Charles Marie de La Condamine
From Wikipedia, the free encyclopedia
Charles Marie de La Condamine (January 28, 1701 – February 4, 1774) was a French explorer, geographer, and mathematician.
La Condamine was born in Paris. He was trained for the military profession, but turned his attention to science and geographical exploration. Before his journey to South America, he took part in a scientific expedition in the Levant in 1731.

[edit] South America exploration
La Condamine became a member of the expedition that was sent to Peru in 1735 to determine the length of a degree of the meridian in the neighborhood of the equator; this work laid the basis for the determination of the length of the meter. The group was led by Louis Godin and included Pierre Bouguer, Antonio de Ulloa, and Jorge Juan y Santacilia. His associations with his principals were unhappy; the expedition was beset by many difficulties, and finally La Condamine split from the rest and made his way to Quito, Ecuador separately, discovering rubber in the process. Insufficient funds prevented La Condamine to return to France directly when he reached Quito. Thus he decided to take the trip down the Amazon, ultimately reaching Cayenne. His was the first scientific exploration of the Amazon. He returned to Paris in 1744 and published the results of his measurements and travels with a map of the Amazon in Mém. de l'Académie des Sciences, 1745 (English translation 1745-1747). This included the first descriptions by a European of the Casiquiare canal and the curare arrow poison prepared by the Amerindians. He also noted the correct use of quinine to fight malaria. The journal of his ten-year long voyage to South America was published in Paris in 1751. However, much of his observations of the Andean region were kept secret by the Spanish, as La Condamine had to submit its reports to the Spanish viceroy before he could leave Quito for his Amazon trip in 1744. These Noticias Secretas were eventually published in 1826.
[edit] Later years
On a visit to Rome La Condamine made careful measurements of the ancient buildings with a view to a precise determination of the length of the Roman foot. He also wrote in favour of inoculation, and on various other subjects, mainly connected with his work in South America. In 1760 he was nominated to the Academie Francaise. He died in Paris after a hernia operation.
