In 1911, Henry Phipps founded Bessemer Securities to reinvest the proceeds of his sale of Carnegie Steel for the benefit of his descendents. The start-up investment operations were spun out into Bessemer Venture Partners.

"…it is, nevertheless, impossible for me to convey any adequate idea of what were my feelings when I saw this incandescent mass rise slowly from the mould: the first large prism of cast malleable iron that the eye of man had ever rested on. This was no mere laboratory experiment." - Sir Henry Bessemer

In  1855, Sir Henry Bessemer demonstrated the process for making stronger steel more quickly and inexpensively than conventional methods. In 1874, Henry Phipps and Andrew Carnegie adopted this process in a startup mill at Carnegie Steel.
