Yes, you would be referring to Fritz Kreisler, who was a German born violinist and composer of the late 19th century and early 20th century, if I recall correctly. I doubt that a TV manufacturing company would name their brand after a famous classical music composer, but I could be wrong, I've heard of stranger things (like the Ford Edsel was named after one of Henry Ford's sons.)

Some years ago I was watching Kinescopes (on DVD) of an old 1940's TV show, it was live and they would interrupt from time to time to mention the sponsor, which in this case was Kreisler (pronounced Chrysler) Watch Bands, I have no idea if it was the same company.
