Good point! Weren't relays the _very_first_ gain element?
the first electrical one
before (artificial) electricity there were mechanical gain devices like capstans
(the tension on the rope is multiplied by the modulus of friction and
some (exponential?) expression involving the number of turns)
but the first device with gain was probably the goad applied to a
beast of burden
