Giovanni Maria Della Torre FRS (Rome, 16 June 1710 – Naples, 7 March 1782) was an Italian priest, naturalist and scientist who wrote several influential books on natural science and taught at several places around Italy.

[1] Under the guidance of the mathematician Domenico Chelucci (1681–1754), General of the Piarist Order, a wholly new type of teachers and professors was being trained here, who were taught the classics thoroughly, but also acquired a sound knowledge of the sciences, of geography and of history.

[1] Already in 1751 Della Torre had devised a method of forming over a lamp globules of glass which he then placed in cells of brass, adapted to a screw-barrel microscope.

Della Torre is particularly known for his observations of blood corpuscles described in a short publication entitled Praeclarissimo viro abati Noleto, which was printed in 1760.

Della Torre denied that they were spherical and described them as tiny membranaceous bags of a ring-like shape, filled with lymph, and pierced in the middle.
