Giovanni Antonio Maria Zanardini (12 June 1804, Venice – 24 April 1878) was an Italian physician and botanist who specialized in the field of phycology.
In 1831 he obtained his medical doctorate from the University of Padua, followed by a degree in surgery and obstetrics from the University of Pavia three years later. During his career, he worked as a physician in Padua and Venice. For a period of time, he served as secretary of the Istituto Veneto Scienze e Lettere.[1]
The algae genus Zanardinia (in class Phaeophyceae)[2] is named after him, as are species with the epithet of zanardinii.[3]
