Iron and steel were as central to the Victorian age as the Internet is to ours. So it is fitting that Henry Bessemer, who revolutionised steel making and died 100 years ago this weekend, is well represented on the Internet. His autobiography has been put on the Web at http://www.history.rochester.edu/ehp-book/shb/. It’s a fascinating story. Bessemer was a prolific inventor, who met Napoleon III and was tried—and acquitted—for spying in Germany. Bessemer met the emperor while he was showing off his newly invented artillery shells to the French army. Although the army was interested in using the shells to replace cannonballs, Bessemer did not get the contract because the generals feared that their cast-iron guns would not be strong enough. This set Bessemer looking for a way to make iron stronger, and in 1856 he perfected the process that now bears his name, and the converter that made mass production of steel possible. An explanation of how the converter works and the dangers of the early trials can he found at http:
