Cammille Flammarion, famous French astronomer. He was born in Montigny, France, on 21 February 1842 and disincarnated in June 1925. 

From 1862 he became a student of Spiritism. He met Allan Kardec and became close friends with him. 

We know that he was part of a group of spirits that included Allan Kardec, Léon Denis, Gabrielle Delanne and others. They came with the mission of awakening consciences and elaborating the Spiritist Doctrine to bring light and knowledge to minds eager to grow spiritually. They were the members of the Third Revelation team, bringing the renewed words of the Master Jesus. 

Camille Flammarion popularised astronomy in Europe, distinguishing himself as a pioneer in this science. He received the Motion Prize of the French Academy and his works were translated into almost every language. 

He was a precocious child, reading at the age of four and writing at the age of five. His interest in knowledge knew no bounds. He excelled in astronomy, philosophy and the study of the New Testament. At a very young age he still had to work hard to help support his father's household. He started as an apprentice metal engraver and received in return, house and food. He ate badly and slept little. He used his free time to study and read everything he could find. He read by candlelight and sometimes by moonlight alone. 

At the age of sixteen he published his first work, "The World before the Appearance of Man", which aroused great admiration among men of science. 

Shortly afterwards he joined the Paris Observatory, where he developed his great interest in astronomy but suffered the envy of the older scientists who would not tolerate a young man who knew more than they did. 

He published other works on astronomy and philosophy. He was a personal friend of Kardec. In the Spiritist Review, Kardec frequently mentioned Flammarion, as well as his experiences in developing his faculty as a psychographic medium. 

He was one of the first to practise hypnosis and taught classes on it. He was a passionate spiritist, especially in his later years; he claimed that spiritism phenomena were governed by scientific principles not yet discovered. On the death of his friend Kardec, before whose grave he made a heartfelt speech, he refused the presidency of the "Societé Spirite de Paris". 

Among his most famous works are: 

"Imaginary Worlds and Real Worlds" 
"Celestial wonders" 
"God in Nature" 
"Scientific Contemplations" 
"Atmosphere" 
"The haunted houses" 
“Urania” 
"Death and its mysteries" 
"The end of the world" 
"Plurality of inhabited worlds" 

Flammarion, in the words of Gabrielle Delanne, was a very wise philosopher who had the art of science and the science of art. 

A tireless writer and propagator of the Doctrine, he carried the banner of the Good News, accompanying Kardec in his work of dissemination and study. 

We owe to this great man important works on such subjects as reincarnation, the plurality of inhabited worlds, the evolution of the soul, communication with the spirits, and others. Above all, we owe him a new approach to science, pointing towards spirituality, to the existence of all creation. 

His name will always be next to those of the great men who gave their all for the spiritual growth of mankind.
