This is named after Robert Hooke (1635-1703), the English scientist who formulated not only the law named after him, but remarkably, also proposed an undulating theory of light, introduced the term "cell" to biology, postulated elliptical orbits for the earth and moon, and proposed the inverse square law of gravitational attraction.
