Johannes Kepler

Johannes Kepler was a German astronomer and mathematician, 1571 to 1630, whose three laws of planetary motion, drawn from Tycho Brahe's observations, later underpinned Newton's theory of gravitation.

Johannes Rydberg

Johannes Robert Rydberg (1854–1919) was a Swedish physicist at Lund University whose 1890 formula for spectral series, with the Rydberg constant, underlies Bohr's 1913 atomic model.

Johannes Stark

Johannes Stark (1874–1957) was a German experimental physicist who won the 1919 Nobel Prize in Physics for discovering the splitting of spectral lines in electric fields, the Stark effect.
