Costa Rican ornithologist Jose Zeledon was a man who saw ornithology as something to be dug into and explored until he gained as much knowledge about it as possible. Although his parents tried to give him the best possible education for the time period, he had to leave school and begin working as a pharmacy clerk at the age of 16. The pharmacy was owned by Dr. Alexander von Frantzius, a German naturalist and illustrator who moved to Costa Rica in 1854. In von Frantzius, Zeledon found a friend and mentor who would show him the proper way to collect specimens. In 1868, von Frantzius took Zeledon with him on his return to Germany; however, a stop-over in Washington, DC convinced Zeledon to remain in the city in order to work with the Smithsonian Institution. A thorough and enthusiastic naturalist, Zeledon was known as a kind and open-hearted man, well-liked by friends and colleagues. At the start of his career, the birds of Costa Rica were still mostly unknown, but his work greatly changed that. And although the last few years of his life were dedicated to running the pharmacy he’d inherited from von Frantzius, he never left behind his passion for Costa Rica’s birds, traveling to Washington, DC and serving as a friend and mentor to scientists visiting Costa Rica when he could spare the time.
