Amici was born in Modena, in present-day Italy. After studying at Bologna, he became professor of mathematics at Modena, and in 1831 was appointed inspector-general of studies in the Duchy of Modena. A few years later he was chosen director of the observatory at Florence, where he also lectured at the museum of natural history.[1] Amici died in Florence in 1863.
His name is best known for the improvements he effected in the mirrors of reflecting telescopes and especially in the construction of the microscope.[2] He was also a diligent and skillful observer, and busied himself not only with astronomical subjects, such as the double stars, the satellites of Jupiter and the measurement of the polar and equatorial diameters of the sun, but also with biological studies of the circulation of the sap in plants, the fructification of plants, infusoria etc.[1] He was the first to observe the pollen tube.[3]
He invented the dipleidoscope and also the direct vision prism.
