In the 1920s, he was appointed as Commissioner of Agriculture and Labor. In that position, he traveled in Central and South America, aiding agricultural programs in Colombia, Venezuela, Bolivia and Dominican Republic. After serving as a university administrator and head of a major agency, he returned to his academic work in the fields of land use and agriculture in 1940 and later. He published several books on his studies in Puerto Rico and Latin America. ==Early life and education== Chardón (birth name: Carlos Eugenio Chardón Palacios) was born in Ponce, Puerto Rico, to Carlos Felix Chardón and Isabel Palacios Pelletier. His great-grandfather, Juan Bautista Chardón, a Catholic native of Champagne, France, immigrated to Puerto Rico from Louisiana in 1816, encouraged by the Royal Decree of Graces issued by the Spanish Crown, which was trying to attract new settlers to the island〔(Archivo General de Puerto Rico: Documentos ), Retrieved August 3, 2007〕 Chardón received his primary and secondary education in his hometown. In 1915 he began his studies in agriculture at the College of Agriculture and Mechanical Arts in Mayagüez.

He specialized in phytopathology and mycology, and studied diseases of sugar cane under the supervision of Professor Herbert H. Whetzel.〔(Mycologia )〕 Chardón earned his Master's degree in 1921 and became the first Puerto Rican mycologist. He returned to Puerto Rico and began a career in the fields of taxonomy of fungi, phytopathology, and agricultural development.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Carlos E.
