  • John Martin Schaeberle was a German-American astronomer. He was born Johann Martin Schäberle in Germany but immigrated as an infant to the United States. Most sources refer to him as John M.

He maintained his own private observatory and discovered three comets. In 1888 he became one of the inaugural astronomers at Lick Observatory. He designed the "Schaeberle camera" to take pictures of the Sun and its corona during total solar eclipses. He also discovered Procyon B, the faint companion star of Procyon, in 1896. He resigned from Lick Observatory when James E. Keeler was made its director instead of him in 1898, despite the fact that he had been acting director since the previous year. He never held another astronomical post. There are craters named after him on both the Moon and on Mars.
