Nope. OSS and the Brits had suppressed STEN and Delisle carbines in WWII, along with High Standard .22's. Probably others I'm forgetting.
Hiram Maxim designed the first practical "silencer" during or before WWI. I'm not sure if they were used then, but I believe they were.
I'll defer to the experts. I only have a general knowledge of this subject.
