Durham and O'Reilly patented the mortarboard (graduation headwear).

Joseph Durham was a Catholic priest, while Edward O'Reilly was an inventor. They used fibreglass to increase the stiffness of this piece of "graduation gear."

Mortarboards are shaped like a square, perhaps to give them a scholarly appearance like a book or to represent the shape of a quad on the campus of England's Oxford University, where many graduation dress customs are believed to have originated. Typically, the mortarboard is worn with one corner facing forward, like a diamond.
