Timothy Leary was a Prof at Harvard along with Richard Alpert (Ram Dass)....
Yes, Duncan is a self-described hippie (see INC article) and I have seen many pics of the early crew at VC and can attest for hair at least to the shoulders and other such factors. They were "drop-outs" from society in the classic sense - having moved to backwoods VT and Backwood Colorado. Here's an article and my take on it and other stuff I've heard around it:

"The Vermont enclave Prickly Mountain was built as an antiestablishment utopia—and that’s what it still is."

Long story short, there is an enclave near Sugarbush in Northern Vt that become a gathering place for hippies - many of them highly educated college types from the Ivy League. A spirit of Utopia and "anything is possible" in housing and other design was fostered there - sort of an artists colony type of thing. Duncan and Murray were part of the Prickly Mountain Gang, and that is where the stove idea and even design originated.
Just to clear things up about colleges and hippies - remember, in the late 60's the colleges were the epicenter of a lot of the "movements" from the anti-war to the free speech and on and on. Hippies, at least the ones I knew, often had former lives as things like MIT graduates! Hippies were, in fact, largely from the middle and upper class educated families, as the poorer folks tended to be drafted and sent to Vietnam....and other reasons apply also. In other words, hippies were largely white, educated, etc.
(Wow, amazing how much gets lost over the years- we'll have to find some pics of Duncan sucking on a joint)
BTW, this goes for a lot of the stove industry as a whole - lots of hippies, back to the landers, etc....involved. In fact, I remember the first couple trade shows - a lot of long hairs and casual clothes. Then, in 1980, all of a sudden we noticed that the trade show was taken over by "suits" (salesmen) - most of us had never seen anyone in the industry wear a suit! It just was not done When I used to visit stove companies, you would see the owner welding or painting stoves....hair tied behind him, of course!
Many Folks might know that Kurt Rumens, President and Founder of Lopi (Travis Industries) was a drummer for a highly regarded rock and roll group....he has stories of being "this close" to being Aerosmith! But he fell into selling stoves....and then making them! A couple million stoves later, and Kurt is still very well known for a "rock and roll" attitude in the industry....
Speaking for myself and some others I know in the industry, we were coming of age in the late 70's - trying to find something to do which fit in with our ideals of a simpler life and energy independence, etc. - this is why I and many other entered the business.
So, while this does not apply to 100% of the industry, a LOT of original biz was related to dreamers like Duncan, Kurt and...to a lesser extent, storekeepers like myself.
