Focal developers

[piticu]

Can someone indicate an authoritative bibliographic source for Focal developers (like the one it can be found in Jacobson's Developing, formula No 16 or 99)? Thank you guys

Kurt Jacobson himself was the chemist & source of most Focal Formulae, along with LA Mannheim he was one of Focal's key writers right from Andor Kraszna-Kraus founding the company in 1937/8. All three had trained & worked in Germany before emigrating - escaping Hitler's Germany.

I should have them in other Jaconson/Mannheim books, I have the Focal Book of Formulae somewhere back in the UK which I bought in the late 1960's. May have scans from this book here, I'll look over the next couple of days.

So, all the "focal" developers are somehow related to the present days "Focal Press" of Elsevier? That's very interesting piece of info. Thanks Ian!
