Catholic monks in Europe developed the modern music notation we know today, which included notating rests. Gregorian chant, which preceded this, did not have a notation for a rest.
I find myself using rests quite a bit playing solo
My point was that the critical role of rhythmic figures , for example beams, flags, ties, dots, rests
Is of great value to us bassists. The article linked does not address their development explicitly.
If that development can be traced to single person (which is unlikely,) They deserve a shout -out!
