The 15 puzzle, invented in 1870s America, sparked a worldwide craze around 1880 — Sam Loyd famously offered a prize for an impossible configuration.

Is every starting layout solvable?

Yes. The game only ever shuffles into solvable configurations. The famously impossible arrangement Sam Loyd offered a prize for never appears.
