What Happened in 1955 With AI? The Year AI Got Its Name
Short answer: In 1955, John McCarthy and three other researchers wrote the proposal that first used the term "artificial intelligence." Later that year, Allen Newell, Herbert Simon and Cliff Shaw started building Logic Theorist, often called the first AI program. In other words, 1955 is the year AI got its name and its first real piece of software.
The 1955 Dartmouth proposal: AI gets a name
On August 31, 1955, four researchers sent a funding proposal to the Rockefeller Foundation:
- John McCarthy (Dartmouth College)
- Marvin Minsky (Harvard)
- Nathaniel Rochester (IBM)
- Claude Shannon (Bell Labs)
The document was titled "A Proposal for the Dartmouth Summer Research Project on Artificial Intelligence." It is the first known use of the phrase "artificial intelligence."
Its core idea still sounds modern:
Every aspect of learning or any other feature of intelligence can in principle be so precisely described that a machine can be made to simulate it.
The workshop itself took place in the summer of 1956 at Dartmouth College. That is why some sources say AI was "born" in 1956, while others point to 1955. Both are right: the name came in 1955, the field formally started in 1956.
Logic Theorist: the first AI program
In late 1955, Allen Newell, Herbert A. Simon and J. C. (Cliff) Shaw began work on Logic Theorist. It was designed to prove mathematical theorems the way a person would, by searching for a chain of logical steps.
When it was finished, Logic Theorist proved 38 of the first 52 theorems in chapter 2 of Whitehead and Russell's Principia Mathematica, and found a new, more elegant proof for at least one of them. Many historians call it the first true artificial intelligence program.

Why is everyone searching "what happened in 1955 with AI" right now?
Searches for this phrase went from almost nothing to a sudden spike on October 16, 2026. The trigger was not a history lesson. It was the Tesla Roadster.
On October 14, the day before the new Roadster's livestream reveal, Elon Musk shared a teaser on X with the words "Timing is everything." The teaser's "where we are going" line sounded a lot like Back to the Future, and fans quickly connected the dots: in the film, Marty McFly travels back to November 5, 1955 in a DeLorean, and the DeLorean famously flies in the sequel. The theory was that the Roadster would "fly" too. Tesla never said the timing was intentional; it stayed a fan theory.
A viral reaction clip on X, captioned "Timing is EVERYTHING…", spread the joke further. It never explains the reference, so people searched for it, and many added "AI" because of the Musk connection.
Two things worth knowing if you landed here from that clip:
- The real AI answer is the Dartmouth proposal above. The 1955 date works for both the movie and for AI history, which is exactly why the joke caught on.
- Not every "flying Tesla" video is real. AI-generated clips of flying cars were circulating before the reveal, so check the source before you share one.
Some people also search "what happened in 1995 with AI." The year in the joke is 1955, not 1995.
FAQ
Who coined the term artificial intelligence? John McCarthy, in the August 31, 1955 Dartmouth proposal he co-wrote with Marvin Minsky, Nathaniel Rochester and Claude Shannon.
Was AI invented in 1955 or 1956? The term was coined in 1955. The Dartmouth workshop that launched AI as a field was held in 1956.
What was the first AI program? Logic Theorist, created by Allen Newell, Herbert Simon and Cliff Shaw, begun in late 1955 and demonstrated in 1956.
What does 1955 have to do with the Tesla Roadster? Fans read Elon Musk's "Timing is everything" Roadster teaser as a Back to the Future reference, and 1955 is the year Marty McFly travels to in the film. Tesla did not confirm it.
What year did Marty McFly go back to in Back to the Future? November 5, 1955.
