 Last week, we had the pleasure of presenting Dr. Herman Horn, the node electronic scientist, in the first of three lectures on hi-fi. Last week, we had such wonderful hi-fi demonstrations as the mating call of the aardvark, Luella Parsons putting catsup on a clam sandwich at the Brown Derby. Goodness knows what fascinating experience is in store for us tonight. And here he is, that man about electrons, Dr. Herman Horn.
