Astronomers Monument (2007)

The 12-meter obelisk with figures of six historically important astronomers, on the front lawn of Griffith Observatory. The dome in the background houses a 30-centimeter Zeiss refracting telescope.

The astronomers are, in chronological order: Hipparchus (2nd century BCE— calculated the motions of the sun and moon and compiled a star chart); Nicholas Copernicus (1473-1543— promoted the radical theory that the planets revolve around the sun); Galileo Galilei (1564-1642— various discoveries from the first astronomical use of a telescope challenged Catholic dogma); Johannes Kepler (1571-1630— described the true elliptical orbits of planets); Isaac Newton (1643-1727— described the laws of motion, gravitation, and optics, invented calculus and the reflecting telescope); and William Herschel (1738-1822— discovered the planet Uranus, infrared light, and the true nature of binary stars).
