Is Peter C. Schultz Jewish?

Jews like to claim that the person who invented the particular optical fibre cable (not fibre optic cable in general) used for modern telecommunications – Peter C. Schultz – is jewish, (1) but this appears to be utter nonsense in that Schultz was born in 1942 in Brooklyn to a German-American father and a Czech-American mother. (2)

I can find absolutely no references whatsoever to Schultz having any jewish ancestry at all and even when Schultz talks about working with Israelis; there are no references whatsoever to any shared jewish heritage, which would be decidedly odd if Schultz was in fact jewish as jews like to claim. (3)

This fatuous claim seems to derive from the fact that Schultz can sometimes be an Ashkenazi jewish surname, but it is actually a common German/Dutch surname derived from the term ‘Schultheiß’ meaning ‘village headman’ or ‘sheriff’. (4)

If Peter Schultz is indeed jewish I can find absolutely no evidence of him mentioning it just jews claiming that he is without any evidence!
