It all depends on how you define "Computer". There were relay machines in the 1930's and mechanical versions possibly before that. The modern definition is electronic, has an electronic stored program, no relays, wheels or drums of rotating capacitors. This rules out both ENIAC and Colossus. Colossus ran before ENIAC, in 1944.

The first electronic, stored program machine was the Manchester Baby, at Manchester University, England. It first ran in June 1948. It was inspired by Max Newman (ex Bletchley Park) and Alan Turning, who first wrote down the design for such a machine in 1936, since called The Turing Machine. There is no doubt that the Americans were not far behind the UK.

Hi Charlie,
You can't let the facts get in the way of youtube (probably AI slop) rubbish.

Last time you asked how I was, I got back from my woodturning trip to Newark and am now in hospital with Campolybacter not sure how I got it. If you have never had it, you don't want it.

If you have never been, I can recommend a trip round IWM Duxford, most interesting.

Regards,
Bob

Yikes Bob! Google says: "Campylobacter is most commonly contracted by eating raw or undercooked poultry, unpasteurized milk, or contaminated water". How did you get it? No one of those fast-food joints in down-town Newark is it?

Take care and get well soon. We can't do without you on the forum.

With respect to "The first computer", ENIAC takes it every time so what's the point of chasing the truth? It seems that if you say something often enough then that is then TRUTH. ChatGPT says:

First electronic digital computing machine: Atanasoff–Berry Computer (1939)
First programmable electronic digital computer: Colossus (1943)
First general-purpose electronic digital computer: ENIAC (1945)

But ABC had the capacitor mechanical drum, so it doesn't count.
Colossus wasn't programmable in the true sense.
ENIAC wasn't programmable in the same way either.

Strange that Manchester Baby (that was programmable) doesn't get a look-in.

Take care.

Hi,
And then there's Donald Trump's "Truth" ;D  ;D

Funny how ChatGPT show the American ones as the first which shows it is not intelligent and only knows the crap that it is fed in.

Hopefully not offended anyone, just my warped sense of humour.

Hi Charlie,
I have a couple of ideas, but probably my own packed lunch for the journey :-(

Have you asked ChatGPT where the Manchester baby come in the list?

Good idea! Here's what he/she/it says:

"Year                 Computer                                  Key significance
1939–1942   Atanasoff–Berry Computer       Early electronic digital computer (not programmable)
1943–1944   Colossus                                    First programmable electronic digital computer (special-purpose)
1945           ENIAC                                    First general-purpose electronic digital computer (programmed manually with cables/switches)
1948           Manchester Baby                   First stored-program computer to run a program
1949           Manchester Mark 1                   First practical stored-program computer"

Well that's a little bit better.  I suppose another part of the definition of "Computer" should be "..and it actually does something of general practical use..."

That set the cat amongst the pigeons.Just points out the problem  with AI.
As Charlie pointed out it comes down to what fits the definition of a computer.
Does it come down to a counting stick, a mechanical adding machine, a digital calculating machine or ....

It seems that the general consensus is that a computer in modern terms fits the definition that is recognisably an electronic digital stored-program computer. This was the Manchester Baby, a product of the University of Manchester that ran its first program on 21 June 1948. It met the criteria.

But if AI wants to make a counting stick the first then so be it.
 
Just to be clear, the University of Manchester is in Manchester, UK.

The world of science 'stands on the shoulders of giants' and the Manchester scientists' achievements do not take anything away from the many scientists in many countries that contributed knowledge to the success of the University of Manchester team. Like many 'inventions', progress in a field is incremental. Well done 'The Baby'.

John's modesty probably stopped him mentioning CSIRAC, Australia's valuable contribution. In my humble opinion the first three, truly general purpose, stored program, electronic, digital computers were:

The Manchester Baby, or Small-Scale Experimental Machine (SSEM), was the world's first stored-program computer, running its first program on June 21, 1948. Developed at the University of Manchester England. It ran a program to generate prime numbers. It proved the viability of Williams tube memory and led to the Manchester Mark I and the Ferranti Mark 1.

The EDSAC (Electronic Delay Storage Automatic Calculator) ran its first successful program on May 6, 1949, at Cambridge University, England. Led by Maurice Wilkes, the machine calculated and printed a table of squares, marking it as the first practical, full-scale stored-program computer to operate a regular computing service. [We have a rebuild of EDSAC at the National Museum of Computing, Bletchley]

Australia's first computer was the CSIRAC (Commonwealth Scientific and Industrial Research Automatic Computer), originally known as the CSIR Mark 1. It was designed in 1947, ran its first test program in November 1949, and was one of the world's first stored-program digital computers.

And again, in my opinion, the two individuals who had the biggest influence: Alan Turning and John Von Neuman (USA).

The Computer That Came First - And Was Erased.
I disagree.  The oldest computer is the one that is sitting between your ears, and it was erased throughout history with political, religious, psychological and chemical methods and substances amongst other erasure tools.
You even have a type of wi-fi / bluetooth built in that is far superior to the computer stuff you get today.
My forefathers were those who were persecuted through out Europe by the Christians, they fled to the Cape where the Cape Dutch Afrikaner continued the persecution which led to the Great Trek and a whole series of incidents that ended with the Boers having their country internationally recognized.
During this history there were many things that were achieved and done which is difficult to understand in the computerized and controlled (programmed) environment of today.
There were for instance of the Trekboers who made appointments to meet in an area, there were no maps, no roads, just a wilderness and they did not know of any beacons to look for.  They found each other.
Same during the War, with half a million British hunting the Boers, who was never caught because they somehow knew where and how to escape.  After the War's so called end, the Afrikaner military hunted and shot these Boer individuals who had certain abilities they did not understand.
Even today there are certain Boers who have certain talents which is difficult to explain considering the sh3t we live in.
It's like water witching, it is not recognized anywhere, but every one uses it to find water.  Because it works.
So what I'm saying is, you have the most amazing computer attached to yourself to your disposal.  It just depends if you choose to use it or not.
I saw my dad adding six figure amounts with cents by dragging his finger down a column and writing the total down.
Most underestimate themselves, you are far more capable than you think if you can peel off the stuck rubbish attached to the thinking part.

Do some research on remote viewing, if that has not been censored on the internet too.
