About Denis Jourdanet
- Denis Jourdanet (1 May 1815 – 6 May 1892) was a French physician and physiologist born in Juillan, Hautes-Pyrénées.
- He is remembered for pioneer studies of altitude sickness and hypoxia. As a wealthy physician, Jourdanet traveled extensively throughout mountainous regions of Mexico during the mid 19th century.
- Here he studied the effects of "mountain sickness" that climbers experienced at higher altitudes.
- From these studies he was the first person to make a connection between reduced atmospheric oxygen pressure and elevated erythrocyte (red blood cell) counts in humans.
- At the time Jourdanet referred to the condition as "barometric anoxemia".
- He was a friend and colleague to physiologist Paul Bert (1833–1886), to whom he provided the necessary equipment such as a decompression chamber for laboratory research of medical conditions caused by lowered oxygen pressure.
