The world ash tree of the computer hardware industry… crystalline silicon from 1854.

The element silicon best represents the digital era of the mid 20th century to the present; without its crystalline form, there would be no computers (or this blog). Although it was first prepared in pure amorphous (powder) form around 1823[cite][/cite] by Berzelius, it was not until 1854 that Henri Sainte-Claire Deville made it in crystalline form, using metallic aluminium to isolate it. He described it [cite][/cite] as having a “metallic luster”.
