Henry Bessemer patents a bottom-blown acid process for melting low-carbon iron. Ushers in the era of cheap, large tonnage steel, thereby enabling massive progress in transportation, building construction, and general industrialization.

A word about the original artwork: It was created by TMS’s David Rasel, who drew stylistic inspiration from the etchings in Georgius Agricola’s De Re Metallica. David’s mix of anachronism, whimsy, and technical/historical artistic license adds a memorable stamp to the proceedings.
