Correct me if I'm wrong (he says, reaching for his flame retardent
suit).  I was told that an Oblique font was just a normal font tilted
(by an algorithm) a certain number of degrees and an Italic font was
one that was re-designed (by hand) at that angle.

As a counter example, both Courier (not a serious font, I know) and
ITC Lubalin Graph have oblique versions and serifs.

A stroll through Adobe's font dictionaries may prove this.

You were told wrong; Ken is correct according to my professional designer
friends.

So why don't you post their names so none of us makes the mistake

Cute.

In the common usage of typographers [that I know] (those who design type)

	italic		is a slanted serif face
	oblique		is a slanted sans serif face

In the common usage of type typesetters [that I know] (those who place type)

	italic		is an originaly crafted slanted face
	oblique		is a non-slanted face skewed by machine

     Designers of what?  Hardware, software, home fashions...

In my previous posting I gave an example.  I guess Bryan chose to
ignore it.  ITC Lubalin Graph is a typeface designed by Herb Lubalin.
It HAS serifs.  Its slanted version is called OBLIQUE, not italic.
(If this is not painfully obvious, let me know and I'll expand it to a
small novella.)

Italic fonts are redesigned versions of the original fonts.  Look at
the little "a" in Times.  The roman version of this letter is not the
same as the italic version.  This is what I'm talking about. 

In general, serif-oblique fonts look funny.  This is due to varying
width strokes in Roman fonts.  So, the fonts are redesigned and they
become serif-italic fonts.  But in Lubalin Graph, the stroke width is
constant, so slanting the font does not make it look bad.  And that is
what is done to produce Lubalin-Oblique, an oblique font with serifs.
So, it is not true to say that italics are for serif fonts.

This information comes from two sources.  The instructor at my
PostScript class (one of Adobe's first twenty employees) and our lead
typographer in our publications and graphics department (35 years
experience; used to kern letters with a hacksaw.)  I consider both
of the people pretty reliable sources in the typesetting field.

I know I am probably going overboard on this issue, but I am annoyed by
people that spread misinformation as fact.  If you want to speculate,
go ahead, I'm all for it, just preface it with some kind of warning.

Not so fast.  An oblique or slant font is, indeed, a slanted version of a
"normal" roman font.  It can be slanted algorithmicly or by design, and it
can be sans or with serifs, but it is always made with the same basic letter
shapes as the roman version of the same font.

An italic font, on the other hand, has different letter shapes.  It more
closely resembles a hand-written script; notice especially the differences 
in "a" and "g" in most italic vs. roman fonts.  An italic font may or may not
exist for a serif or sans serif font.

However, *in*practice*, modern oblique fonts are almost always slanted 
by algorithm.  If you want the same shape, why do otherwise?  And italic 
fonts can never be done by algorithm.  So, for most practical purposes,
the original statement was correct.

Also, for most practical purposes (although this is a poorer generalization),
the original statement that started this thread is correct, too.  Although
the concepts are independent, serif body fonts almost always have italics,
and sanserif fonts almost never do (though their obliques are sometimes 
mis-called italic).  It is simply harder to create a distinctly different,
yet related, set of letter shapes without the serifs to work with.  And
since nobody in their right might sets entire documents in sanserif fonts,
it isn't as important to have real italics anyway.  (Plus, sanserif fonts
are supposed to look simple and uncluttered, and having multiple basic
shapes for each letter tends to work against this idea.)

There is actually quite a difference between obliqued sans serif typefaces
and true cut sans serif italics.
  You can easily spot this when comparing the rounds (uppercase 'O' for
example) of an obliqued with an italic version of the same face.
  Also, a few faces such as Gill Sans use different lowercase 'a's in their
roman and italic versions. 
  For a real standout example, look at Adobe Systems' Font and Function
catalog. Notice Futura Heavy Oblique. Doesn't the 'O' in the word Oblique
appear a bit off balance?

As has been pointed out repeatedly (stone sans italic, lucida italic)
there are sans serif italic fonts which are not just oblique.

As knuth explains in one of his early books, Italics are hundreds
of years old, while oblique faces are less than 100 years old.

And while it is true that more serif fonts have italic versions,
all this means is that more serif fonts have italic varsions.

Translation: the people that you know who design fonts are
not being entirely accurate

Sort of right. Although it's not just a case if being ``slanted''. An *italic*,
while it is also slanted, has flourishes which distinguish it from
the same character un-slanted.

As a pointer to tradition, the original "fonts" dating back before  Gutten-
berg were generally done with pens that did not exhibit the same line width
in all directions.  This includes reed/quill pens,  stone  chisels,  stylii
for tablets, etc.  Brush letters are a different story, however.

Anyway, when holding one of these anisotropic pens, the nib  was  generally
slanted  to  the  direction of the baseline of the text.  Take a fat, broad
magic marker, draw a circle, and study the widths of  various  portions  of
the resulting "character".

Typically, a roman hand uses a different nib angle  than  an  italic  hand.
But  since  hands  are  all  done  by individuals, distinguishing different
"fonts" requires a more generic  approach  than  just  minutiae.   One  key
difference  is  that  italic  was  intended to be written fast, which meant
lifting the pen less:  more  rounded  characters,  smaller  letters,  joins
between  letters  (replacing serifs), and fewer strokes (one reason a's ap-
pear different).  Slanting the whole letter was  also  characteristic.   Go
back  to  your  magic marker, and draw an oval slanted to the right (/, not
\).

Originally, typefaces where intended to imitate  formal  hands  and  italic
hands,  and  we can expect that italic fonts were designed by copying hand-
made text.  Later (19th and 20th century  in  particular),  font  designers
made  their decisions based on other criteria.  For computer fonts, ease of
generation is obviously important, so simple obliquing has become more com-
mon.

By the way, "roman" originally was "upper  case"  [capitals]  only  --  and
stone  cutting  was a dominant force in its design, since the Roman culture
was much into permanent records.  I believe was tablets were also very com-
mon, but I don't know as much about Roman pens and/or brushes.

Uncials were an early (Christian era) attempt to speed up  the  handwritten
Roman letters, and contain capitals only.

If you've read this far, thanks.  References can be found in good calligra-
phy  texts, and Disney has a short on calligraphy narrated by John Houseman
(narrated the "old-fashioned way"?); it shows up on the Disney  Channel  as
filler, occasionally.  Also, the Western [American?] Italic Handwriting So-
ciety publishes journals and other information that may apply.

As a fun, readable historical reference on the history of letters and the
influence of tools on letter shapes, I would suggest *The 26 Letters* by
the late (alas) Oscar Ogg.  I'd forgotten about it, even though it's what
started me on calligraphy, until I saw a copy of the second edition, being
sold for cheap (remaindered?) at a local book store.
