While "Fashion Merchandising" and "Modern Architecture" seem to be quite interesting as well as needed for a designer, I think that "Introduction to Horticulture" is quite a weird addition to the list. The same goes for "Economics of Commerical Aviation". How many designers that finish these courses can actually benefit from them? I hope they're something you can opt-in only if you're interested.

MZ, I think you're missing the point. Bierut was not saying that those are courses he would or could have done at design school, he's saying that when working as a designer, you have to have a broad knowledge in a range of fields, so you can understand and meet your clients' needs. Therefore you might have to know a bit about horticulture or aviation if you are dealing with clients in those fields.

As someone going into the field of design, this is one of the most attractive and interesting facets of the profession for me.

Also shows what we all know but tend to forget.
Those with different educations than yours are not ONLY educated in the specific topic that their title suggest.
Some of us tend to "narrow" our perception of a designer to "someone who has learned how to draw" just like people who learn that I'm an M.A. in film, media and rhetorics don't know that most of above courses would be a natural part of my education too.

The same is true of anyone with a good work ethic, regardless of the industry. No one works in a vacuum, and knowing more about your colleagues', vendors', and clients' industries only helps to make your work better.

It does make a nice argument for a budding designer attending a university, as opposed to a 'design school'

Designing is in fact a very small part of being a designer. My wife is a jewelry designer, but she has learned quite a bit about marketing, 'brand dna' (which I know is one of those buzzword phrases, but it's true; if you don't really try to know the brand inside and out, how do you design for it?), and always keeps her eyes open for what everyone else is doing in the fashion and luxury realms including clothing, jewelry, furniture, accessories, etc.

Design is an odd field, though. Much of it is very superficial, no matter what anyone says. A Tiffany setting engagement ring might be iconic, timeless, beautiful, etc, but it's still just a very expensive ring holding a very expensive diamond. And the ipod is much the same. What has it really done for my life beyond remove the clutter of cds in my car?

As a successful designer who didn't go to design school, I completely agree that a broad knowledge of many subjects is essential to success in the field. If you don't know about a client's business, you are obligated to learn as much as you can, either through conversations with the stakeholders in the company or through independent research (most often a combination of both).

A diamond ring is totally different than an iPod-- aesthetics are only a part of the reason people buy iPods. I also wouldn't underestimate the value of removing clutter from your life.

Here's a list of things I came up with that i've learned in my web design career so far. Some I learned a little about, some quite a lot:

Business & Franchises
Sales
Sociology
Investing (Stocks, Futures, Investment Trusts)
Real Estate & Mortgages
Filtration
Energy Conservation & Power Grids
Marketing
Product Design
Non-Western Religions
Government, Politics & Voting
Environment & Air Pollution
Automobiles & Automotive History
Transportation Networks
Tollway System
Phone & Computer Networks & Peripherals

Although I guess sales could be considered part of the job because you're always selling something to somebody.

haha you design geeks are so full of yourselves, really, i find it amusing. look at the most compelling services on the web today and look for the rennaisance man behind them. haven't found him yet? give you a hint, he was in computer science class when you wouldn't be caught dead there.

Piers, I agree completely. I haven't explained myself as I should have as that is what I was hinting to with the "opt-in" comment. Naturally having as much experience and knowledge is the best possible thing but I know a myriad of designers and not one of them ever did work for anyone related with an airline. That's probably because my country has only 1
:) Anyway, very interesting comments so far.
