Today in Heritage History, 1824, Joseph Aspdin patents his invention, Portland cement, in Yorkshire, England. Noticeably absent from the patent party celebration was Aspdin’s competitor, Samuel Blinkerstone.

The two had been involved for years in a fierce and bitter competition to be the first to patent and market the new cement formula. Of special historical note however was that the first concrete pile for the foundation of the new London Bridge was laid earlier that same year with London agreeing to allow Aspdins to “test” his new product.
