LOUIS DE BROGLIE 1892-1987

EARLY LIFE

• Louis de Broglie was a famous French scientist and mathematician.
• His full name was Louis-Victor-Pierre-Raymond, 7e duc de Broglie.
• He was born in Dieppe, France in 1892 into a wealthy and aristocratic family.
• He studied history in his early school life until 1910, where he thought science was better
• In 1913, he got a degree in physics.

WORLD WAR I LIFE

• When World War I came along, he got enlisted in the war and placed in the Eiffel Tower
• There, he worked on experiments with radio communications and engineering.
• After the war ended, him and his brother Maurice de Broglie got together and worked in their lab.

DISCOVERIES

• In the lab there were a lot of x-rays, which got Louis concerned more about light.
• So he decided to go after a doctoral degree in the field of physics to study the quantum theory.
• He thought that light was a type of wave-particle duality of matter
• He also thought that light had relations that showed the wavelength is inversely proportional to the momentum of a particle.
• Also the frequency of matter waves is directly proportional to the total energy of a particle that they appeared in a wave like motion.

SCIENCE NOW FAME LATER

• De Broglie’s theory did not become famous until it got the attention of other scientists who had similar questions as him.
• Scientists including G.P. Thomson and Clinton Davisson and Lester Germer decided to calculate his equations
• When they were proven correct in 1927, he gained much more fame.
• In 1929, He got awarded the 1929 Nobel Prize in physics.

DEATH

• Louis de Brogile got appointed as a professor of theoretical physics Henri Poincaré Institute in 1928.
• He stayed there until 1962 when he retired. He won the Kalinga Prize by UNESCO in 1952.
• He then became a foreign member of the British Royal Society, as well as the French Academy of Sciences.
• He died on March 19, 1987 in Louveciennes, France. He was 94 years old.
