Ο Francis Aragon (François Arago, 1786-1853) was a French physicist, mathematician, astronomer and politician, who was distinguished for his scientific discoveries and his contribution to the progress of science in the 19th century. He was born on 26 February 1786 in Estaza, France. He studied at the Ecole Polytechnique in Paris, where he was distinguished for his outstanding abilities in mathematical physics.

Aragon became director of the Paris Observatory at a young age and was involved in important measurements related to geodesy, helping to determine the Paris meridian. His work in optics and electromagnetism was important, where he introduced the concept of polarization of light.

As a politician, he was an ardent defender of freedom and social justice. He was a member of the French National Assembly and in 1848 was Minister of Shipping and War, where he supported the abolition of slavery in the French colonies.

Freemasonry provided a space for the exchange of progressive ideas, in harmony with Aragon’s commitment to the principles of freedom, equality and social justice. Its Masonic relationships were consistent with the Enlightenment ideals it espoused, emphasizing rational thought, freedom, and the progress of society.

His personality combined scientific intelligence with social sensitivity, leaving a legacy in both science and human rights. He died on 2 October 1853, leaving behind a rich body of work that influenced generations of scientists.
