In case you're wondering who he is, exactly, I'll do a quick list of various shows he helped create.



Thunderbirds

Supercar

Stingray

Joe 90

Space 1999

Captain Scarlet

Fireball XL5

UF



Granted, the stuff may be seen as old now, since nobody really uses marionettes anymore, but honestly, tell me that you cannot be impressed by the Mobile Elevator Cars from Thunderbirds.



He passed away at the age of 83, in his sleep.

I loved those shows when I was younger! It is a sad loss.

A sad loss, but he appears to have been very fortunate in that he was quite old when he passed away peacefully in his sleep. A good way to go IMHO.
