om and Jerry is an American animated series of short films created in 1940
I loved Tom and Jerry growing up. Do you know who created the show?
The original creators were  by William Hanna and Joseph Barbera.
Interesting, how many voice actors did they have during the running of the show?
Probably none, since  Tom and Jerry, and many recurring characters, do not speak!
Ahh that makes a lot of sense, have you watched a lot of that show as well?
In its original run, Hanna and Barbera produced 115 "Tom and Jerry" shorts for Metro-Goldwyn-Mayer and I think I've seen them all.
