Francis Bacon was born in London on January 22, 1561. He studied at Cambridge, trained as a lawyer, served in Parliament, became Lord Chancellor. But his most lasting contribution was a process for discovering truth: systematic observation, hypothesis testing, reproducible results.
Before Bacon, knowledge came from authority. If Aristotle said something about nature, it was accepted for two thousand years. Bacon argued the opposite: don't trust ancient texts, trust evidence. Gather data, look for patterns, test hypotheses, refine based on results. This wasn't philosophy in the abstract. It was a workflow anyone could follow. You didn't need genius. You needed discipline and a willingness to be wrong.
The implications were enormous. If knowledge could be systematically generated, progress no longer depended on rare brilliant individuals. Teams could collaborate. Results could be verified. Mistakes could be corrected. Newton wouldn't have developed calculus without this framework. Neither would Darwin or Einstein.

Bacon also cataloged what he called "idols of the mind" -- systematic biases in human perception. We see patterns that aren't there. Words shape thought misleadingly. We inherit bad ideas. We see what we want to see. Recognizing these was the first step toward designing experiments that account for them.
He died in 1626 after catching pneumonia during an experiment stuffing a chicken with snow to test preservation. The experiment worked. He didn't survive to publish results. Within decades, his method became the foundation for the Royal Society.
Every A/B test, every controlled trial, every data-driven decision is downstream of Bacon's insight: knowledge is built through structured inquiry, not inherited wisdom. Design thinking, lean methodology, agile development -- all follow the same loop: observe, hypothesize, test, iterate. Bacon didn't invent curiosity. He invented the system for turning it into reliable knowledge.
