Brenner, von Neumann and Schrödinger

Erwin Schrödinger’s book, “What is Life”?, inspired many scientists like Crick, Watson and Perutz to go into molecular biology. While many of the details in the book were wrong, the book’s central message that the time was ripe for a concerted attack on the structure of the genes based on physical principles strongly resonated.

However, influence and importance are two things, and unfortunately the two aren’t always correlated. As Sydney Brenner recounts in detail here, the founding script for molecular biology should really have been John von Neumann’s 1948 talk at Caltech as part of the Hixon Symposium, titled “The General and Logical Theory of Automata“. In retrospect this talk was seminal and far-reaching. Brenner is one of the very few scientists who seems to have appreciated that von Neumann’s influence on biology was greater than Schrödinger’s and that von Neumann was right and Schrödinger wrong. Part of the reason was that while many biologists like Crick and Watson had read Schrödinger’s “What is Life?”, almost nobody had read von Neumann’s “General and Logical Theory of Automata”.
