Little known fact: Neal McCurdy is the inventor of the Steady-Cam that's now a standard piece of kit in Hollywood. Neal was an engineer at Panavision and one night was watching a slot car motor breaking-in while dangling by the lead wires. He realized this was a cheap and simple gyro and designed the Steady-Cam from this. That next year Panavision was being awarded the OSCAR for innovation and Neal was supposed to be the recipient.... but his boss said no, that he (the boss) was going to the OSCARs. Neal wasn't the most photogenic guy but this was BS (in my opinion... and Neal's too).... Neal left Panavision not long after this. If anyone has better info PLEASE post it here as all this was told to me sometime after Neal had left SoCal....
Hey Phil, Strange that this info' has turned up here in a Slot Car forum, again.
Whilst he may very well have worked at Panavision and worked on and created Panavisions (Later) version of the Steadicam™, called the 'Panaglide', the actual Steadicam™, was invented and created by Garrett Brown, whilst working for Cinema Products (acquired & owned by Tiffen, since 2000) and was introduced and first used in 1975. https://en.wikipedia.../wiki/Steadicam

Panavision, being as they are and with the Cinema World ALL wanting to use the Steadicam, obviously wanted their own unit, so obviously set about designing one, which obviously Neal McCurdy must have worked on (eventually appearing some time in 1978), but saying that I am unsure of the Slot Car Motor 'Gyro' thing, as to my knowledge, (as with ALL versions of the Steadicam), they are Mechanical devices, not electro or electro-mechanical devices,.. there are NO Gyro's in use in the System.
You, the Operator and 'Wearer' provide ALL the Stability and the Steadicam, in effect, acts as an Extra 'Arm' with a Camera mounted to it.
Having been involved with the original units here in Australia, way back when I worked for the Cinema Products agents and having tried and used it myself, wearing one, unless you were also tall and Fit like Garrett, was HARD and a lot of work and even IF you were like Garrett, still a damn good work-out LOL
The 'Panaglide' unit was from reports Not nearly as comfortable to wear and Most uses of it often had CP 'Bits & Bobs' added to help and whilst it did work, it had More to do with the stupidly Light camera Panavision built to work with it that allowed it to do so.
The 'Panaglide 'Arm', was initially a Gas Shock fitted unit (to avoid Patent infringement) and was to all intents and purposes, a disaster. The Spring version, was a huge improvement but brought the Threat of Lawsuits from Cinema Products and eventually, the Vest & Arm were discontinued, with CP eventually agreeing to Sell Vests & Arms to Panavision for Rental.
Please understand I in No Way wish to belittle your friend's possible achievements but, having been involved in the industry at the time and this incorrect information coming up here a 2nd time, I simply wanted to provide the correct information, for those so interested. 
Cheers
