On Sept 27, 1905, Albert Einstein’s famous equation, relating mass and energy, was first published in the physics journal Annalen der Physik in “Does the Inertia of a Body Depend Upon Its Energy Content?”
The Center for the History of Physics at the American Institute of Physics has an exhibit about the famous equation, here, and the PBS Nova program explained it in more tractable terms, here.
Another groundbreaking idea, Google, shares a birthday, though the year of its origin, 1998, was much later, of course.
