He became meteorologist to the War (1842) and Navy (1848) departments and developed the use of the telegraph in assembling weather observation data by which he studied the progress of storms and laid the basis for scientific weather forecasting.

1798: Mathematician Karl Georg Christian von Staudt born. He will use synthetic geometry to provide a foundation for arithmetic.
1879: Glassblower, physicist, and inventor Johann Heinrich Wilhelm Geißler dies. He invented the Geissler tube, made of glass and used as a low pressure gas-discharge luminescence tube.
1961: Goldsboro B-52 crash: A bomber carrying two H-bombs breaks up in mid-air over North Carolina. The uranium core of one weapon remains lost.
1978: Soviet satellite Kosmos 954, with a nuclear reactor on board, burns up in Earth's atmosphere, scattering radioactive debris over Canada's Northwest Territories. Only 1% is recovered.
1988: Mathematician and academic Werner Fenchel dies. He established the basic results of convex analysis and nonlinear optimization theory which would, in time, serve as the foundation for nonlinear programming.
2016: Cognitive scientist and artificial intelligence researcher Marvin Minsky dies. Minsky's inventions include the first head-mounted graphical display (1963) and the confocal microscope (1957, a predecessor to today's widely used confocal laser scanning microscope).
