1597: Astronomer Johannes Kepler replied to Galileo's letter of 4 August, 1597, urging him to be bold and proceed openly in his advocacy of Copernicanism.
1687: Astronomer, lens-maker, and academic Geminiano Montanari dies. He made the observation that Algol in the constellation of Perseus varies in brightness.
1715: Priest and philosopher Nicolas Malebranche dies. He was instrumental in introducing and disseminating the work of René Descartes and Gottfried Wilhelm Leibniz in France.
1729: Leonhard Euler mentions the gamma function in a letter to Christian Goldbach. Adrien-Marie Legendre gave the function its symbol and name in 1826.
1772: Using the San Pietro scrying engine, astronomer Charles Messier previews his discovery of a "galactic whirlpool" with a temporal accuracy of "within a year".
1773: The Whirlpool Galaxy is discovered by Charles Messier.
1890: Mathematician Georg Feigl born. He will work on the foundations of geometry and topology, studying fixed point theorems for n-dimensional manifolds. Feigl will be one of the initial authors of the Mathematisches Wörterbuch.
1976: The first electron micrograph of an Ebola viral particle is obtained by Dr. F. A. Murphy at the C.D.C.
1987: Physicist and academic Walter Houser Brattain dies. He shared the Nobel Prize in Physics in 1956 "for research on semiconductors and the discovery of the transistor effect."
