On December 19, 1871, Samuel L. Clemens (pen name Mark Twain) received a patent for an improvement in adjustable and detachable straps for garments.
This strap is widely used in bras now. It was his love of the ladies that probably led him to this invention. Twain also believed strongly in the value of the patent system.
