Do you mean he didn’t write the lectures he gave to students? I know the books weren’t put together by him and were substantially edited, but I thought the original lectures as delivered by him were either all or largely his work.
I once worked through part of the first volume of his lectures in the published book while listening to the recordings of him partly out of curiosity to see how much the original lectures as he gave them matched the ones which were compiled and published in written form (which I already knew was something not done by him). I came away feeling impressed one could either stick so closely to some lecture notes when lecturing and/or put together a written work which so closely matched a spoken one without coming across as being a transcript. It’s quite the accomplishment and one which I felt was a credit to everyone involved.
Yah, I was saying the volumes.

Leighton deserves the credit for this. Feynman did share his notes, but Feynman's notes are.. an adventure.. to work through.

It's pretty clear he also used the recordings of the lectures themselves. Otherwise there'd be a much bigger difference between the lectures as presented in the books and the audio recordings[1] of him actually giving the lectures. Leighton deserves a lot of credit, but the lectures Feynman gave were substantially similar enough that it's absurd not to act as though he didn't co-author them.

I don't doubt his notes would be, however they also used the audio recordings of and took notes during the lectures themselves for the books. I'm not sure how much they relied on Feynman's notes themselves though. It's been about 15 years since I last read and listened to them together, but I recall the experience of the combined activity being that the book was surprisingly close to being a transcript of what he said (including references to figures which the books reproduced).
This is why I thought it was impressive that the book didn't read like a transcript on its own. I rarely encountered professors who gave such well-structured lectures, but it seems like something Feynman could not only give prepared lectures in this way, but could do this off the cuff as well.

I'm sorry that it's difficult to convey tone on the internet. My intent was to highlight that absurdity that seemed to be present in the comment that I replied to-- Feynman only came up with the physics and gave the lectures, but didn't actually "write the book" is not much of a gotcha as far as the accomplishment goes.
It doesn't take away from Feynman, but it maybe adds a lot to each of the Leightons that they could capture such a range of ideas and Feynman's tone so well without simply repeating things verbatim in that transcript style.

Yes, this is one of the areas of significant challenges in reproduction. So Leighton definitely deserves a whole lot of respect for producing the work, from audio recordings, a few spare photographs, and notes. Even more impressive is what the Goodsteins did with the "Lost Lecture" to recreate the figures from just a few pages of surviving notes that looked like this:

(And it seems Feynman gave this 60 minute lecture quickly wandering between history, geometrical ideas, and dynamics-- that still seems well organized-- with these few pages of sparse notes).
