Fuselage frame History??

Looking for any information anyone might have or references you might know of to the History of Fuselage Frames in boats. I am writing an article and would like to have some facts. About all I have found it is that is probably started in the early 50’s maybe late 40’s after the war, when cheap plywood became available. Past that I don’t have a lot more info.

You’ve probably already read this?

other forums
Been discussed on other forums, fuselage construction has been around for at least 110 years, probably somewhat longer.
