Zeno of Citium (sv: Zenon av Kition) founded a complete school of philosophy, called Stoicism because he taught at a porch (stoa) in downtown Athens.

Not the originator of Zeno's paradox, that's a different Zeno.

When Zeno first came to Athens, he asked a vendor where he might find a man like Socrates (469–399 BCE). A Cynic by the name of Crates was just passing by, and the vendor said "Follow that man". Zeno did, and learned much from Crates, in particular his disregard for common values.

Like most Greeks, Zeno admired Socrates, but he did not agree with the directions taken by Plato and Aristotle, and combined the character of Socrates with the philosophy of Heraclitus (535–475 BCE), instead. In ways, Stoicism is the philosophy most similar to that of Socrates himself. See for example the Academic Sceptics' stance that you could not know anything for certain, while Socrates and the Stoics would say that there is a class of things you can know for certain. (Looks like rationalists vs. empiricists again…).

Much of Greek philosophy ended up absorbing aspects of each other in the Roman period, so the distinctions mattered less.

… was a British statistician, who worked in the areas of quality control, time-series analysis, design of experiments, and Bayesian inference. Born in Gravesend, Kent. Got a PhD under supervision by Egon Pearson. Married Joan Fisher, whose father was R. A. Fisher.

He began to study chemistry, but was called up for service before finishing. During World War II, he performed experiments for the British Army exposing small animals to poison gas. To analyze the results of his experiments, he taught himself statistics from available texts.

"All models are wrong, but some are useful".

• Box-Jenkins models
• Box-Cox transformation
• Box-Behnken design
• etc.

An early figure in rhetoric, famous for the story where he learned to speak well by filling his mouth with stones and trying to speak past them.

The "first philosopher" (not really). Influenced other thinkers who went on to create the major schools of philosophy. For example, he taught Plato some things, who then taught Aristotle.

And Antisthenes took to himself Socrates' character more than his ideas, and taught the famous Diogenes the Cynic, who taught Crates, who taught Zeno of Citium, who created Stoic philosophy.
