Frederic Joliot-Curie (19 Mar 1900 - 14 Aug 1958)
He was a French physicist and physical chemist and husband of Marie Curie’s daughter Irène. He became personal assistant to Marie Curie at the Radium Institute, Paris. He collaborated with his wife and shared the Noble Prize for chemistry in 1935 “in recognition of their synthesis of new radioactive elements.” He also investigated the fission of uranium atoms and supervised the first atomic pile in France after WW II.
Baron Wilhelm von Biela (19 Mar 1782 - 18 Feb 1856)
He was an Austrian astronomer who measured the orbital period of a previously known comet as 6.6 years. This comet was also named after him. In 1846, it was observed that the comet broke into two and in 1852 the fragments returned as widely separated twin comets. After that, they were never seen again. But, in 1872 and 1885, when Earth crossed the path of the comet’s known orbit, bright meteor showers were observed. This provided the first evidence that some meteors are composed of fragments of disintegrated comets.
William Rutter Dawes (19 Mar 1799 - 15 Feb 1868)
He was an English amateur astronomer who built his private observatory and made measurements of binary stars. He discovered the inner Crepe Ring of Saturn on 25 Nov 1864. He was so keen on his sight with a telescope that he was called “Eagle-eyed Dawes”. He also devised a useful formula, the Dawes limit to calculate the resolving power of a telescope. He was the first to make an accurate map of Mars.

Emil Wiechert (26 Dec 1861 - 19 Mar 1928)
He was a German seismologist and physicist who invented the “inverted pendulum” seismograph in 1900. With the help of this, he was able to detect some of the inner structures of Earth. He made significant contributions to develop geophysics and seismology. He was the one who suggested that the Earth has an inner core made up of nickel-iron metal. He also made contributions in fundamental Physics including his electron theory and cathode rays.
Louis de Broglie (15 Aug 1892 - 19 Mar 1987)
He was a French physicist who won Noble Prize for physics for his research on dual nature of matter. He was best known for his research on quantum theory and he also discovered the wave nature of electrons. He argued that light behaves under some conditions as waves and other times as particles, so we should consider that it possess both wave and particle properties.

Britain's First Planetarium Opened
On this day in 1958, the London Planetarium which was Britain’s first planetarium opened. It is one of the largest planetariums. It is built at the site where a Cinema and a Restaurant existed but had been destroyed by a German bomb in 1940.
