For those who might be interested, I recommend
"History of Photography," by Joseph Maria Eder. First published in the early 1900's, it is still occasionally republished from time to time; my paperback edition was published in 1978.
The author was a contemporary of the companies and men who created the craft, art, and science of photography.

As such, he has a unique perspective to offer that is not seen in the usual 'History of Photography' books. He had great attention to detail and minutia, which is now lost to the ordinary historian, since he was there at the time and knew many of the persons involved personally. He has much to say about the Voigtlanders, from Friedrich Ritter von Voigtlander to Johann Friedrich to Peter Wilhelm Friedrich von Voigtlander. He speaks extensively about Josef Max Petzval (Hungarian, born to German parents). He invented the Petzval lens, and entrusted an optician, Peter Friedrich Voigtlander of Vienna to build it. Apparently, there some misunderstandings, and there were a number of disputes between them over the years.
As an interesting side-note, the sheer number of mathematical calculations necessary to compute the lens was such that Petzval solicited the aid of Archduke Ferdinand, who put several soldier-mathematicians under Petzval and his assistant Reisinger's command to do nothing but run calculations for the lens.
Another interesting side-note: the formula for the Petzval lens would have been lost to history; as both Petzval and Voigtlander, for various reasons, chose not publish same; but for the lawsuits between them required the original formula to be disclosed to the court, and hence to the public. It was from court records that others retrieved the formula after the patents had expired.
