Marc,

Thanks for your interesting points on Wanderslebs' life. Zeiss in the
thirties, under Wandersleb, was definitely ahead of Leitz in optical design
so Wandersleb must have been doing many things right. And Wandersleb too, of
course, has the right to make the occasional error. I feel that it's comic
though to see the man write an entire book to prove a point, the exact
contrary being demonstrated a little later.

Gerard Captijn.
