|Image from a 2015 article (Ѻ) about a former Indiana public school teacher who was fired for admitting he was an atheist and refusing to pray during faculty meetings and other occasions, e.g. when the principle asked teachers to “pray so it wouldn’t snow, so that student testing wouldn’t be disrupted” and the teacher said, in reply to all recipients of the email, that he choose to “rely on the predictions of the meteorologists”; image brings to mind Johannes Wislicenus (1885).|
In 450BC, Empedocles taught atheism; the following is a retrospect citation to this:
“For it was fit that they who wrote should themselves have been eye-witnesses of those things concerning which they made assertions, or should accurately have ascertained them from those who had seen them; for they who write of things unascertained beat the air. For what did it profit Homer to have compose the Trojan war, and to have deceived many; or Hesiod, the register of the theogony of those whom he calls gods; or Orpheus, the three hundred and sixty-five gods, whom in the end of his life he rejects, maintaining in his precepts that there is one god? What profit did the sphaerography of the world's circle confer on Aratus, or those who held the same doctrine as he, except glory among men? And not even that did they reap as they deserved. And what truth did they utter? Or what good did their tragedies do to Euripides and Sophocles, or the other tragedians? Or their comedies to Menander and Aristophanes, and the other comedians? Or their histories to Herodotus and Thucydides? Or the shrines and the pillars of Hercules to Pythagoras, or the Cynic philosophy to Diogenes? What good did it do Epicurus to maintain that there is no providence; or Empedocles to teach atheism; or Socrates to swear by the dog, and the goose, and the plane-tree, and AEsculapius struck by lightning, and the demons whom he invoked? And why did he willingly die? What reward, or of what kind, did he expect to receive after death? What did Plato's system of culture profit him? Or what benefit did the rest of the philosophers derive from their doctrines, not to enumerate the whole of them, since they are numerous? But these things we say, for the purpose of exhibiting their useless and godless opinions.”— Theophilus (c.170AD) “Letter to Autolycus” 
In 1965, at the University of Jena, Germany, a chair of “scientific atheism” was established, its first occupant being German sociologist Olaf Klohr (Ѻ)(Ѻ), its inception, supposedly, having something to do with the “rather amused reaction of the western world” to Soviet astronaut Yuri Gagarin’s remarks that he found no trace of god “up there” or “out there”. 
In 2015, Libb Thims, together with co-host Thor, in their “Zerotheism for Kids” class, taught atheism, generally Thimsian atheism, to a group of six kids.
In 2016, the University of Miami began to establish its “Appignani Chair of Atheism, Humanism, and Secular Ethics”; as of 2018, the chair seems to be still unnamed.
The following are related quotes:
“You find me a state or society that threw off theocracy and threw off religion and said we adopt the teachings of Lucretius and Democritus and Galileo and Spinoza and Darwin and Russell and Jefferson and Thomas Paine, and we make those what we teach our children. We make that scientific and rational humanism our teaching. You find me that state, that did that, and fell into tyranny, and slavery, and famine, and torture, and then we’ll be on a level playing field.”— Christopher Hitchens (2008), “Debate with Peter Hitchens on Iraq War and Religion” (Ѻ), Grand Valley State University, Apr 3
