Thomas Edison Patents the Phonograph (1878)

Though his formal schooling was limited to just three months of instruction before he was ten years old, Edison was one of the most prolific inventors of his time. His work in improving telegraph technology—particularly his discovery of a method for recording telegraph messages—led Edison to suspect he could do similar things with sound. Within months, the first working model of his phonograph was ready. Why, according to Edison, was he “taken aback” when his invention worked on the first try? Discuss

Lord Darnley, Second Husband of Mary Queen of Scots, Found Murdered (1567)

Though Darnley’s murder remains an unsolved mystery, one certainty is that at the time of his death, he was not well-liked.

He was found dead—but not from the blast. How was he killed, and who is suspected of his murder? Discuss
