On what date was the 'first public radio broadcast?' We are looking for the first radio broadcast before a public audience, not the first National Public Radio (NPR) broadcast.

Earliest one I can find is December 24, 1906, made by Reginald Fessenden of Brant Rock, Massachusetts.

Reginald Fessenden (1866-1932) conceives of "heterodyning" to simplify and improve radio receivers, though the principle wasn't of real use until De Forest's invention of the triode. (Two radio frequencies are beat together to give a single "intermediate" frequency.) He is first to broadcast speech and music, in 1906.
