The safety razor was initially developed by William S Henson as an improvement on the cut-throat which was being used at the time. The disposable blade was invented by Gillette. Initially he had experimented with glass blades, that failed, and moved on to metal.
I am not sure whether Gillette Shaving cream dulls blades, but I am fairly sure that any such stuff does. I stopped shaving with shaving cream about 20 years ago. I shave in the shower, using the tactile sense in my fingers to ensure that I get all whiskers and let water do what shaving cream does -- keep my whiskers wet so they can be easily cut off. After starting to shave in this way and ever since, my blades last just about five times longer than they used to. Shaving cream is a waste of money.
