While Marconi believed code was transmitted through
ether, and marketed point-to-point communication, Fessenden understood
radio waves, and developed the first transmitter for voice.

Not so, Marconi fully understood the significance of waves
"When Heinrich Hertz, who discovered wireless waves, died in 1894, Righi
wrote an obituary that fired Marconi with the idea of deploying these waves
for 'wire-less' telegraphy. "So elementary, so simple in logic," he said
later. "
