Astronomers Monument Figures

The six astronomers featured on the monument are among the most influential and important in history. The six figures represent the Greek astronomer Hipparchus (about 125 B.C.), Nicolaus Copernicus (1473-1543), Galileo Galilei (1564-1642), Johannes Kepler (1571-1630), Isaac Newton (1642-1727), and William Herschel (1738-1822). Albert Einstein was considered for inclusion, but planers ultimately decided it would be inappropriate to feature someone still alive (the monument was completed in 1934; Einstein died in 1955).
