Well, hopefully someone, someday might be thankful for the info on Joseph the concrete chap, so at least my time wasn't entirely wasted.
As for your chap, you have given very limited info, firstly saying you have a photo of something you think they invented, then saying you have a device bearing their name. Maybe if you share the photo and/or describe the device and what purpose it may have been for, someone will be able to better direct you.
