Invention of the clapperboard/synch slate
Hi there,
I am researching the invention of the clapperboard (for my master thesis) and I am wondering of there is someone out there who knows more than wikipedia or the imdb note about it?

It must have happened sometime when the "talkies" began and the film industry adopted to the production of sound movies.
I would appreciate any hint or help!
Thanks a lot!
Hanne
