.  (Ralph, A. Niemann, Head of 
the Warfare Analysis Department, was one of the first civilian programmers
hired at the University to work on MARK II.)

In September 1947, the programmer and the engineers were having difficulty
getting a program to run.  After much exploration and much head scratching,
a moth was found trapped inside one of the relay cases of the calculator.
It had been beaten to death by the triggering of the relay.  The bug was
enshrined in the machine's log with Scotch tape and now resides in Bill
Burke's desk drawer in C-107, K Department.

For the record -- the moth removed from MARK II is the origin of the word
"debugging" and it is owned by NWL, and not displayed in the Smithsonian,
as has been reported, and it was removed from the Aiken Relay Calculator.

I might as well add my two cents, so here it is. My understanding of the word
bug is that it was used in the early 1800 during the first analytical engines.
Probably even before that, think about wooden ships and bugs (insects) in the
wood during building. This last part is not fact, just a thought.

I heard Grace Hopper give a talk a few years ago at a Heath Users' Group
convention. She told this story.

It was a long time ago... there's a first time for anything... but remember,
it wasn't just *any* relay, it was one in a computer...

    The First Bug

    Grace Murray Hopper, Captain, USNR
    NAVDAC
    Washington DC 20374

In the summer of 1945 we were building Mark II; we had to build it in an awful
rush -- it was wartime -- out of components we could get our hands on. We were
working in a World War I temporary building. It was a hot summer and there was
no air conditioning, so all the windows were open. Mark II stopped, and we
were trying to get her going. We finally found the relay that had failed.
Inside the relay -- and these were large relays -- was a moth that had been
beaten to death by the relay. We got a pair of tweezers. Very carefully we
took the moth out of the relay, put it in the logbook, and put scotch tape
over it (Figure 2).
    Now, Commander Howard Aiken had a habit of coming into the room and
saying, "Are you making any numbers?" We had to have an excuse when we weren't
making any numbers. From then on if we weren't making any numbers, we told him
that we were debugging the computer. To the best of my knowledge that's where
it started. I'm delighted to report that the first bug still exists; it is in
the Naval Museum at the Naval Surface Weapons Center in Dahlgren, Virginia.


Figure 2 shows a page of the Mark II log from September 9, 1945, including the
following entries:

    1100 Started Cosine Tape (Sine check)
    1525 Started Mult + Adder Test.
    1545    |moth|     Relay #70 Panel F
            |here|     (moth) in relay.
         First actual case of bug being found.
    1630 Arctangent started.
    1700 Closed down.

As pointed out in the v10n4 _Annals_, this should more correctly be called
"The First Computer Bug," since the meaning of the word "bug" is at least a
hundred years older. An 1878 letter from Thomas Alva Edison to Theodore Puskas
includes the passage "...then difficulties arise -- this thing gives out and
then that -- 'Bugs' -- as such little faults and difficulties are called..."

Grace Murray Hopper (Madame COBOL) is the source of that story.  Somewhere
around here, there used to be photocopy of a photo of the actual log page,
with moth, but it has disappeared.  Adm. Hopper believe that was the source
of the term "bug", but others have noted that "bug" was used to describe
problems in transatlantic phone cables sometime before that.

To interject another reference into this discussion, the following
is from the online Oxford English Dictionary (2nd ed.) as one
of the definitions of "bug":

  1889 Pall Mall Gaz. 11 Mar. 1/1 Mr. Edison, I was informed, had been
up the two previous nights discovering `a bug' in his phonograph-an
expression for solving a difficulty, and implying that some imaginary

I've seen the moth. It's in the Smithsonian.

I doubt if it was the first use of the word "bug" in this context.

Anyone know anything about the story about the vast capacitors used
for the Russian fusion torus project? Seems they had to carry such huge
voltages that the plates were a metre apart. Some guy walked between
them and...it took them a while to work out where this huge pile of dust
came from.

I have a 1-page summary of what is described in Steve'e posting, along with a
picture of the logbook page, that I evidently tore out of a _Reader's Digest_
many years back.  I have it pinned above my terminal.  At least it makes me

I'd just like to point out in connection with the 'first bug' story (and I too
have seen a photo of the notebook entry, complete with dead moth) that the
tone in which the story is told STRONGLY suggests that the term 'bug' was
already being used at the time the bug actually got caught in the relay.  That's
why people were so amused.
