13th April 1941 death of Annie Jump Cannon
An American astronomer, Annie Jump Cannon worked with Edward Pickering at Harvard cataloging stellar spectra . Although being nearly deaf, she was responsible for dividing the stars into stellar classes, which today we know as OBAFGKM on the HR Diagram. In addition she discovered 300 variable stars and 5 novae.

Possibly the greatest mathematician of the 18th century Joseph Lagrange is best known for the Langrangian points, these are the 5 locations around a planet`s orbit where the gravitational forces and the orbital motion of the space craft, Sun and planets create a stable location from which to make observations.
