Don't ask me how I found this, but:

http://thesis.library.caltech.edu/2441/1/Knuth_de_1963.pdf

Anybody have any ideas how this was typeset?

It *looks* like it was written on a typewriter. But that obviously can't 
be true, because typewriters don't have Greek letters and other 
mathematical symbols on them. So... how?

(Incidentally, I bought a book on Galios Theory from Amazon. It was only 
£4 or something. But it's typeset exactly like this! Makes it quite hard 
to read complicated formulas...)

Probably with a typewriter with additional Greek letters. Academics used 
them. (Or at least typists did)

Welcome to the 20th C. The typeset would be hot metal. You can tell by 
the uneven baseline. Pick the book up and look at the page sideways. The 
bottom of the letters are all over the place. You might also find that 
the loops of "y" and "g" are filled in. This is typical of hot metal.

I looked at the page again and I don't think that it was typed and 
scanned. If you find a flaw in one of the letters the flaw should appear 
in all instances of that letter. If it was typed by a typewriter. This 
is not the case with that image. There is a lower case "m" that looks 
skewed and that is not a typewriter fault.
Since the theses is for a Doctoral degree it might have to have been 
published (by a printer) to count.
But anyway there are/were typewriters that used Greek fonts as well as 
the basic English ones.

I think though this was typed using a typewriter, although one of the 
more advanced ones of that time: electric, with ball-like type heads 
that you could switch for other type faces. They were expensive machines 
back then. See:

http://en.wikipedia.org/wiki/Typewriter

and especially the part about IBM Selectric. Those came on the market in 
1961, so that would explain your document.

IBM Selectric typewriter.

Does that mean you have to change the golfball for each individual 
character? (And is that how the subscripts and superscripts work?)

I presume the underlining is done by hand with a ruler.

No, the "golf ball" has an entire character set on it.

Nope.

There is some evidence in the scanned document that special symbols like 
greek letters were added later, after the bulk of the document had been 
typed already; some of those special characters appear to be drawn, 
while others appear to be typed.

So it's probably /not/ one of these:

http://blog.modernmechanix.com/mags/MechanixIllustrated/12-1958/double_keyboard.jpg


Sub- and superscript were of course done by moving the paper up or down 
manually by a detent(*), typing the letter, then moving the paper back.

(*On a typewriter, the cylinder would usually have detents at fractions 
of a nominal line feed; operating the carriage return lever would 
advance the paper by multiple such small steps at once, with the exact 
number configured via a lever. The cylinder could also be operated 
manually via a knob at either side.)

I suppose underline was achieved by overtyping with a special underline 
characters; IIRC common typewriters lacked such a special character, and 
you'd use the minus instead.

Some special characters were certainly achieved by overtyping as well, 
such as the not-equal sign (equal sign and slash) or the "end of proof" 
sign (opening and closing square brackets).

Now, I really am feeling old! I realise that whole generations are 
living now who do /not/ know what a typewriter looks like nor how it 
worked. Incredible and sad but that is progress ;-)

My father was a journalist so the typewriter was the centrepiece of his 
work and I played/used it too from my most tender years. I knew all the 
bells and whistles, and all the smart tricks you could do with them. 
Later, at university, I typed my reports on my own typewriter. And then, 
during the early years at the Geological Survey, we wrote all the drafts 
of our reports and books in the same way. You know where the expression 
"cut-and-glue" comes from? Exactly! Writing books was writing (by hand) 
-> typing -> emending with pen and and ink -> cutting -> glueing -> 
typing again, and again, and again. We also had a nice lady who would 
help with the typing of course, whose typing errors we had then to 
correct again with pen and ink, and so on... ;-)

The coming of text editors on a central main frame computer you could 
reach by /dialling/ a phone number on your phone then changed the world 
for ever for us...

No.  You just select a ball that has regular letters and math symbols. 
(each ball had 72 characters, IIRC.)

Super/subscript was done with a different lever or key that raised or 
lowered the key slightly.  Many typewriters - even the kiddie one I ah 
when I was but a wee lad - had that option.  and for those that didn't 
you simply rolled the sheet up or down using the big rollers at the 
back, and then put the sheet back in place to continue typing.

Now, before you say: "but that was a lot of work"  We were used to it as 
we had to do it whenever we needed to correct a mistake and apply 
white-out.

Probably.  You could return the carriage to the left (hence the name 
"carriage return" for \r) and type over the words that needed 
underlining with the underline symbol, as well, but if you needed to 
underline a big portion of the line, it was easier to use a black pen 
and a ruler.

I don't believe a single bit of it.  You're just pulling our leg.  Next 
thing you're going to tell us you had to stand up and walk to the tv to 
change the channel!

Sheesh! old folks with their made up stories to make us feel bad!

Ha! My lad! What do you know! I remember the days we had radio's with 
glowing lamps inside! And you had to turn a dial until - through the 
static - you could hear a /voice/ talking! /Music/ sometimes!

That was before we had television even... And they told wild tales of 
the past in those days too: about people taking a Hansom cab to get 
places, and horse-drawn tramways... phew!

I have heard stories that in antiquity you had to buy games in these
square-shaped disks. Square shaped disks! That doesn't make any sense.
That's like saying that wheels are square.

And seemingly they could only hold like a megabyte or so of data. Can
you believe that? That couldn't hold even one single HD jpeg image,
and that was supposed to hold an entire game? Hah.

For what it's worth, my parents had a typewriter. They never *used* it 
for anything (as far as I can tell), but my sister and I had endless fun 
playing with it.

...fun, that is, until you make a mistake. For typewriters offer no way 
of correcting a mistake, other than to retype the entire page from scratch.

Now that I think about it, it's kind of odd that I spent so much time 
playing with a typewriter, given that I hadn't learned to read or write 
yet...

Sheesh, kids these days. You used correction fluid or correction tape
to white out the mistake, and re-typed it over.

Well, the data were wood and/or cardboard so the megabyte was rapidly 
filled up.
