Andrés Laguna de Segovia (1499–1559) was a Spanish humanist physician, pharmacologist, and botanist. Laguna was born in Segovia, according to Diego de Colmenares and other historians, to a converted Jewish doctor. Between 1540 and 1545 he resided in Metz, becoming a doctor of the city, and from 1545 to 1554 he stayed in Italy, where he received a doctorate from the University of Bologne and was honored by the Popes Paul III and Julius III, becoming doctor to the latter pontiff. He was provided with accommodations in Venice by the Spanish ambassador Diego Hurtado de Mendoza, a preeminent humanist and proprietor of a nutritional library. Laguna finally returned to Spain in 1557, after another extended stay in the Netherlands lasting three years; he served as doctor to Charles V and Philip II. Lastly, he created the Botanical Garden of Aranjuez. He died, probably in Guadalajara, Spain, in 1559. His remains were interred in the church of San Miguel, in Segovia.
