2 October 1568 – 11 April 1626) was a Ragusan scientist. A
mathematician and physicist who studied in Italy,
England and Belgium,
his best results are mainly in physics, especially optics, and
mathematics. He was one of the few students of François Viète.

Born into the
Ghetaldi noble family, he was one of six children. He
was known for the application of algebra in geometry and his research
in the field of geometrical optics on which he wrote 7 works including
the Promotus Archimedus (1603) and the De resolutione et compositione
mathematica (1630). He also produced a leaflet with the solutions of
42 geometrical problems, Variorum problematum colletio, in 1607 and
set grounds of algebraization of geometry. His contributions to
geometry had been cited by Dutch physicist
Christiaan Huygens and
Edmond Halley, who calculated the orbit of what is known as Halley's
comet, in England.
Ghetaldi was the constructor of the parabolic mirror (66 cm in
diameter), kept today at the
National Maritime Museum
National Maritime Museum in London. He
was also a pioneer in making conic lenses. During his sejourn in
Padua he met Galileo Galilei, with whom he corresponded regularly. He
was a good friend to the French mathematician François Viète. He was
offered the post of professor of mathematics in
Leuven in Belgium, at
the time one of the most prestigious university centers in Europe.
He was also engaged in politics and was the envoy of the Republic of
Constantinople in 1606 as well as the member of the Great
and Small Council, the political bodies of the Republic. He was
married to Marija Sorkočević, who died giving birth to their third
daughter; they had three daughters: Anica, Franica and Marija.
Two notable localities in
Dubrovnik are associated with the name of
Getaldić: Bete's Cave, named after Marino's nickname, where he
conducted experiments with igniting mirrors; and Pozvizd, a key
strategic tower in the
Ston fortification system which he was
commissioned to build by the authorities of the Republic of Dubrovnik
