Baron Jean-Baptiste-Joseph Fourier (1768-1830) was also known as a Fourier transformer, Egyptologist, and Administrator. Fourier was a French mathematician, and also a physicist. His major influence was on The Analytical Theory of Heat in 1822.

## Time and Place of birth

Joseph Fourier was born on March 21, 1768, in Auxerre, France.

## Joseph Fourier Early life

Joseph Fourier was the son of a tailor, in his childhood, He attended the local military school and was taught by Benedictine monks at The Convent of St. Mark. As his capability in mathematics was outstanding, he became a teacher in the same school.

At the age of 9, he was an orphan. In the year 1780, he went to the Ecole Royale Militaire and mathematics became his real interest. Also, received first prize for his study on Bossut’s in the year 1783.

He decided to get trained for the priesthood in the year 1787 but continued doing mathematics.

## Fourier Joseph Adulthood

In the year 1793 Fourier joined politics in the local Revolutionary Committee. The results for the politics weren’t good and he tried to quit politics but that wasn’t possible and he was stuck in the revolution. In 1795 Fourier was chosen to go to Paris and study in the Ecole Normale.

And he joined the first batch and soon after the completion of the course, he joined as a teacher in Ecole Normale but soon switched to Ecole Polytechnique, and in between, he got arrested because of his political involvement but after 1795 he again got back into teaching Polytechnique.

At the Institute of Cairo, he was elected as the secretary till he was in Egypt, side by side kept working on mathematics. Fourier joined Napoleon’s army in 1798. And later, deserted his army and returned to Paris. From 1804 to 1807 he started his important mathematical works.

## Fourier Joseph Death

Jean-Baptiste Fourier Joseph died on 16 May 1830 he had a severe heart condition for quite a while and resulted in his death at the age of 62. He was buried in the Pere Lachaise Cemetery, in Paris. In Auxerre, a bronze statue was built.

## Joseph Fourier Education and Career

In his childhood, he went to a military school, and then became a mathematics teacher in the same school and for higher studies went to Ecole Normale Superieure.

Fourier Joseph was a mathematician with a great distinction. In the Scientific corps, he was denied the position but continued his studies and research in mathematics. Fourier is popular for the Fourier transforms as it includes heat transfer and vibrations.

In one of his papers he explained the study of the conduction of heat, his reasoning was on Newton’s law of cooling which was two-dimensional objects, this work of Fourier Joseph was in his well-known work “Fourier series”.

## Discovery

### The Greenhouse Effect

The first person to discover the greenhouse effect was Fourier; he studied Earth’s temperature from a mathematical point of view. He calculated the temperature day and night, and in summer and winter, and concluded that it would be much warmer.

He also calculated that it would be much colder than it is from the radiation of the sun.

When the energy from the sun peeks out and when the atmosphere is transparent to this radiation, which passes by and gives warmth to land and ocean, this energy, in turn, radiates as infra-red radiation. He also suggested that to sustain life on earth The Greenhouse Effect is necessary.
