Explanation:

[STC0016777]. In 1943, while the mechanical engineer Richard James was experimenting with different spring types for use aboard ships, he came up with the idea for the Slinky by accident. When he saw the springs ‘walk’ over the floor, he couldn’t believe his eyes.

Betty was the one who came up with the name “Slinky.”
