In 1938, the American astronomer George Ellery Hale died. He was inventor of the spectroheliograph (an instrument for observing the Sun in monochromatic light) and discovered the magnetic fields in sunspots. He was also the founder of the Monte Wilson observatory and designed the Monte Palomar observatory which however he never saw built. In the photo a crater on Mars dedicated to him.
