Okay, so I said I wouldn't repeat stuff that other people posted, but this is just too cool to pass up (and the geek in me loves it!). But I will put my own twist on it at the end, promise.
Hans Perk has posted a cool set of pictures of the original patent for what we today know as Circle Vision 360 (then Circarama).
The listed co-inventors are Ub Iwerks and Walt Disney.
I remember seeing my first Circle Vision movie when I was about 7 when my family and paternal grandparents traveled from Missouri to Southern California to visit Disneyland (that would have been the summer of 1979) and other destinations along the way (we went to Las Vegas, Universal, the Grand Canyon and others. A regular old road trip!).
Everybody in the family thought the movie experience was awesome until they put us on the back of a hook and ladder truck (that's the fire truck that has a guy steering in the back as well) going down Lombard Street I think it was in San Francisco. My grandmother got nauseous and had to sit down on the floor! The rest of us survived to tell the tale however.
Hans has another link to some very cool pictures of the old Circarama camera setup.
Unfortunately the current search engine at the US Patent and Trademark Office only goes back to 1975.
Regardless, for fun I tried searching on Disney as an author and came up with 75 patents for different types of transistors, MOSFET devices, etc. in which a 'Donald Disney' is the author or contributor. All stuff an electrical engineer (like me) would understand, but nothing related to the Disney company, and no easy link I can find to the Walt/Roy Disney family or company.
So then I searched on Iwerks and came up with 2 patents. Both include a 'Donald W. Iwerks' as an inventor (one he shares with others in 1979 when he worked for the Walt Disney Company, and the other which he shares with Walt Disney Imagineering legend Bob Gurr!).
Some of you may know more about Don Iwerks than me, but I admit despite the fact that Don is an Oscar winner and former Imagineer, I had no idea who he was!
I know of Leslie Iwerks, Ub's granddaughter, from her movies, but didn't know Donald. So after a little more searching I found this and this. Cool! So Don is Leslie's father and Don also has a brother named Dave who works in the industry as well (he worked at LEAST on Tron according to IMDB).
Anyhow, the short family tree lesson later I found something I didn't know, but that again many of you might have: that Don left Disney in 1986 and he started his own company Iwerks Entertainment.
According to the link, Don started Iwerks Entertainment around the idea that the:
. . . high-technology, cinematic attractions at Disneyland and Disney World were proven winners, convincing Don Iwerks that the attractions could stand on their own and attract lines of customers outside the borders of sprawling theme parks. Further, Iwerks reasoned, the high-technology attractions could draw even larger audiences if presented at more conveniently accessible locations than Disneyland and Disney World. . . Don Iwerks was convinced he could develop the world's premier location-based entertainment (LBE) company.'
(sound a little familiar to some of Jay Rasulo's current thoughts on the expansion of the Disney Parks & Resorts brand?)
Iwerks Entertainment had a respectable track record of success throughout the late 80's and 90's, had a successful IPO and traded on the NASDAQ, and even bought out their second highest competitor. At one point, according to this Los Angeles Times article, the stock traded at over $120 on a split adjusted basis.
Unfortunately, the company fell on hard economic and business times in the early part of this decade and in 2001 was acquired for only a little over $2 million according to the same LA Times article.
Today, Iwerks Entertainment and it's technology still live on as part of Toronto based SimEx - Iwerks, a leading company is 3-D and 4-D experiences and motion rides.
Maybe one of them is close to you?
