Optician & physicist
Joseph von Fraunhofer
An orphaned glassmaker's apprentice who mapped the dark lines in the solar spectrum, which is how anybody knows what stars are made of.
Joseph Ritter von Fraunhofer was a German physicist and optical lens manufacturer. He made optical glass, an achromatic telescope, and objective lenses. He developed diffraction gratings and also invented the spectroscope. In 1814, he discovered and studied the dark absorption lines in the spectrum of the sun now known as Fraunhofer lines.
