In his book Jon Gertner details the history of the Bell Labs , an industrial research lab created by AT&T in 1925. Well-funded by AT&T’s monopoly on telecommunication in the US, the researchers at Bell Labs worked under the unique combination of available capital, freedom to explore ideas, and a long time horizon for projects. This attracted many PhD graduates (at one point more than 1000) to join the Labs and subsequently make several breakthrough discoveries: vacuum tubes, transistors, solar cells, fibre optic communication, radar, communication satellites, deepsea cables, the laser, UNIX, C, and the development of information theory.

Gertner explores how the lab was set up (having many researchers from different departments in the same building and encouraging cross-department collaboration and serendipitous discovery) to achieve these inventions and whether innovation can be planned.

Another theme of the book is AT&T’s struggle with the US government to keep its monopoly on telecommunication. For many decades the government agreed to the monopoly because of the natural monopoly of long-distance communication lines, AT&T’s commitment to improve communication technology for its customers and its strategic importance during and after WW2 (they also famously guaranteed not to enter the computer market). This constant struggle reminded me of the situation with the US oil companies in Yergin’s The Prize where the US government faced a similar strategic dilemma (more competition vs. strategic and military importance).

Jon Gertner gave a talk about his book at a Google event.
