I'm not sure how long the "Canadian Encyclopedia Online" has been around but I stumbled across it on Thursday and found a slew of very famous and well know broadcasting types that are highlighted in it.

Among them:

Allan Slaight, who nearly became a professional magician:

"He loved to impress friends and family with his sleight-of-hand and mentalist tricks. He started performing when he was eight years old, charging staff at the local bank where his grandfather was the manager $2 to see his show. For a brief moment in his 20s, Slaight considered doing magic for a living. Instead, he made it a lifelong hobby."

Imagine what might have been had his radio career disappeared like a rabbit in a hat.

And that's just a few of more than 160 pages under the search parameter of "radio." Nothing groundbreaking here but the photos are interesting and there's enough trivia to keep it interesting.
