Ron and Murray, My understanding is that the Loewe name is Jewish. Ludwig was a merchant turned sewing machine manufacturer turned major industrialist. I have been gathering scraps of data on Loewe manufacturing over the year in hopes of putting a small essay together. A brief history, that may not be preciely accurate but is close, can be found at the follwing link.

The traditional German Jewish pronounciation would be "Low eh". BUt people do tend to pronounce things the way they want to and there might be wide variation from area to area. For instance "Kerry" is often pronounced "meat head" in the red states.
