All done without a theory:
There was no theory that preceded the transistor, it was patched-on later.
"The old quantum theory was a collection of results from the years 1900-1925 which predate modern quantum mechanics."
http://en.wikipedia.org/wiki/Old_quantum_theory
What this means is that when the first transistors arrived, quantum physics did not exist in any form recognisable today. It also coincided with the "Golden Age"(for rynner).
It's somewhat paradoxical when we consider that there was more by way of inventiveness during this period than there is today. Even more so if we ponder the fact that we have more scientists now than ever before in history.
This is just absolute and total nonsense.
What this means is that when
Julius Edgar Lilienfeld applied for his first patents for a device similar to a transistor, quantum theory had started to assume something like the form we know it today. Lilienfeld was amongst those many scientists working towards a modern theory of electronics, at the time.

Career
Well worth a read. Lilienfeld made the theoretical leap, based on his work on the electronic field effect, but it took several decades before the theory and the materials were advanced enough, to bring his ideas to fruition. This is the way things usually work.

You need to do more homework on this:
Lilienfeld's patent was for a field-effect transistor and Shockley applied for a patent but was turned down because his was also was a field-effect transistor(FET). Lilienfeld's transistor was not an
"FET-like transistor", it was an
FET, hence no patent for Shockley.
Walter Brattain and John Bardeen were the ones who built the point-contact transistor...

Shockley believed that since he had given the initial direction the idea for the transistor was wholly his. Shockley began a major campaign with the company's lawyers to patent the transistor exclusively under his own name. He called Bardeen and Brattain separately into his office and explained what he was doing. Brattain shouted at him: "There's more than enough glory in this for everybody!" Bardeen said nothing, but began to fume silently. The rift had begun.
It's fascinating and you can read it all at:
http://www.pbs.org/transistor/album1/addlbios/egos.html
Shockley having had his FET rejected, went on to claim sole ownership of the point contact transistor of Bardeen and Brattain. His only justification being that he was the gaffer.
But Wiki still gives him the credit:
Shockley co-invented the transistor, for which all three were awarded the 1956 Nobel Prize in Physics.
http://en.wikipedia.org/wiki/William_Shockley
The Nobel was awarded to Shockley after having played no part in the development of the point contact transistor by Bardeen and Brattain. The potential he saw was that he could get a Nobel prize for someone else's work having failed in an attempt to steal the FET from Lilienfeld.
The exact nature of Shockley's contributions to the development of the transistor remains a subject of controversy, as does the question of how much (if any) credit he should be given for its invention... Shockley's treatment of Bardeen and Brattain eventually prompted both men to break away from Bell Labs, and severed any good relations between himself and his former colleagues.

There is also an interesting letter on the same page that describes Shockley's contribution as development rather than invention.
The rivision makes Shockley a hero, but the history makes him a scoundrel.
