There were some remarkable comedians in the 50’s and certainly Sid Caesar was one. Today you don’t have as many and those you do have are not family friendly. Sid Caesar, Bob Hope, Victor Borge, Danny Kay, and Jackie Gleason all were capable of appealing to a broad audience and without vulgarity (at least in their TV programs).

I’ve seen Victor Borge perform live and there is no vulgarity to his act.
Ernie Kovacs was another from that era.
