Jean-Louis Berlandier

Jean-Louis Berlandier (ca. 1805 – 1851) was a French-Mexican naturalist, physician, and anthropologist.
Berlandier was born in rural Fort l'Écluse, near France's border with Switzerland, and trained as a botanist in Geneva. During this time he probably served an apprenticeship to a pharmacist.
In his early 20s on the recommendation of his mentor, Auguste Pyrame De Candolle, he joined a Mexican scientific expedition as a biologist and plant specialist. Berlandier arrived at Pánuco, in the Mexican state of Veracruz, in December 1826. He collected plants in the surrounding area before continuing into Texas as part of the Mexican Boundary Commission. The commission left Mexico City on November 10, 1827, under the command of Manuel de Mier y Terán. Berlandier made botanical collections around Laredo, Texas, in February 1828 and around San Antonio, Gonzales, and San Felipe in March, April, and May 1828. After a brief trip to the interior of the country after he contacted malaria, he returned to San Antonio. He collected botanical specimens, made notes on animal species, and collected information on over forty Native American tribes in the surrounding territory, with special emphasis on the Comanche. In the fall of 1828, with a group of 30 Mexican soldiers led by Colonel José Francisco Ruiz, Berlandier accompanied Comanche leaders Reyuna and El Ronca on a bear and American Bison hunt on open lands northwest of San Antonio. From November 19 to December 18, Berlandier accompanied Ruiz to explore the silver mines on the San Saba River. On February 3, 1829, he also joined a force led by Antonio Elosúa to put down an uprising against the presidio commander at Goliad.
After the commission was dissolved in November 1829, Berlandier settled in Matamoros, Tamaulipas, and became a physician. He made additional botanical and animal collecting trips in Texas and other parts of Mexico, including returning to Goliad in 1834.
Berlandier compiled detailed information on the expeditions, including catalogues of plants, animals and Native American groups. This information is among the earliest ethnological studies of the tribes of the southern plains. One of his original manuscripts, dated 1834, is currently held by the Gilcrease Museum in Tulsa, Oklahoma.
Berlandier served as a captain, cartographer, and aide-de-camp in Mexico's Army of the North at the outbreak of hostilities between the United States and Mexico in the spring of 1846, under the command of General (later President) Mariano Arista. Captain Berlandier drew the first sketch maps of the battle of Palo Alto (May 8, 1846), which now reside in the Library of Congress. Berlandier's extensive knowledge of the region of south Texas and Tamaulipas, garnered from his field explorations to collect botanical specimens, was invaluable to General Arista.
After the Treaty of Guadalupe Hidalgo ended the fighting in February 1848, Berlandier was asked in 1850 to take part in the International Boundary Commission to define the border between Mexico and the United States. During the Mexican War he was placed in charge of the hospitals in Matamoros and served as an interpreter. In 1851 Berlandier drowned in the San Fernando River near Matamoros.
