Re: Look-ups requested in Rosenstein's The Unbroken Chain, newest edition #poland
As all my knowledge about Zeev Wolf Landau comes from the book The Unbroken Chain Vol 3, and there no mention is made of any Tiktin, I can unfortunately not help you any further.
I would suggest that your first port of call is to look through the indices of the 5 volumes of above book which have appeared till now. You can find them here:
Or hopefully someone else on this site will recognise the name. Send in a new request with the name Tiktin in the heading, as not everyone will see this.
