We have a Nitsche archive and a couple of pages from the Complete Cut and Engraved Glass of Corning which may be of interest. I've attached a scan---including a picture from a private collection of Mr. and Mrs. Joseph Nitsche (1900).
One interesting part of the archive is the work order book, which contains small sketches of the pieces they worked on, the price, customer, etc. For more details please have a look at the archival finding aid (https://archivesspace.cmog.org/repositories/3/resources/18). There are some photos of glassware but none of the man himself. If you'd like to view the archive, though, please contact our archivist, Mary Anne Hamblen at hamblenma@cmog.org.
